+[appendix]
+== Migrating from Cowboy 2.4 to 2.5
+
+Cowboy 2.5 focused on making the test suites pass. A
+variety of new features, fixes and improvements have
+also been worked on.
+
+=== Features added
+
+* Add option `linger_timeout` to control how long
+  Cowboy will wait before closing the socket when
+  shutting down the connection. This helps avoid
+  the TCP reset problem HTTP/1.1 suffers from. The
+  default is now 1000 ms.
+
+* It is now possible to stream a response body
+  without using chunked transfer-encoding when the
+  protocol is HTTP/1.1. To enable this behavior,
+  simply pass the content-length header with the
+  expected size when initiating the streamed response.
+
+* Update Ranch to 1.6.2
+
+* Update Cowlib to 2.6.0
+
+=== Experimental features added
+
+* Websocket handlers now feature a commands-based interface.
+  The return value from the callbacks can now take the form
+  `{Commands, State}` where `Commands` can be frames to be
+  sent or commands yet to be introduced. New commands will
+  be available only through this new interface.
+
+* Add the `{active, boolean()}` Websocket handler command.
+  It allows disabling reading from the socket when `false`
+  is returned. `true` reenables reading from the socket.
+
+* Add the protocol option `logger` that allows configuring
+  which logger module will be used. The logger module must
+  follow the interface of the new `logger` module in Erlang/OTP 21,
+  or be set to `error_logger` to keep the old behavior. A
+  similar transport option exists in Ranch 1.6; both options
+  are necessary to override Cowboy's default behavior completely.
+
+* Add the `{log, Level, Format, Args}` stream handler command.
+  Making it a command rather than a direct call will simplify
+  silencing particular log messages.
+
+=== New functions
+
+* The function `cowboy_req:stream_events/3` streams one or more
+  text/event-stream events, encoding them automatically.
+
+* The functions `cowboy_req:read_and_match_urlencoded_body/2,3`
+  can be used to read, parse and match application/x-www-form-urlencoded
+  request bodies, in a similar way to `cowboy_req:match_qs/2`.
+
+=== Bugs fixed
+
+* Fix Erlang/OTP 21 warnings.
+
+* Ensure that the port number is always defined in the
+  Req object. When it is not provided in the request,
+  the default port number for the protocol being used
+  will be set.
+
+* Ensure stream handlers can run after `cowboy_stream_h`.
+
+* Honor the SETTINGS_ENABLE_PUSH HTTP/2 setting: don't
+  send PUSH frames to clients that disabled it.
+
+* Fix HTTP/2 `settings_timeout` option when the value
+  is set to `infinity`.
+
+* HTTP/1.1 responses will no longer include a trailer header
+  when the request had no te header.
+
+* HTTP/1.1 204 responses no longer send the transfer-encoding
+  header when `cowboy_req:stream_reply/2,3` is used to send
+  a response.
+
+* Improve HTTP/1.1 keepalive handling to avoid processing
+  requests that follow the final request that will receive
+  a response.
+
+* Improve the validation of HTTP/1.1 absolute-form requests.
+
+* When the `switch_protocol` is used after a response was
+  sent, Cowboy will no longer attempt to send the 101 informational
+  response for the protocol upgrade. This caused a crash of the
+  connection previously.
+
+* Errors that occur when a callback returned by
+  `content_types_provided` does not exist have been improved.
+
+* Prevent annoying error logs when using sendfile in
+  Erlang/OTP 20 and lower.
+
+* Add missing frame types to `websocket_handle`.
+
+* A test suite has been added for RFC8297 to ensure that
+  103 informational responses can be sent.
+
+* Numerous test cases have been fixed, improved or removed in order
+  to make the test suites pass. Most of the failures were caused
+  by broken tests.
+
+* Some misguiding or incorrect statements in the documentation
+  have been removed or clarified.

+
+<p>Cowboy 2.5 focused on making the test suites pass. A variety of new features, fixes and improvements have also been worked on.</p>
+<h2 id="_features_added">Features added</h2>
+<ul><li>Add option <code>linger_timeout</code> to control how long Cowboy will wait before closing the socket when shutting down the connection. This helps avoid the TCP reset problem HTTP/1.1 suffers from. The default is now 1000 ms.
+</li>
+<li>It is now possible to stream a response body without using chunked transfer-encoding when the protocol is HTTP/1.1. To enable this behavior, simply pass the content-length header with the expected size when initiating the streamed response.
+</li>
+<li>Update Ranch to 1.6.2
+</li>
+<li>Update Cowlib to 2.6.0
+</li>
+</ul>
+<h2 id="_experimental_features_added">Experimental features added</h2>
+<ul><li>Websocket handlers now feature a commands-based interface. The return value from the callbacks can now take the form <code>{Commands, State}</code> where <code>Commands</code> can be frames to be sent or commands yet to be introduced. New commands will be available only through this new interface.
+</li>
+<li>Add the <code>{active, boolean()}</code> Websocket handler command. It allows disabling reading from the socket when <code>false</code> is returned. <code>true</code> reenables reading from the socket.
+</li>
+<li>Add the protocol option <code>logger</code> that allows configuring which logger module will be used. The logger module must follow the interface of the new <code>logger</code> module in Erlang/OTP 21, or be set to <code>error_logger</code> to keep the old behavior. A similar transport option exists in Ranch 1.6; both options are necessary to override Cowboy&apos;s default behavior completely.
+</li>
+<li>Add the <code>{log, Level, Format, Args}</code> stream handler command. Making it a command rather than a direct call will simplify silencing particular log messages.
+</li>
+</ul>
+<h2 id="_new_functions">New functions</h2>
+<ul><li>The function <code>cowboy_req:stream_events/3</code> streams one or more text/event-stream events, encoding them automatically.
+</li>
+<li>The functions <code>cowboy_req:read_and_match_urlencoded_body/2,3</code> can be used to read, parse and match application/x-www-form-urlencoded request bodies, in a similar way to <code>cowboy_req:match_qs/2</code>.
+</li>
+</ul>
+<h2 id="_bugs_fixed">Bugs fixed</h2>
+<ul><li>Fix Erlang/OTP 21 warnings.
+</li>
+<li>Ensure that the port number is always defined in the Req object. When it is not provided in the request, the default port number for the protocol being used will be set.
+</li>
+<li>Ensure stream handlers can run after <code>cowboy_stream_h</code>.
+</li>
+<li>Honor the SETTINGS_ENABLE_PUSH HTTP/2 setting: don&apos;t send PUSH frames to clients that disabled it.
+</li>
+<li>Fix HTTP/2 <code>settings_timeout</code> option when the value is set to <code>infinity</code>.
+</li>
+<li>HTTP/1.1 responses will no longer include a trailer header when the request had no te header.
+</li>
+<li>HTTP/1.1 204 responses no longer send the transfer-encoding header when <code>cowboy_req:stream_reply/2,3</code> is used to send a response.
+</li>
+<li>Improve HTTP/1.1 keepalive handling to avoid processing requests that follow the final request that will receive a response.
+</li>
+<li>Improve the validation of HTTP/1.1 absolute-form requests.
+</li>
+<li>When the <code>switch_protocol</code> is used after a response was sent, Cowboy will no longer attempt to send the 101 informational response for the protocol upgrade. This caused a crash of the connection previously.
+</li>
+<li>Errors that occur when a callback returned by <code>content_types_provided</code> does not exist have been improved.
+</li>
+<li>Prevent annoying error logs when using sendfile in Erlang/OTP 20 and lower.
+</li>
+<li>Add missing frame types to <code>websocket_handle</code>.
+</li>
+<li>A test suite has been added for RFC8297 to ensure that 103 informational responses can be sent.
+</li>
+<li>Numerous test cases have been fixed, improved or removed in order to make the test suites pass. Most of the failures were caused by broken tests.
+</li>
+<li>Some misguiding or incorrect statements in the documentation have been removed or clarified.
+</li>
+</ul>

+[appendix]
+== Migrating from Cowboy 2.5 to 2.6
+
+Cowboy 2.6 greatly refactored the HTTP/2 code, a large
+part of which was moved to Cowlib and is now used by
+both the Cowboy server and the Gun client.
+
+A large number of tickets were also closed which
+resulted in many bugs fixed and many features and
+options added, although some of them are still
+experimental.
+
+=== Features added
+
+* Add support for the PROXY protocol header.
+  It can be enabled via the `proxy_header` option.
+  The proxy information can then be found under
+  the `proxy_info` key in the Req object.
+
+* Allow using sendfile tuples in `cowboy_req:stream_body/3`
+  and in the data command in stream handlers. The only
+  caveat is that when using `cowboy_compress_h` the
+  sendfile tuples may have to be converted to in-memory
+  data in order to compress them. This is the case for
+  gzip compression.
+
+* The stream handlers `cowboy_stream_h` and
+  `cowboy_compress_h` are now documented.
+
+* Add the `chunked` option to allow disabling chunked
+  transfer-encoding for HTTP/1.1 connections.
+
+* Add the `http10_keepalive` option to allow disabling
+  keep-alive for HTTP/1.0 connections.
+
+* Add the `idle_timeout` option for HTTP/2.
+
+* Add the `sendfile` option to both HTTP/1.1 and HTTP/2.
+  It allows disabling the sendfile syscall entirely for
+  all connections. It is recommended to disable sendfile
+  when using VirtualBox shared folders.
+
+* Add the `rate_limited/2` callback to REST handlers.
+
+* Add the `deflate_opts` option to Websocket handlers that
+  allows configuring deflate options for the
+  permessage-deflate extension.
+
+* Add the `charset` option to `cowboy_static`.
+
+* Add support for the SameSite cookie attribute.
+
+* Update Ranch to 1.7.0
+
+* Update Cowlib to 2.7.0
+
+=== Experimental features added
+
+* Add support for range requests (RFC7233) in REST handlers.
+  This adds two new callbacks: `ranges_accepted/2` and
+  `range_satisfiable/2` along with the user-specified
+  `ProvideRangeCallback/2`.
+
+* Add automatic handling of range requests to REST handlers
+  that return the callback `auto` from `ranges_accepted/2`.
+  Cowboy will call the configured `ProvideCallback` and
+  then split the ouput automatically for the ranged response.
+
+* Enable range requests support in `cowboy_static`.
+
+* Add the `{deflate, boolean()}` Websocket handler
+  command to disable permessage-deflate compression
+  temporarily.
+
+* Add the `compress_threshold` option which allows
+  configuring how much data must be present in a
+  response body to compress it. This only applies
+  to non-streamed bodies at this time.
+
+* Add the `compress_buffering` option which allows
+  controlling whether some buffering may be done
+  when streaming a response body. Change the default
+  behavior to not buffer to make sure it works by
+  default in all scenarios.
+
+* Add the `{set_options, map()}` command to stream
+  handlers and Websocket handlers. This can be used
+  to update options on a per-request basis. Allow
+  overriding the `idle_timeout` option for both
+  HTTP/1.1 and Websocket, the `cowboy_compress_h`
+  options for HTTP/1.1 and HTTP/2 and the `chunked`
+  option for HTTP/1.1.
+
+=== Bugs fixed
+
+* Do not send a content-length automatically with
+  304 responses. This status code allows a content-length
+  that corresponds to what would have been sent for a 200
+  response, but is never followed by a body.
+
+* HTTP/2 streams are now terminated once the body
+  has been sent fully, instead of immediately once
+  the stop command is returned (by default when the
+  request process exits). Metrics will therefore
+  more accurately represent when a stream ended.
+
+* Terminate connection processes gracefully when the
+  parent process exists or when sys:terminate/2,3
+  is called.
+
+* Automatically ignore the boundary parameter of multipart
+  media types when using REST handlers. This is a special
+  parameter that may change with all requests and cannot
+  be predicted.
+
+* Fix parsing of the accept header when it contains charset
+  parameters. They are case insensitive and will now be
+  lowercased, like for accept-charset and content-type.
+
+* Handle the charset parameter using `charsets_provided`
+  when it is present in the accept header when using
+  REST handlers.
+
+* Don't select charsets when the q-value is 0 in REST
+  handlers.
+
+* Handle accept-charset headers that include a wildcard
+  in REST handlers.
+
+* Only send a charset header when the content-type
+  negotiated is of type text in REST handlers.
+
+* Remove the default charset iso-8859-1 from REST
+  handlers when no other is provided. This has been
+  removed from the HTTP specifications for a long time.
+
+* Many cases where a content-type header was sent
+  unnecessarily in the REST handlers response have
+  been fixed.
+
+* Handle error_response commands in `cowboy_metrics_h`.
+
+* A number of types and function specifications were
+  fixed or improved. Dialyzer is now run against both
+  the code and tests to help uncover issues.
+
+* An undefined `cowboy_router` behavior has been
+  documented.

+[appendix]
+== Migrating from Cowboy 2.6 to 2.7
+
+Cowboy 2.7 improves the HTTP/2 code with optimizations
+around the sending of DATA and WINDOW_UPDATE frames;
+graceful shutdown of the connection when the client is
+going away; and rate limiting mechanisms. New options
+and mechanisms have also been added to control the
+amount of memory Cowboy ends up using with both HTTP/1.1
+and HTTP/2. Much, but not all, of this work was done
+to address HTTP/2 CVEs about potential denial of service.
+
+In addition, many of the experimental features introduced
+in previous releases have been marked stable and are now
+documented.
+
+Cowboy 2.7 requires Erlang/OTP 20.0 or greater.
+
+=== Features added
+
+* Cowboy is now compatible with both Ranch 1.7 and the
+  upcoming Ranch 2.0.
+
+* The number of HTTP/2 WINDOW_UPDATE frames Cowboy sends
+  has been greatly reduced. Cowboy now applies heuristics
+  to determine whether it is necessary to update the window,
+  based on the current window size and the amount of data
+  requested by streams (the `cowboy_req:read_body/2` length
+  for example). Six new options have been added to control
+  this behavior: `connection_window_margin_size`,
+  `connection_window_update_threshold`,
+  `max_connection_window_size`, `max_stream_window_size`,
+  `stream_window_margin_size` and
+  `stream_window_update_threshold`.
+
+* HTTP/2 connections will now be shut down gracefully
+  when receiving a GOAWAY frame. Cowboy will simply
+  wait for existing streams to finish before closing
+  the connection.
+
+* Functions that stream the response body now have
+  backpressure applied. They now wait for a message
+  to be sent back. The message will be held off when
+  using HTTP/2 and the buffer sizes exceed either
+  `max_connection_buffer_size` or `max_stream_buffer_size`.
+  For HTTP/1.1 the data is sent synchronously and we
+  rely instead on the TCP backpressure.
+
+* A new HTTP/2 option `stream_window_data_threshold`
+  can be used to control how little the DATA frames that
+  Cowboy sends can get. By default Cowboy will wait for
+  the window to be large enough to send either everything
+  queued or to reach the default maximum frame size of
+  16384 bytes.
+
+* A new HTTP/2 option `max_receive_frame_rate` can be
+  used to control how fast the server is willing to receive
+  frames. By default it will accept 1000 frames every 10
+  seconds.
+
+* A new HTTP/2 option `max_reset_stream_rate` can be
+  used to control the rate of errors the server is
+  willing to accept. By default it will accept 10
+  stream resets every 10 seconds.
+
+* Flow control for incoming data has been implemented
+  for HTTP/1.1. Cowboy will now wait for the user code
+  to ask for the request body before reading it from
+  the socket. The option `initial_stream_flow_size`
+  controls how much data Cowboy will read without
+  being asked.
+
+* The HTTP/1.1 and HTTP/2 option `logger` is now
+  documented.
+
+* The Websocket option `validate_utf8` has been
+  added. It can be used to disable the expensive UTF-8
+  validation for incoming text and close frames.
+
+* The experimental commands based Websocket interface
+  is now considered stable and has been documented.
+  The old interface is now deprecated.
+
+* A new Websocket handler command `shutdown_reason`
+  can be used to change the normal exit reason of
+  Websocket processes. By default `normal` is used;
+  with this command the exit reason can be changed
+  to `{shutdown, ShutdownReason}`.
+
+* The experimental stream handlers `cowboy_metrics_h`
+  and `cowboy_tracer_h` are now considered stable and
+  have been documented.
+
+* The stream handler commands `set_options` and `log`
+  are now considered stable and have been documented.
+
+* The router is now capable of retrieving dispatch
+  rules directly from the `persistent_term` storage
+  (available starting from Erlang/OTP 21.2).
+
+* Support for the status codes 208 and 508 has been
+  added.
+
+* Update Ranch to 1.7.1.
+
+* Update Cowlib to 2.8.0.
+
+=== Experimental features added
+
+* It is now possible to read the response body from any
+  process, as well as doing any other `cowboy_req`
+  operations. Since this is not recommended due to
+  race condition concerns this feature will always
+  remain experimental.
+
+=== New functions
+
+* The function `cowboy_req:filter_cookies/2` has been
+  added. It can be called before parsing/matching
+  cookies in order to filter out undesirables. The
+  main reason for doing this is to avoid most parse
+  errors that may occur when dealing with Web browsers
+  (which have a string-based Javascript interface to
+  cookies that is very permissive of invalid content)
+  and to be able to recover in other cases.
+
+* The function `cowboy_req:cast/2` has been added.
+  It can be used to send events to stream handlers.
+
+=== Bugs fixed
+
+* A number of fixes and additions were made to address the
+  HTTP/2 CVEs CVE-2019-9511 through CVE-2019-9518, except
+  for CVE-2019-9513 which required no intervention as the
+  relevant protocol feature is not implemented by Cowboy.
+
+* The HTTP/2 connection window could become larger than the
+  protocol allows, leading to errors. This has been corrected.
+
+* The presence of empty header names in HTTP/2 requests now
+  results in the request to be rejected.
+
+* Cowboy will now remove headers specific to HTTP/1.1
+  (the hop by hop headers such as connection or upgrade)
+  when building an HTTP/2 response.
+
+* A bug in the HTTP/2 code that resulted in the failure to
+  fully send iolist response bodies has been fixed. Cowboy
+  would just wait indefinitely in those cases.
+
+* It was possible for a final empty HTTP/2 DATA frame to get
+  stuck and never sent when the window reached 0 and the remote
+  end did not increase the window anymore. This has been
+  corrected.
+
+* Cowboy now uses the host header when the HTTP/2
+  :authority pseudo header is missing. A common scenario
+  where this occurs is when proxies translate incoming
+  HTTP/1.1 requests to HTTP/2.
+
+* HTTP/1.1 connections are now properly closed when the
+  user code sends less data than advertised in the response
+  headers.
+
+* Cowboy will now close HTTP/1.1 connections immediately when
+  a header line is missing a colon separator. Previously it
+  was waiting for more data.
+
+* It was possible for Cowboy to receive stray timeout messages
+  for HTTP/1.1 connections, resulting in crashes. The timeout
+  handling in HTTP/1.1 has been reworked and the issue should
+  no longer occur.
+
+* The type for the Req object has been updated to accept
+  custom fields as was already documented.
+
+* The authentication scheme returned when parsing the
+  authorization header is now case insensitive, which
+  means it will be returned as lowercase.
+
+* Cowboy no longer discards data that follows a Websocket
+  upgrade request. Note that the protocol does not allow
+  sending data before receiving a successful Websocket
+  upgrade response, so this fix is more out of principle
+  rather than to fix a real world issue.
+
+* The `cowboy_static` handler will now properly detect
+  the type of files that have an uppercase or mixed
+  extension component.
+
+* The `cowboy_static` handler is now consistent across all
+  supported platforms. It now explicitly rejects `path_info`
+  components that include a forward slash, backward slash
+  or NUL character.
+
+* The update to Ranch 1.7.1 fixes an issue with the PROXY
+  protocol that would cause checksum verification to fail.
+
+* The HTTP/1.1 error reason for `stream_error` mistakenly
+  contained an extra element. It has now been removed.
+
+* The `PartialReq` given to the `early_error` stream handler
+  callback now includes headers when the protocol is HTTP/2.
+
+* A bug where the stacktrace was incorrect in error messages
+  has been fixed. The problem occurred when an exception
+  occurred in the handler's terminate callback.
+
+* The REST flowchart for POST, PATCH and PUT has received
+  a number of fixes and had to be greatly reworked as a
+  result. When the method is PUT, we do not check for
+  the location header in the response. When the resource
+  doesn't exist and the method was PUT the flowchart was
+  largely incorrect. A 415 response may occur after the
+  `content_types_accepted` callback and was missing from
+  the flowchart.
+
+* The documentation for `content_types_accepted` now
+  includes the media type wildcard that was previously
+  missing.
+
+* The documentation for a type found in `cow_cookie`
+  was missing. A manual page for `cow_cookie` was added
+  and can be found in the Cowlib documentation.

+[appendix]
+== Migrating from Cowboy 2.7 to 2.8
+
+Cowboy 2.8 contains many optimizations for all
+protocols. HTTP/1.1 has received the largest
+improvements and Cowboy will now be able to
+handle noticeably more requests. Thanks to
+the folks at Stressgrid for helping identify that
+the performance was lower than it should have been
+and for benchmarking my many changes and experiments.
+
+Cowboy 2.8 also contains a small number of tweaks
+and bug fixes. Cowboy 2.8 is the first Cowboy release,
+ever, to be consistently green on all tested platforms.
+This is mostly due to the reworking of some test cases,
+but a few bugs were discovered and fixed in the process.
+
+Cowboy 2.8 requires Erlang/OTP 22.0 or greater. It may
+also work out of the box with Erlang/OTP 21.3 but this
+was not tested and is not supported.
+
+=== Features added
+
+* Cowboy will now use `active,N` instead of `active,once`
+  to receive data from the socket. This greatly improves
+  the performance and allows Cowboy to process more
+  requests, especially for HTTP/1.1. The `active_n`
+  protocol option can be configured to change the
+  `active,N` value. The default is 100 for all protocols.
+
+* Add a `linger_timeout` option for HTTP/2. The default
+  is 1000, or one second. This helps ensure that the
+  final GOAWAY frame will be properly received by clients.
+
+* The function `cowboy_req:parse_header/2,3` will now
+  parse the headers `access-control-request-headers`,
+  `access-control-request-method`, `content-encoding`,
+  `content-language`, `max-forwards`, `origin`,
+  `proxy-authorization` and `trailer`.
+
+* A Performance chapter has been added to the guide.
+  More content will be added in future releases.
+
+* Update Cowlib to 2.9.1.
+
+=== Experimental features added
+
+* A `protocols` protocol option allows configuring which
+  protocol will be used for clear listeners. Setting it
+  to `[http2]` will disable HTTP/1.1 entirely. This feature
+  will be extended in a future release.
+
+=== Features modified
+
+* The default value for HTTP/1.1's `max_keepalive` option
+  has been increased. It now allows 1000 requests before
+  gracefully closing the connection.
+
+* The default value for HTTP/2's `max_received_frame_rate`
+  option has been increased. It now allows 10000 frames every
+  10 seconds.
+
+* Cowboy will now accept whitespace in cookie names. This
+  is in line with the recommended parsing algorithm for the
+  upcoming cookie RFC update, and corresponds to what browsers
+  are doing.
+
+=== Bugs fixed
+
+* The number of Transport:send/2 calls has been optimized
+  for HTTP/2. Reducing the number of calls has a noticeable
+  impact on the number of requests that can be processed.
+
+* Trying to use `cowboy_req:reply/4` with a status code of
+  204 or 304 and a non-empty response body will now result
+  in a crash. Using `cowboy_req:stream_reply/2,3` with 204
+  or 304 and then attempting to send a body will also result
+  in a crash. These status codes disallow response bodies
+  and trying to send one will break HTTP/1.1 framing.
+
+* A crash has been fixed related to HTTP/1.1 pipelining.
+  The bug was most likely introduced in Cowboy 2.6 when
+  flow control was added for HTTP/1.1 request bodies.
+
+* The HTTP/1.1 protocol code could get stuck because of flow
+  control. This has been corrected.
+
+* A crash has been fixed for HTTP/1.1. It occurred when
+  a flow control update was requested (such as reading
+  the request body) after the body was fully read.
+
+* The timeout was incorrectly reset sometimes when a stream
+  (a pair of request/response) terminated. This has been
+  corrected.
+
+* Handling of hibernation for Websocket has been improved.
+  Websocket over HTTP/2 now supports hibernating. Stray
+  messages no longer cancel hibernation.
+
+* The `cowboy_compress_h` stream handler will now ignore
+  malformed accept-encoding headers instead of crashing.
+
+* The manual pages for `cowboy:start_clear(3)` and
+  `cowboy:start_tls(3)` now mentions that some protocol
+  options may be documented in the releevant stream
+  handler.
+
+* The manual page for `cowboy_req:parse_header(3)` was
+  corrected. When an unsupported header is given the
+  function crashes, it does not return an `undefined` tuple.
+
+* The routing algorithm description in the user guide has
+  been improved.
+
+* The test suites are now consistently green on all tested
+  platforms. Most of the test failures were caused by flaky
+  tests. Avoiding the use of timeouts fixed most of them.
+  A small number of tests had to be reworked.

+[appendix]
+== Migrating from Cowboy 2.8 to 2.9
+
+Cowboy 2.9 implements graceful shutdown of connection
+processes for both HTTP/1.1 and HTTP/2 connections.
+
+Cowboy 2.9 is the first release to support the much
+awaited Erlang/OTP 24 out of the box. While users that
+were using Ranch 2.0 already were ready for OTP 24,
+the Ranch version used by Cowboy out of the box was
+not compatible and had to be updated.
+
+Cowboy 2.9 also contains a small number of tweaks
+and bug fixes.
+
+Cowboy 2.9 requires Erlang/OTP 22.0 or greater.
+
+=== Features added
+
+* Cowboy will now gracefully shutdown HTTP/1.1 and HTTP/2
+  connections when the supervisor asks the connection
+  process to exit, or when `sys:terminate/2,3` is used.
+  Two new configuration options were added for HTTP/2
+  to determine the timeouts for the graceful shutdown
+  steps.
+
+* REST handler `AcceptCallback` can now return `{created, URI}`
+  or `{see_other, URI}` to determine what response status code
+  should be sent (typically to differentiate between a new
+  resource and an update). The return value `{true, URI}` is
+  now deprecated.
+
+* Update Ranch to 1.8.0.
+
+* Update Cowlib to 2.11.0.
+
+=== Bugs fixed
+
+* Fix concurrent body streaming getting stuck with HTTP/2.
+  The alarm could get into blocking state indefinitely
+  when two or more request processes were streaming bodies.
+
+* Fix HTTP/2 rate limiting using the wrong default values
+  in some cases.
+
+* Don't produce an error report when the request process
+  exited normally (`normal` or `shutdown` exit reasons).
+
+* Fix `cowboy_tracer_h` to support trace messages without
+  timestamps.

+
+<p>Cowboy 2.9 implements graceful shutdown of connection processes for both HTTP/1.1 and HTTP/2 connections.</p>
+<p>Cowboy 2.9 is the first release to support the much awaited Erlang/OTP 24 out of the box. While users that were using Ranch 2.0 already were ready for OTP 24, the Ranch version used by Cowboy out of the box was not compatible and had to be updated.</p>
+<p>Cowboy 2.9 also contains a small number of tweaks and bug fixes.</p>
+<p>Cowboy 2.9 requires Erlang/OTP 22.0 or greater.</p>
+<h2 id="_features_added">Features added</h2>
+<ul><li>Cowboy will now gracefully shutdown HTTP/1.1 and HTTP/2 connections when the supervisor asks the connection process to exit, or when <code>sys:terminate/2,3</code> is used. Two new configuration options were added for HTTP/2 to determine the timeouts for the graceful shutdown steps.
+</li>
+<li>REST handler <code>AcceptCallback</code> can now return <code>{created, URI}</code> or <code>{see_other, URI}</code> to determine what response status code should be sent (typically to differentiate between a new resource and an update). The return value <code>{true, URI}</code> is now deprecated.
+</li>
+<li>Update Ranch to 1.8.0.
+</li>
+<li>Update Cowlib to 2.11.0.
+</li>
+</ul>
+<h2 id="_bugs_fixed">Bugs fixed</h2>
+<ul><li>Fix concurrent body streaming getting stuck with HTTP/2. The alarm could get into blocking state indefinitely when two or more request processes were streaming bodies.
+</li>
+<li>Fix HTTP/2 rate limiting using the wrong default values in some cases.
+</li>
+<li>Don&apos;t produce an error report when the request process exited normally (<code>normal</code> or <code>shutdown</code> exit reasons).
+</li>
+<li>Fix <code>cowboy_tracer_h</code> to support trace messages without timestamps.
+</li>
+</ul>

+[appendix]
+== Migrating from Cowboy 2.9 to 2.10
+
+Cowboy 2.10 is a maintenance release adding support
+for Erlang/OTP 26. The main change is a Cowlib update
+to fix a compilation error that only occurs starting
+from OTP 26.
+
+Cowboy 2.10 requires Erlang/OTP 22.0 or greater.
+
+=== Features added
+
+* Add support for `Default` value of SameSite
+  cookie attribute.
+
+* Add support for the `stale-*` cache-control directives
+  from RFC 5861.
+
+* Update Cowlib to 2.12.1.
+
+=== Bugs fixed
+
+* Fix a compilation error in Cowlib when using Erlang/OTP 26.
+
+* Fix data sent after RST_STREAM in HTTP/2 in rare cases.
+
+* Fix parsing of RST_STREAM frames to properly handle
+  frames that have a valid length but were not fully
+  received yet.
+
+* Remove the obsolete `Version` cookie attribute.
+
+* Handle more edge cases for cookie parsing based on updates
+  to the RFC 6265bis draft.
+
+* Make Basic auth parsing ignore unknown authentication
+  parameters and generally update the code to conform
+  to RFC 7617.
+
+* Fix URI template reserved expansion of %-encoded.
+
+* Update structured headers implementation to RFC 8941.

+== Performance
+
+This chapter describes the performance characteristics
+of Cowboy and offers suggestions to get the most
+performance out of your application.
+
+=== One process per connection
+
+The first version of Cowboy featured a single process
+per connection, whereas the current version of Cowboy
+features one process per connection plus one process
+per request. This has a negative impact on performance,
+but is necessary in order to provide a common interface
+for both HTTP/1.1 and HTTP/2 (as well as future HTTP
+versions).
+
+It is still possible to use a single process per
+connection, and avoid the creation of additional
+processes for each request, by implementing a
+stream handler to process the requests. This can
+be done for all requests, or just for a single
+endpoint depending on the application's needs.
+
+Stream handlers provide an asynchronous interface
+and must not block, so the implementation will
+be very different from normal Cowboy handlers,
+but the performance gains are important enough
+to justify it in some cases.

+<p>cowboy_compress_h - Compress stream handler</p>
+<h2 id="_description">Description</h2>
+<p>The module <code>cowboy_compress_h</code> compresses response bodies automatically when the client supports it. It will not try to compress responses that already have a content encoding.</p>
+<p>Normal responses will only be compressed when their size is lower than the configured threshold. Streamed responses are always compressed, including when the sendfile command is used. Because the file must be read in memory to be compressed, this module is <strong>not</strong> suitable for automatically compressing large files.</p>

+<p>Configuration for the HTTP/2 protocol.</p>
+<p>This configuration is passed to Cowboy when starting listeners using <code>cowboy:start_clear/3</code> or <code>cowboy:start_tls/3</code> functions.</p>
+<p>It can be updated without restarting listeners using the Ranch functions <code>ranch:get_protocol_options/1</code> and <code>ranch:set_protocol_options/2</code>.</p>
+<p>The default value is given next to the option name:</p>
+<dl><dt>active_n (100)</dt>
+<dd><p>The number of packets Cowboy will request from the socket at once. This can be used to tweak the performance of the server. Higher values reduce the number of times Cowboy need to request more packets from the port driver at the expense of potentially higher memory being used.</p>
+</dd>
+<dt>connection_type (supervisor)</dt>
+<dd><p>Whether the connection process also acts as a supervisor.</p>
+</dd>
+<dt>connection_window_margin_size (65535)</dt>
+<dd><p>Extra amount in bytes to be added to the window size when updating the connection window. This is used to ensure that there is always some space available in the window.</p>
+</dd>
+<dt>connection_window_update_threshold (163840)</dt>
+<dd><p>The connection window will only get updated when its size becomes lower than this threshold, in bytes. This is to avoid sending too many <code>WINDOW_UPDATE</code> frames.</p>
+</dd>
+<dt>enable_connect_protocol (false)</dt>
+<dd><p>Whether to enable the extended CONNECT method to allow protocols like Websocket to be used over an HTTP/2 stream. This option is experimental and disabled by default.</p>
+</dd>
+<dt>goaway_initial_timeout (1000)</dt>
+<dd><p>Time in ms to wait for any in-flight stream creations before stopping to accept new streams on an existing connection during a graceful shutdown.</p>
+</dd>
+<dt>goaway_complete_timeout (3000)</dt>
+<dd><p>Time in ms to wait for ongoing streams to complete before closing the connection during a graceful shutdown.</p>
+</dd>
+<dt>idle_timeout (60000)</dt>
+<dd><p>Time in ms with no data received before Cowboy closes the connection.</p>
+</dd>
+<dt>inactivity_timeout (300000)</dt>
+<dd><p>Time in ms with nothing received at all before Cowboy closes the connection.</p>
+</dd>
+<dt>initial_connection_window_size (65535)</dt>
+<dd><p>Initial window size in bytes for the connection. This is the total amount of data (from request bodies for example) that may be buffered by the connection across all streams before the user code explicitly requests it.</p>
+<p>Note that this value cannot be lower than the default.</p>
+</dd>
+<dt>initial_stream_window_size (65535)</dt>
+<dd><p>Initial window size in bytes for new streams. This is the total amount of data (from request bodies for example) that may be buffered by a single stream before the user code explicitly requests it.</p>
+</dd>
+<dt>linger_timeout (1000)</dt>
+<dd><p>Time in ms that Cowboy will wait when closing the connection. This is necessary to avoid the TCP reset problem as described in the <a href="https://tools.ietf.org/html/rfc7230#section-6.6">section 6.6 of RFC7230</a>. In HTTP/2&apos;s case the GOAWAY message might also be lost when closing the connection immediately.</p>
+</dd>
+<dt>logger (error_logger)</dt>
+<dd><p>The module that will be used to write log messages.</p>
+</dd>
+<dt>max_concurrent_streams (infinity)</dt>
+<dd><p>Maximum number of concurrent streams allowed on the connection.</p>
+</dd>
+<dt>max_connection_buffer_size (16000000)</dt>
+<dd><p>Maximum size of all stream buffers for this connection, in bytes. This is a soft limit used to apply backpressure to handlers that send data faster than the HTTP/2 connection allows.</p>
+</dd>
+<dt>max_connection_window_size (16#7fffffff)</dt>
+<dd><p>Maximum connection window size in bytes. This is used as an upper bound when calculating the window size, either when reading the request body or receiving said body.</p>
+</dd>
+<dt>max_decode_table_size (4096)</dt>
+<dd><p>Maximum header table size in bytes used by the decoder. This is the value advertised to the client. The client can then choose a header table size equal or lower to the advertised value.</p>
+</dd>
+<dt>max_encode_table_size (4096)</dt>
+<dd><p>Maximum header table size in bytes used by the encoder. The server will compare this value to what the client advertises and choose the smallest one as the encoder&apos;s header table size.</p>
+</dd>
+<dt>max_frame_size_received (16384)</dt>
+<dd><p>Maximum size in bytes of the frames received by the server. This value is advertised to the remote endpoint which can then decide to use any value lower or equal for its frame sizes.</p>
+</dd>
+<dt>max_frame_size_sent (infinity)</dt>
+<dd><p>Maximum size in bytes of the frames sent by the server. This option allows setting an upper limit to the frame sizes instead of blindly following the client&apos;s advertised maximum.</p>
+<p>Note that actual frame sizes may be lower than the limit when there is not enough space left in the flow control window.</p>
+</dd>
+<dt>max_received_frame_rate ({10000, 10000})</dt>
+<dd><p>Maximum frame rate allowed per connection. The rate is expressed as a tuple <code>{NumFrames, TimeMs}</code> indicating how many frames are allowed over the given time period. This is similar to a supervisor restart intensity/period.</p>
+</dd>
+<dt>max_reset_stream_rate ({10, 10000})</dt>
+<dd><p>Maximum reset stream rate per connection. This can be used to protect against misbehaving or malicious peers that do not follow the protocol, leading to the server resetting streams, by limiting the number of streams that can be reset over a certain time period. The rate is expressed as a tuple <code>{NumResets, TimeMs}</code>. This is similar to a supervisor restart intensity/period.</p>
+</dd>
+<dt>max_stream_buffer_size (8000000)</dt>
+<dd><p>Maximum stream buffer size in bytes. This is a soft limit used to apply backpressure to handlers that send data faster than the HTTP/2 connection allows.</p>
+</dd>
+<dt>max_stream_window_size (16#7fffffff)</dt>
+<dd><p>Maximum stream window size in bytes. This is used as an upper bound when calculating the window size, either when reading the request body or receiving said body.</p>
+</dd>
+<dt>preface_timeout (5000)</dt>
+<dd><p>Time in ms Cowboy is willing to wait for the connection preface.</p>
+</dd>
+<dt>proxy_header (false)</dt>
+<dd><p>Whether incoming connections have a PROXY protocol header. The proxy information will be passed forward via the <code>proxy_header</code> key of the Req object.</p>
+</dd>
+<dt>sendfile (true)</dt>
+<dd><p>Whether the sendfile syscall may be used. It can be useful to disable it on systems where the syscall has a buggy implementation, for example under VirtualBox when using shared folders.</p>
+</dd>
+<dt>settings_timeout (5000)</dt>
+<dd><p>Time in ms Cowboy is willing to wait for a SETTINGS ack.</p>
+</dd>
+<dt>stream_handlers ([cowboy_stream_h])</dt>
+<dd><p>Ordered list of stream handlers that will handle all stream events.</p>
+</dd>
+<dt>stream_window_data_threshold (16384)</dt>
+<dd><p>Window threshold in bytes below which Cowboy will not attempt to send data, with one exception. When Cowboy has data to send and the window is high enough, Cowboy will always send the data, regardless of this option.</p>
+</dd>
+<dt>stream_window_margin_size (65535)</dt>
+<dd><p>Extra amount in bytes to be added to the window size when updating a stream&apos;s window. This is used to ensure that there is always some space available in the window.</p>
+</dd>
+<dt>stream_window_update_threshold (163840)</dt>

+<p>Filter cookie headers.</p>
+<p>This function is meant to be used before attempting to parse or match cookies in order to remove cookies that are not relevant and are potentially malformed. Because Cowboy by default crashes on malformed cookies, this function allows processing requests that would otherwise result in a 400 error.</p>
+<p>Malformed cookies are unfortunately fairly common due to the string-based interface provided by browsers and this function provides a middle ground between Cowboy&apos;s strict behavior and chaotic real world use cases.</p>
+<p>Note that there may still be crashes even after filtering cookies because this function does not correct malformed values. Cookies that have malformed values should probably be unset in an error response or in a redirect.</p>
+<p>This function can be called even if there are no cookies in the request.</p>

+<p>When the cookie header is missing or empty, <code>[]</code> is returned.</p>
+<p>This function will crash on invalid cookie data. Because invalid cookies are fairly common when dealing with browsers (because of the string interface that the Javascript API provides), it is recommended to filter the cookie header value before attempting to parse it. This can be accomplished by calling the function <a href="../cowboy_req.filter_cookies">cowboy_req:filter_cookies(3)</a> first. This does not guarantee that parsing succeeds. If it still fails it is recommended to send an error response or redirect with instructions to delete the relevant cookies:</p>

+<p>Read, parse and match a urlencoded request body against constraints.</p>
+<p>This function reads the request body and parses it as <code>application/x-www-form-urlencoded</code>. It then applies the given field constraints to the urlencoded data and returns the result as a map.</p>
+<p>The urlencoded media type is used by Web browsers when submitting HTML forms using the POST method.</p>
+<p>Cowboy will only return the values specified in the fields list, and ignore all others. Fields can be either the key requested; the key along with a list of constraints; or the key, a list of constraints and a default value in case the key is missing.</p>
+<p>This function will crash if the key is missing and no default value is provided. This function will also crash if a constraint fails.</p>
+<p>The key must be provided as an atom. The key of the returned map will be that atom. The value may be converted through the use of constraints, making this function able to extract, validate and convert values all in one step.</p>
+<p>Cowboy needs to read the full body before parsing. By default it will read bodies of size up to 64KB. It is possible to provide options to read larger bodies if required.</p>
+<p>Cowboy will automatically handle protocol details including the expect header, chunked transfer-encoding and others.</p>
+<p>Once the body has been read, Cowboy sets the content-length header if it was not previously provided.</p>
+<p>This function can only be called once. Calling it again will result in undefined behavior.</p>

+<p>An <code>ok</code> tuple is returned.</p>
+<p>Desired values are returned as a map. The key is the atom that was given in the list of fields, and the value is the optionally converted value after applying constraints.</p>
+<p>The map contains the same keys that were given in the fields.</p>
+<p>An exception is triggered when the match fails.</p>
+<p>The Req object returned in the tuple must be used from that point onward. It contains a more up to date representation of the request. For example it may have an added content-length header once the body has been read.</p>

+<p>Stream events.</p>
+<p>This function should only be used for <code>text/event-stream</code> responses when using server-sent events. Cowboy will automatically encode the given events to their text representation.</p>
+<p>This function may be called as many times as needed after initiating a response using the <a href="../cowboy_req.stream_reply">cowboy_req:stream_reply(3)</a> function.</p>
+<p>The second argument indicates if this call is the final call. Use the <code>nofin</code> value until you know no more data will be sent. The final call should use <code>fin</code> (possibly with an empty data value) or be a call to the <a href="../cowboy_req.stream_trailers">cowboy_req:stream_trailers(3)</a> function.</p>
+<p>Note that not using <code>fin</code> for the final call is not an error; Cowboy will take care of it when the request handler terminates if needed. Depending on the resource it may however be more efficient to do it as early as possible.</p>
+<p>You do not need to handle HEAD requests specifically as Cowboy will ensure no data is sent when you call this function.</p>

-<p>Configuration for the HTTP/2 protocol.</p>
-<p>This configuration is passed to Cowboy when starting listeners using <code>cowboy:start_clear/3</code> or <code>cowboy:start_tls/3</code> functions.</p>
-<p>It can be updated without restarting listeners using the Ranch functions <code>ranch:get_protocol_options/1</code> and <code>ranch:set_protocol_options/2</code>.</p>
-<p>The default value is given next to the option name:</p>
-<dl><dt>connection_type (supervisor)</dt>
-<dd><p>Whether the connection process also acts as a supervisor.</p>
-</dd>
-<dt>enable_connect_protocol (false)</dt>
-<dd><p>Whether to enable the extended CONNECT method to allow protocols like Websocket to be used over an HTTP/2 stream. This option is experimental and disabled by default.</p>
-</dd>
-<dt>env (#{})</dt>
-<dd><p>Middleware environment.</p>
-</dd>
-<dt>inactivity_timeout (300000)</dt>
-<dd><p>Time in ms with nothing received at all before Cowboy closes the connection.</p>
-</dd>
-<dt>initial_connection_window_size (65535)</dt>
-<dd><p>Initial window size for the connection. This is the total amount of data (from request bodies for example) that may be buffered by the connection across all streams before the user code explicitly requests it.</p>
-<p>Note that this value cannot be lower than the default.</p>
-</dd>
-<dt>initial_stream_window_size (65535)</dt>
-<dd><p>Initial window size for new streams. This is the total amount of data (from request bodies for example) that may be buffered by a single stream before the user code explicitly requests it.</p>
-</dd>
-<dt>max_concurrent_streams (infinity)</dt>
-<dd><p>Maximum number of concurrent streams allowed on the connection.</p>
-</dd>
-<dt>max_decode_table_size (4096)</dt>
-<dd><p>Maximum header table size used by the decoder. This is the value advertised to the client. The client can then choose a header table size equal or lower to the advertised value.</p>
-</dd>
-<dt>max_encode_table_size (4096)</dt>
-<dd><p>Maximum header table size used by the encoder. The server will compare this value to what the client advertises and choose the smallest one as the encoder&apos;s header table size.</p>
-</dd>
-<dt>max_frame_size_received (16384)</dt>
-<dd><p>Maximum size of the frames received by the server. This value is advertised to the remote endpoint which can then decide to use any value lower or equal for its frame sizes.</p>
-</dd>
-<dt>max_frame_size_sent (infinity)</dt>
-<dd><p>Maximum size of the frames sent by the server. This option allows setting an upper limit to the frame sizes instead of blindly following the client&apos;s advertised maximum.</p>
-<p>Note that actual frame sizes may be lower than the limit when     there is not enough space left in the flow control window.</p>
-</dd>

       <description>Cowboy is a small, fast and modern HTTP server for Erlang/OTP.
 Cowboy aims to provide a complete modern Web stack. This includes HTTP/1.1, HTTP/2, Websocket, Server-Sent Events and Webmachine-based REST.
 Cowboy comes with functions for introspection and tracing, enabling developers to know precisely what is happening at any time. Its modular design also easily enable developers to add instrumentation.

       <description>Erlang is more than a language, it is also an operating system for your applications. Erlang developers rarely write standalone modules, they write libraries or applications, and then bundle those into what is called a release. A release contains the Erlang VM plus all applications required to run the node, so it can be pushed to production directly.
 This chapter walks you through all the steps of setting up Cowboy, writing your first application and generating your first release.</description>

 It is built on top of Ranch. Please see the Ranch guide for more information about how the network connections are handled.

       <description>A listener is a set of processes that listens on a port for new connections. Incoming connections get handled by Cowboy. Depending on the connection handshake, one or another protocol may be used.

       <description>Cowboy does nothing by default.
 To make Cowboy useful, you need to map URIs to Erlang modules that will handle the requests. This is called routing.
-When Cowboy receives a request, it tries to match the requested host and path to the configured routes. When there&amp;apos;s a match, the route&amp;apos;s associated handler is executed.
-Routes need to be compiled before they can be used by Cowboy. The result of the compilation is the dispatch rules.</description>
+Cowboy routes requests using the following algorithm:
+If no configured host matches the request URI, a 400 response is returned.  Otherwise, the first configured host that matches the request URI will be used. Only the paths configured for this host will be considered.  If none of the configured paths found in the previous step match the request URI, a 404 response is returned.</description>

       <description>Loop handlers are a special kind of HTTP handlers used when the response can not be sent right away. The handler enters instead a receive loop waiting for the right message before it can send a response.
 Loop handlers are used for requests where a response might not be immediately available, but where you would like to keep the connection open for a while in case the response arrives. The most known example of such practice is known as long polling.</description>

+This function is meant to be used before attempting to parse or match cookies in order to remove cookies that are not relevant and are potentially malformed. Because Cowboy by default crashes on malformed cookies, this function allows processing requests that would otherwise result in a 400 error.
+Malformed cookies are unfortunately fairly common due to the string-based interface provided by browsers and this function provides a middle ground between Cowboy&amp;apos;s strict behavior and chaotic real world use cases.</description>

       <description>Erlang is the ideal platform for writing Web applications. Its features are a perfect match for the requirements of modern Web applications.
 The Web is concurrent When you access a website there is little concurrency involved. A few connections are opened and requests are sent through these connections. Then the web page is displayed on your screen. Your browser will only open up to 4 or 8 connections to the server, depending on your settings.</description>

       <description>Cowboy is a small, fast and modern HTTP server for Erlang/OTP.
 Cowboy aims to provide a complete modern Web stack. This includes HTTP/1.1, HTTP/2, Websocket, Server-Sent Events and Webmachine-based REST.
 Cowboy comes with functions for introspection and tracing, enabling developers to know precisely what is happening at any time. Its modular design also easily enable developers to add instrumentation.

Erlang developers rarely write standalone modules, they write libraries or applications, and then bundle those into what is called a release. A release contains the Erlang VM plus all applications required to run the node, so it can be pushed to production directly.

 It is built on top of Ranch. Please see the Ranch guide for more information about how the network connections are handled.

       <description>Cowboy does nothing by default.
 To make Cowboy useful, you need to map URIs to Erlang modules that will handle the requests. This is called routing.
-When Cowboy receives a request, it tries to match the requested host and path to the configured routes. When there&amp;apos;s a match, the route&amp;apos;s associated handler is executed.
-Routes need to be compiled before they can be used by Cowboy. The result of the compilation is the dispatch rules.</description>
+Cowboy routes requests using the following algorithm:
+If no configured host matches the request URI, a 400 response is returned.  Otherwise, the first configured host that matches the request URI will be used. Only the paths configured for this host will be considered.  If none of the configured paths found in the previous step match the request URI, a 404 response is returned.</description>

       <description>A stream is the set of messages that form an HTTP request/response pair.
 The term stream comes from HTTP/2. In Cowboy, it is also used when talking about HTTP/1.1 or HTTP/1.0. It should not be confused with streaming the request or response body.
 All versions of HTTP allow clients to initiate streams. HTTP/2 is the only one also allowing servers, through its server push feature. Both client and server-initiated streams go through the same process in Cowboy.</description>

 Middlewares give you complete control over how requests are to be processed. You can add your own middlewares to the mix or completely change the chain of middlewares as needed.
 Cowboy will execute all middlewares in the given order, unless one of them decides to stop processing.</description>
