---------------------------------------------------------------------
--- HIGHLIGHTS ------------------------------------------------------
---------------------------------------------------------------------
OTP-15523 Application(s): ftp
Related Id(s): OTP-15352, PR-1968
Add support for FTPES (explicit FTP over TLS).
OTP-16611 Application(s): kernel
Related Id(s): OTP-16749
A compatibility adaptor for gen_tcp to use the new
socket API has been implemented (gen_tcp_socket). Used
when setting the kernel application variable
inet_backend = socket.
OTP-16686 Application(s): debugger, erts, kernel, stdlib
Extended error information for failing BIF calls as
proposed in EEP 54 has been implemented.
When a BIF call from the Erlang shell fails, more
information about which argument or arguments that were
in error will be printed. The same extended error
information will by proc_lib, common_test, and qlc when
BIF calls fail.
For applications that wish to provide the same extended
error information, there are new functions
erl_error:format_exception/3 and
erl_error:format_exception/4.
There is a new error/3 BIF that allows applications or
libraries to provide extended error information in the
same way for their own exceptions.
OTP-16706 Application(s): compiler
Related Id(s): ERL-1281
Variables bound between the keywords 'try' and 'of' can
now be used in the clauses following the 'of' keyword
(that is, in the success case when no exception was
raised).
OTP-16718 Application(s): erts, kernel, stdlib
Related Id(s): PR-2735
Process aliases as outlined by EEP 53 has been
introduced. Process aliases is introduced in order to
provide a lightweight mechanism that can prevent late
replies after timeout or connection loss. For more
information, see EEP 53 and the documentation of the
new alias/1 BIF and the new options to the monitor/3
BIF.
The call operation in the framework used by gen_server,
gen_statem, and gen_event has been updated to utilize
alias in order to prevent late responses. The
gen_statem behavior still use a proxy process in the
distributed case, since it has always prevented late
replies and aliases wont work against pre OTP 24 nodes.
The proxy process can be removed in OTP 26.
The alias feature also made it possible to introduce
new functions similar to the erpc:receive_response()
function in the gen behaviors, so the new functions
gen_server:receive_response(),
gen_statem:receive_response(),
gen_event:receive_response() have also been introduced.
OTP-16800 Application(s): wx
The application has been completely rewritten in order
to use wxWidgets version 3 as its base.
Add basic documentation generated from the wxWidgets
project.
OTP-16824 Application(s): compiler
Related Id(s): PR-2664, PR-3006
*** POTENTIAL INCOMPATIBILITY ***
Compiler warnings and errors now include column numbers
in addition to line numbers.
When a compiler message is emitted, the source line is
printed along with a marker (a ^ character) that
indicates the column position of the issue. The option
'brief' removes the printout of the source line.
The compiler option {error_location, line | column} has
been added. The default value is column. Besides adding
column numbers to compilation warnings and errors, the
option also determines whether column numbers are
included in abstract code. If tools stop working,
setting the environment variable ERL_COMPILER_OPTIONS
can help (include {error_location, line}).
The compiler will now call the function
PT:parse_transform_info/0 in parse transforms (if it
exists). It can be used by parse transforms to signal
that they can only handle line numbers in abstract
code.
OTP-16885 Application(s): erts
Related Id(s): PR-2745
The BeamAsm JIT-compiler has been added to Erlang/OTP.
The JIT-compiler is enabled by default on most x86
64-bit platforms that have a C++ compiler that can
compile C++17. To verify that a JIT enabled emulator is
running you can use erlang:system_info(emu_flavor).
For more information see the internal documentation of
BeamAsm in erts.
OTP-16949 Application(s): edoc
Related Id(s): OTP-17192, PR-2803
*** POTENTIAL INCOMPATIBILITY ***
EDoc, the Erlang documentation engine, hits version 1.0
with this release, which means a few changes.
EDoc is now capable of emitting EEP-48 doc chunks. This
means that, with some configuration, community projects
can now provide documentation for shell_docs the same
way that OTP libraries did since OTP 23.0.
The @spec and @type EDoc tags have been deprecated.
These are not supported with the new chunk-generating
doclet and layout. Moreover, previously when there was
a redundant @spec tag and -spec attribute defined for
the same function, the @spec tag would take precedence.
Now, the -spec attribute takes precedence and is more
important. The same is true for redundant @type tags
and -type attributes. Warnings are now emitted when
such redundant entries are found.
See the Doc chunks chapter in the Edoc User's Guide for
more details.
OTP-16964 Application(s): compiler
Generators in list and binary comprehensions will now
raise a {bad_generator,Generator} exception if the
generator has an incorrect type (instead of raising an
ad-hoc badarg or badarih exception). Similarly, when a
filter does not evaluate to a boolean, a
{bad_filter,Filter} exception will be raised. Some
minor bugs in the compilation of binary comprehensions
have also been fixed.
OTP-16981 Application(s): compiler
Related Id(s): ERL-1113
Some compiler warnings, such as the warning for an
expression whose result is ignored, could not be
suppressed by assigning to a variable beginning with
'_', but only by assigning to the anonymous variable
('_'). This has now been changed so that any warning
that can be suppressed by assigning to the anonymous
variable can also be suppressed by assigning to a
variable beginning with '_'.
OTP-17044 Application(s): ssl
Related Id(s): PR-2654
Make TLS handshakes in Erlang distribution concurrent.
OTP-17213 Application(s): wx
Related Id(s): PR-3027
Added support for wxWebView.
OTP-17226 Application(s): compiler
Related Id(s): GH-4019, PR-4545
The compiler will now inline funs that are used only
once immediately after their definition.
---------------------------------------------------------------------
--- POTENTIAL INCOMPATIBILITIES -------------------------------------
---------------------------------------------------------------------
OTP-15107 Application(s): stdlib
Related Id(s): ERL-1381, PR-2813
Time-outs in gen_statem with relative time 0 did not
behave quite according to the intended model. This has
now been corrected.
The correction introduces a small potential
incompatibility e.g when combining a state time-out
with inserted events, and the inserted event does a
state change in the state with the time-out. Before
this correction the state time-out could be delivered
even after the second state change, but now it is
guaranteed that a state time-out is only delivered in
the state it was started for, even in this corner case.
OTP-16560 Application(s): megaco
All the pre-v3 codec(s) (prev3a, prev3b and prev3c) was
deprecated in OTP-23.0. They have now been removed.
OTP-16656 Application(s): crypto
The functions and cipher names that were deprecated in
OTP-23.0 are now removed.
OTP-16749 Application(s): erts, kernel
Related Id(s): OTP-14601
The experimental new socket API has been further
developed. Some backwards incompatible changes with
respect to OTP 23 have been made.
The control message format has been changed so a
decoded value is now in the 'value' field instead of in
the 'data' field. The 'data' field now always contains
binary data.
Some type names have been changed regarding message
headers and control message headers.
socket:bind/2 now returns plain ok instead of {ok,
Port} which was only relevant for the inet and inet6
address families and often not interesting. To find out
which port was chosen use socket:sockname/1.
OTP-16809 Application(s): kernel
Related Id(s): ERL-1313
Change the value of the tag head returned by
disk_log:info/1 from {ok, Head} to just Head.
OTP-16811 Application(s): kernel
Remove the support for distributed disk logs. The new
function disk_log:all/0 is to be used instead of
disk_log:accessible_logs/0. The function
disk_log:close/1 is to be used instead of
disk_log:lclose/1,2.
OTP-16824 Application(s): compiler

OTP-16878 Application(s): erts
The code loader has been rewritten in order to be able
to load JIT:ed code. As a consequence of this, it is no
longer possible to load HiPE code.
OTP-16943 Application(s): os_mon
Related Id(s): OTP-16906
The temporarily introduced configuration parameter
memsup_improved_system_memory_data has been removed.
OTP-16945 Application(s): erts
Change escripts to output any errors or warnings to
standard error instead of standard out.

OTP-17216 Application(s): kernel
Related Id(s): PR-2989
The behaviour for gen_tcp:connect/3,4 has been changed
to not per default bind to an address, which allows the
network stack to delay the address and port selection
to when the remote address is known. This allows better
port re-use, and thus enables far more outgoing
connections, since the ephemeral port range no longer
has to be a hard limit.
There is a theoretical possibility that this behaviour
change can affect the set of possible error values, or
have other small implications on some platforms.

Compiler warnings and errors now include column numbers
in addition to line numbers.
When a compiler message is emitted, the source line is
printed along with a marker (a ^ character) that
indicates the column position of the issue. The option
'brief' removes the printout of the source line.
The compiler option {error_location, line | column} has
been added. The default value is column. Besides adding
column numbers to compilation warnings and errors, the
option also determines whether column numbers are
included in abstract code. If tools stop working,
setting the environment variable ERL_COMPILER_OPTIONS
can help (include {error_location, line}).
The compiler will now call the function
PT:parse_transform_info/0 in parse transforms (if it
exists). It can be used by parse transforms to signal
that they can only handle line numbers in abstract
code.

The BeamAsm JIT-compiler has been added to Erlang/OTP.
The JIT-compiler is enabled by default on most x86
64-bit platforms that have a C++ compiler that can
compile C++17. To verify that a JIT enabled emulator is
running you can use erlang:system_info(emu_flavor).
For more information see the internal documentation of
BeamAsm in erts.

By default all ERTS internal memory allocators based on
alloc_util will now use their own separate carrier pool
for migration of carriers instead of using a node
global carrier pool. This was the default behavior
between OTP 17 and OTP 21, but changed to use a node
global carrier pool as of OTP 22.0. Usage of the node
global carrier pool proved troublesome since it had a
tendency to spread long lived blocks into allocators
with normally short lived blocks causing increased
memory fragmentation. The node global carrier pool
behavior as well as other behaviors can be configured
using the +M<S>cp command line argument.

New functions have been added to the maps module:
merge_with/3, intersect/2, intersect_with/3,
filtermap/2, from_keys/2, and maps:foreach/2.
maps:merge_with/3 is the same as merge/2 but takes an
extra fun that is used to combine items with the same
key.
maps:intersect/2 computes the intersection of two maps.
maps:intersect_with/3 is the same as intersect/2 but
takes an extra fun that is used to combine intersecting
items.
maps:filtermap/2 allows filtering and mapping of a map
in a single pass.
maps:from_keys/2 constructs a map from a list of keys
and a single value and can be used to to optimize sets
operations such as from_list/1, filter/2,
intersection/2, and subtract/2.
maps:foreach/2 allows iteration over a map without
returning any value.

Process aliases as outlined by EEP 53 has been

provide a lightweight mechanism that can prevent late
replies after timeout or connection loss. For more
information, see EEP 53 and the documentation of the
new alias/1 BIF and the new options to the monitor/3
BIF.
The call operation in the framework used by gen_server,
gen_statem, and gen_event has been updated to utilize
alias in order to prevent late responses. The
gen_statem behavior still use a proxy process in the
distributed case, since it has always prevented late
replies and aliases wont work against pre OTP 24 nodes.
The proxy process can be removed in OTP 26.
The alias feature also made it possible to introduce
new functions similar to the erpc:receive_response()
function in the gen behaviors, so the new functions
gen_server:receive_response(),
gen_statem:receive_response(),
gen_event:receive_response() have also been introduced.

*** HIGHLIGHT ***
Extended error information for failing BIF calls as
proposed in EEP 54 has been implemented.
When a BIF call from the Erlang shell fails, more
information about which argument or arguments that were
in error will be printed. The same extended error
information will by proc_lib, common_test, and qlc when
BIF calls fail.
For applications that wish to provide the same extended
error information, there are new functions
erl_error:format_exception/3 and
erl_error:format_exception/4.
There is a new error/3 BIF that allows applications or
libraries to provide extended error information in the
same way for their own exceptions.

*** HIGHLIGHT ***
Process aliases as outlined by EEP 53 has been
introduced. Process aliases is introduced in order to
provide a lightweight mechanism that can prevent late
replies after timeout or connection loss. For more
information, see EEP 53 and the documentation of the
new alias/1 BIF and the new options to the monitor/3
BIF.
The call operation in the framework used by gen_server,
gen_statem, and gen_event has been updated to utilize
alias in order to prevent late responses. The
gen_statem behavior still use a proxy process in the
distributed case, since it has always prevented late
replies and aliases wont work against pre OTP 24 nodes.
The proxy process can be removed in OTP 26.
The alias feature also made it possible to introduce
new functions similar to the erpc:receive_response()
function in the gen behaviors, so the new functions
gen_server:receive_response(),
gen_statem:receive_response(),
gen_event:receive_response() have also been introduced.

New functions have been added to the maps module:
merge_with/3, intersect/2, intersect_with/3,
filtermap/2, from_keys/2, and maps:foreach/2.
maps:merge_with/3 is the same as merge/2 but takes an
extra fun that is used to combine items with the same
key.
maps:intersect/2 computes the intersection of two maps.
maps:intersect_with/3 is the same as intersect/2 but
takes an extra fun that is used to combine intersecting
items.
maps:filtermap/2 allows filtering and mapping of a map
in a single pass.
maps:from_keys/2 constructs a map from a list of keys
and a single value and can be used to to optimize sets
operations such as from_list/1, filter/2,
intersection/2, and subtract/2.
maps:foreach/2 allows iteration over a map without
returning any value.

The pretty printer for floating point number have been
changed to make it easier to see if the integer part of
the number has been rounded. After the change the digit
that may have been rounded always appears last or just
before the exponent character (e or E). This is
accomplished by always printing the number using
scientific notation if it is so large that the integer
part could be rounded.
