+ The option dupnames did not work as intended in re. When
+ looking for names with {capture, [Name, ...]}, re:run
+ returned a random instance of the match for that name,
+ instead of the leftmost matching instance, which was what
+ the documentation stated. This is now corrected to adhere

+ along with a re:inspect/2 function is also added to

+ Fix bs_get_integer instruction</p>
+ <p>
+ The instruction bs_get_integer could unnecessarily
+ trigger a garbage collection in failure cases which is
+ unwanted or outright dangerous.</p>
+ <p>
+ Ex:</p>
+ <p>
+ &lt;&lt;X:Sz,_/bits&gt;&gt; = &lt;&lt;"some
+ binary"&gt;&gt;</p>
+ <p>
+ Previously, if Sz induced X to a bignum it would reserved
+ memory size this on the heap via a garbage collection
+ before checking if the size could actually match.</p>
+ <p>
+ It will now check the binary size before triggering a
+ collection.</p>

+ <item>
+ <p>
+ Increase garbage collection tenure rate</p>
+ <p>The garbage collector tries to maintain the previous
+ heap block size during a minor gc, i.e. 'need' is not
+ utilized in determining the size of the new heap, instead
+ it relies on tenure and garbage to be sufficiently
+ large.</p>
+ <p>In instances during intense growing with exclusively
+ live data on the heap coupled with delayed tenure,
+ fullsweeps would be triggered directly after a minor gc
+ to make room for 'need' since the new heap would be
+ full.</p>
+ <p>To remedy this, the tenure of terms on the minor heap
+ will always happen (if it is below the high watermark)
+ instead of every other minor gc.</p>
+ <p>Characteristics Impact: Reduced CPU-time spent in
+ garbage collection but may infer delays in collecting
+ garbage from the heap. Tweak 'fullsweep_after' options to
+ increase gc pressure if needed.</p>

+ <p>
+ sendfile no longer uses async threads by default</p>
+ <p>
+ This has been done because a slow client attack is
+ possible if the async thread pool is used. The scenario
+ is:</p>
+ <p>
+ Client does a request for a file and then slowly receives
+ the file one byte at a time. This will eventually fill
+ the async thread pool with blocking sendfile operations
+ and thus starving the vm of all file operations.</p>
+ <p>
+ If you still want to use the async threads pool for
+ sendfile an option to enable it has been introduced.</p>
+ <p>
+ Thanks to Christopher Faulet for identifying this
+ vulnerability.</p>

+ default on Linux when HiPE was enabled when configuring
+ with <c>$ERL_TOP/configure</c>, but not when configuring
+ with <c>$ERL_TOP/otp_build configure</c>. The default is
+ now in both cases not to use floating point exceptions
+ since there still exist unresolved issues with floating

+ A common case is to wrap an argument to

+ The version of the PCRE library Used by Erlang's re
+ module is raised to 8.33 from 7.6. This means, among
+ other things, better Unicode and Unicode Character
+ Properties support. New options connected to PCRE 8.33
+ are also added to the re module (ucd, notempty_atstart,
+ no_start_optimize). PCRE has extended the regular
+ expression syntax between 7.6 and 8.33, why this imposes
+ a potential incompatibility. Only very complicated
+ regular expressions may be affected, but if you know you
+ are using obscure features, please test run your regular
+ expressions and verify that their behavior has not
+ changed.</p>

+ By giving --enable-static-{nifs,drivers} to configure it
+ is now possible to statically linking of nifs and drivers
+ to the main Erlang VM binary. At the moment only the asn1

+ been prepared to be statically linked. For more details
+ see the Installation Guide in the System documentation.</p>

+ Erlang/OTP has been ported to the realtime operating
+ system OSE. The port supports both smp and non-smp
+ emulator. For details around the port and how to started
+ see the User's Guide in the <seealso
+ marker="ose:ose_intro">ose</seealso> application. </p>
+ <p>
+ Note that not all parts of Erlang/OTP has been ported. </p>
+ <p>
+ Notable things that work are: non-smp and smp emulators,
+ OSE signal interaction, crypto, asn1, run_erl/to_erl,
+ tcp, epmd, distribution and most if not all non-os
+ specific functionality of Erlang.</p>
+ <p>
+ Notable things that does not work are: udp/sctp, os_mon,
+ erl_interface, binding of schedulers.</p>

+ <item>
+ <p>
+ Add the {active,N} socket option for TCP, UDP, and SCTP,
+ where N is an integer in the range -32768..32767, to
+ allow a caller to specify the number of data messages to
+ be delivered to the controlling process. Once the
+ socket's delivered message count either reaches 0 or is
+ explicitly set to 0 with inet:setopts/2 or by including
+ {active,0} as an option when the socket is created, the
+ socket transitions to passive ({active, false}) mode and
+ the socket's controlling process receives a message to
+ inform it of the transition. TCP sockets receive
+ {tcp_passive,Socket}, UDP sockets receive
+ {udp_passive,Socket} and SCTP sockets receive
+ {sctp_passive,Socket}. </p>
+ <p>
+ The socket's delivered message counter defaults to 0, but
+ it can be set using {active,N} via any gen_tcp, gen_udp,
+ or gen_sctp function that takes socket options as
+ arguments, or via inet:setopts/2. New N values are added
+ to the socket's current counter value, and negative
+ numbers can be used to reduce the counter value.
+ Specifying a number that would cause the socket's counter
+ value to go above 32767 causes an einval error. If a
+ negative number is specified such that the counter value
+ would become negative, the socket's counter value is set
+ to 0 and the socket transitions to passive mode. If the
+ counter value is already 0 and inet:setopts(Socket,
+ [{active,0}]) is specified, the counter value remains at
+ 0 but the appropriate passive mode transition message is
+ generated for the socket.</p>

+ A new optional scheduler utilization balancing mechanism
+ has been introduced. For more information see the
+ <seealso marker="erl#+sub"><c>+sub</c></seealso> command
+ line argument.</p>
+ <p>
+ Characteristics impact: None, when not enabled. When
+ enabled, changed timing in the system, normally a small
+ overhead due to measuring of utilization and calculating
+ balancing information. On some systems, such as old
+ Windows systems, the overhead can be quite substantial.
+ This time measurement overhead highly depend on the
+ underlying primitives provided by the OS.</p>

+ <p>
+ A call to either the <c>garbage_collect/1</c> BIF or the
+ <c>check_process_code/2</c> BIF may trigger garbage
+ collection of another processes than the process calling
+ the BIF. The previous implementations performed these
+ kinds of garbage collections without considering the
+ internal state of the process being garbage collected. In
+ order to be able to more easily and more efficiently
+ implement yielding native code, these types of garbage
+ collections have been rewritten. A garbage collection
+ like this is now triggered by an asynchronous request
+ signal, the actual garbage collection is performed by the
+ process being garbage collected itself, and finalized by
+ a reply signal to the process issuing the request. Using
+ this approach processes can disable garbage collection
+ and yield without having to set up the heap in a state
+ that can be garbage collected.</p>
+ <p>
+ The <seealso
+ marker="erts:erlang#garbage_collect/2"><c>garbage_collect/2</c></seealso>,
+ and <seealso
+ marker="erts:erlang#check_process_code/3"><c>check_process_code/3</c></seealso>
+ BIFs have been introduced. Both taking an option list as
+ last argument. Using these, one can issue asynchronous
+ requests.</p>
+ <p>
+ <c>code:purge/1</c> and <c>code:soft_purge/1</c> have
+ been rewritten to utilize asynchronous
+ <c>check_process_code</c> requests in order to
+ parallelize work.</p>
+ <p>
+ Characteristics impact: A call to the
+ <c>garbage_collect/1</c> BIF or the
+ <c>check_process_code/2</c> BIF will normally take longer
+ time to complete while the system as a whole wont be as
+ much negatively effected by the operation as before. A
+ call to <c>code:purge/1</c> and <c>code:soft_purge/1</c>
+ may complete faster or slower depending on the state of
+ the system while the system as a whole wont be as much
+ negatively effected by the operation as before.</p>

+ <p>
+ Add sync option to file:open/2.</p>
+ <p>
+ The sync option adds the POSIX O_SYNC flag to the open
+ system call on platforms that support the flag or its
+ equivalent, e.g., FILE_FLAG_WRITE_THROUGH on Windows. For
+ platforms that don't support it, file:open/2 returns
+ {error, enotsup} if the sync option is passed in. Thank
+ to Steve Vinoski and Joseph Blomstedt</p>

+ <p>
+ erlang:binary_to_term will now cost an appropriate amount
+ of reductions and will interrupt (yield) for reschedule
+ if the term is big. This avoids too long schedules when
+ binary_to_term is used. (Thanks to Svante Karlsson for
+ the original patch)</p>
+ <p>
+ Impact: Programs running binary_to_term on large binaries
+ will run more smoothly, but rescheduling will impact the
+ single process performance of the BIF. Single threaded
+ benchmarks might show degraded performance of the BIF,
+ while general system behaviour will be improved.</p>

+ Experimental "dirty scheduler" functionality has been
+ introduced. In order to try the functionality out, you
+ need to pass the command line argument
+ <c>--enable-dirty-schedulers</c> to <c>configure</c> when
+ building the system.</p>
+ <p>
+ Dirty schedulers can currently only be used by NIFs on a
+ system with SMP support. More information can be found in
+ the <seealso
+ marker="erl_nif#dirty_nifs"><c>erl_nif(3)</c></seealso>
+ documentation, the <seealso
+ marker="erl"><c>erl(1)</c></seealso> documentation, and
+ in the git commit comment of commit
+ 'c1c03ae4ee50e58b7669ea88ec4d29c6b2b67c7b'.</p>
+ <p>
+ Note that the functionality is <em>experimental</em>, and
+ <em>not supported</em>. This functionality <em>will</em>
+ be subject to backward incompatible changes. You should
+ <em>not</em> enable the dirty scheduler functionality on
+ production systems. It is only provided for testing.</p>
+ <p>
+ Thanks to Steve Vinoski.</p>

+ Improve reduction cost and yielding of
+ <c>term_to_binary</c>. The reduction cost is increased
+ and garbage collection is disabled during yield.</p>
+ <p>
+ Impact: Improves system responsiveness when
+ <c>term_to_binary</c> is called with large terms without
+ significant degradation of single threaded performance.</p>

+ By default, the system's version of zlib will be used,
