+ <p>
+ Changed <c>erlang:apply/2</c> to raise a <c>badarg</c>
+ exception if the second argument is not a proper list.
+ Previous behavior was a misleading <c>undef</c>
+ exception.</p>
+ <p>
+ Own Id: OTP-14490 Aux Id: ERL-432 </p>

+ <item>
+ <p>On macOS, <c>crypto</c> would crash if <c>observer</c>
+ had been started before <c>crypto</c>. On the beta for
+ macOS 10.13 (High Sierra), <c>crypto</c> would crash.
+ Both of those bugs have been fixed.</p>
+ <p>
+ Own Id: OTP-14499 Aux Id: ERL-251 ERL-439 </p>
+ </item>
+ <item>
+ <p>
+ Fixed bug in enif_whereis_pid/port that could cause heap
+ corruption in rare cases.</p>
+ <p>
+ Own Id: OTP-14523</p>
+ </item>
+ <item>
+ <p>
+ Fix so that trace messages generated when in a dirty nif
+ are flushed correctly when the dirty nif is done
+ executing.</p>
+ <p>
+ Own Id: OTP-14538</p>
+ </item>
+ <item>
+ <p>

+ the shell.</p>
+ <p>
+ Own Id: OTP-14549 Aux Id: PR1536 </p>
+ </item>
+ <item>
+ <p>
+ Upgraded the ERTS internal PCRE library from version 8.40
+ to version 8.41. See <url
+ href="http://pcre.org/original/changelog.txt">http://pcre.org/original/changelog.txt</url>
+ for information about changes made to PCRE. This library
+ implements major parts of the <seealso
+ marker="stdlib:re"><c>re</c></seealso> regular
+ expressions module.</p>
+ <p>
+ Own Id: OTP-14574</p>
+ </item>
+ <item>
+ <p>
+ Fixed a bug causing <c>statistics(runtime)</c> to produce
+ negative values and a bug in
+ <c>statistics(wall_clock)</c> causing it to produce
+ values one second too long.</p>
+ <p>
+ <c>statistics(runtime)</c> now also use
+ <c>getrusage()</c> as source when available preventing
+ the returned value from wrapping as frequent as before.</p>
+ <p>
+ Own Id: OTP-14597 Aux Id: ERL-465 </p>

+ <p>
+ Own Id: OTP-14612</p>
+ </item>
+ <item>
+ <p>A warning that the compiler may optimize away atoms
+ have been added to the documentation of
+ <c>list_to_existing_atom/1</c> and
+ <c>binary_to_existing_atom/2</c>.</p>

+ <list>
+ <item>
+ <p>Lock counting can now be fully toggled at runtime in
+ the lock counting emulator (<c>-emu_type lcnt</c>).
+ Everything is enabled by default to match the old
+ behavior, but specific categories can be toggled at will
+ with minimal runtime overhead when disabled. Refer to the
+ documentation on <c>lcnt:rt_mask/1</c> for details.</p>
+ <p>
+ Own Id: OTP-13170</p>
+ </item>
+ <item>
+ <p>The <c>zlib</c> module has been refactored and all its
+ operations will now yield appropriately, allowing them to
+ be used freely in concurrent applications.</p> <p>The
+ following functions have been deprecated, but will not
+ produce compiler warnings until OTP 21:
+ <c>zlib:adler32</c>, <c>zlib:crc32</c>,
+ <c>zlib:inflateChunk</c>, <c>zlib:getBufSize</c>,
+ <c>zlib:setBufSize</c>.</p> <p>The behavior of throwing
+ an error when a dictionary is required for decompression
+ has also been deprecated. Refer to the documentation on
+ <c>inflateSetDictionary/2</c> for details.</p>
+ <p>
+ Own Id: OTP-14185</p>
+ </item>
+ <item>
+ <p><c>lcnt:collect</c> and <c>lcnt:clear</c> will no
+ longer block all other threads in the runtime system.</p>
+ <p>
+ Own Id: OTP-14412</p>
+ </item>
+ <item>
+ <p>Add <c>erlang:iolist_to_iovec/1</c>, which converts an
+ iolist() to an erlang:iovec(), which suitable for use
+ with <c>enif_inspect_iovec</c>.</p>
+ <p>
+ Own Id: OTP-14520</p>
+ </item>
+ <item>
+ <p>When provided with bad arguments, the <c>zlib</c>
+ module will now raise named exceptions instead of just
+ <c>badarg</c>. For example, <c>not_initialized</c> when
+ using <c>zlib:inflate/2</c> with an uninitialized
+ stream.</p>
+ <p>
+ Own Id: OTP-14527</p>
+ </item>
+ <item>
+ <p>
+ <c>erlang:halt/2</c> allows any Unicode string as slogan
+ for the crash dump.</p>
+ <p>
+ Own Id: OTP-14553</p>

+ <item>
+ <p>Add new nif API functions for managing an I/O Queue.

+ A timer internal bit-field used for storing scheduler id
+ was too small. As a result, VM internal timer data
+ structures could become inconsistent when using 1024
+ schedulers on the system. Note that systems with less
+ than 1024 schedulers are not effected by this bug.</p>
+ <p>
+ This bug was introduced in ERTS version 7.0 (OTP 18.0).</p>
+ <p>

+ </item>
+ <item>
+ <p>
+ Fixed bug in <c>binary_to_term</c> and
+ <c>binary_to_atom</c> that could cause VM crash.
+ Typically happens when the last character of an UTF8
+ string is in the range 128 to 255, but truncated to only
+ one byte. Bug exists in <c>binary_to_term</c> since ERTS
+ version 5.10.2 (OTP_R16B01) and <c>binary_to_atom</c>
+ since ERTS version 9.0 (OTP-20.0).</p>

+ Fix performance bug in pre-allocators that could cause
+ them to permanently fall back on normal more expensive
+ memory allocation. Pre-allocators are used for quick
+ allocation of short lived meta data used by messages and
+ other scheduled tasks. Bug exists since OTP_R15B02.</p>

+ <p>
+ Fixed bug in operator <c>bxor</c> causing erroneuos
+ result when one operand is a big <em>negative</em>
+ integer with the lowest <c>N*W</c> bits as zero and the
+ other operand not larger than <c>N*W</c> bits. <c>N</c>
