<section><title>Fixed Bugs and Malfunctions</title>
<list>
<item>
<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>
<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>

corruption in rare cases.</p>
<p>
Own Id: OTP-14523</p>

<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>

Fixed small memory leak that could occur when sending to

<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>
<item>
<p>Add new nif API functions for managing an I/O Queue.
The added functions are:</p> <list type="bulleted">

<p>
Compiling an ASN.1 module using the option {n2n,
EnumTypeName} when EnumTypeName contains a hypen like for
example Cause-Misc caused syntax errors when compiling
the generated Erlang code. This is now corrected.</p>

<p>Fail labels on guard BIFs weren't taken into account
during an optimization pass, and a bug in the validation
pass sometimes prevented this from being noticed when a
fault occurred.</p>

Own Id: OTP-14522 Aux Id: ERIERL-48 </p>

<p>
When compiling from Core Erlang, an 'apply' with a nested
apply in the function position would be treated as an
invalid call. Corrected. (Thanks to Mikael Pettersson for
reporting this bug.)</p>
<p>
Own Id: OTP-14526</p>

<item>
<p>Fixed checking of binary matching in the
<c>beam_validator</c> module to ensure that potential
compiler bugs are found at compile-time instead as
emulator crash at run-time.</p>
<p>
Own Id: OTP-14591</p>
