+ <section><title>Fixed Bugs and Malfunctions</title>
+ <list>
+ <item>
+ <p>
+ Fixed a <c>configure</c> test for <c>libz</c> internals
+ that unintentionally caused various native code in OTP to
+ link against <c>libz</c>. Under certain circumstances
+ this caused the build of OTP to fail.</p>
+ <p>
+ Own Id: OTP-14840 Aux Id: ERL-529 </p>
+ </item>
+ <item>
+ <p>
+ File names containing unicode codepoints larger than 255
+ were not correctly encoded in stack traces.</p>
+ <p>
+ Own Id: OTP-14847 Aux Id: ERL-544 </p>
+ </item>
+ <item>
+ <p>
+ Fix HiPE bug for binary constructs like
+ <c>&lt;&lt;X/utf8&gt;&gt;</c> which could in rare cases
+ cause faulty results or VM crash.</p>
+ <p>
+ This fix affects both the <c>hipe</c> compiler and
+ <c>erts</c> runtime in an <em>incompatible</em> way. Old
+ hipe compiled files need to be recompiled to load and run
+ properly as native.</p>
+ <p>
+ *** POTENTIAL INCOMPATIBILITY ***</p>
+ <p>
+ Own Id: OTP-14850 Aux Id: PR-1664 </p>
+ </item>
+ <item>
+ <p>
+ Fix <c>term_to_binary/2</c> spec for
+ <c>minor_version</c>.</p>
+ <p>
+ Own Id: OTP-14876 Aux Id: ERL-548 </p>
+ </item>
+ <item>
+ <p>
+ Fix bug in erlang:binary_to_integer/2 where invalid
+ characters were not detected for bases larger then 10.
+ e.g. <c>binary_to_integer(&lt;&lt;":"&gt;&gt;, 16)</c>
+ would return 3 and not badarg as it should.</p>
+ <p>
+ Own Id: OTP-14879</p>
+ </item>
+ <item>
+ <p>Fixed bug in <c>float_to_list/2</c> and
+ <c>float_to_binary/2</c> with option <c>decimals</c> that
+ caused a faulty rounding up of the last decimal digit for
+ about 6% of floats with a fraction part.</p>
+ <p>For example, <c>float_to_list(0.145,
+ [{decimals,1}])</c> returned <c>"0.2"</c> instead of
+ <c>"0.1"</c>.</p>
+ <p>
+ Own Id: OTP-14890</p>
+ </item>
+ <item>
+ <p>
+ Fix bug causing slow hipe execution in modules loaded
+ early during boot or loaded by <c>code:atomic_load</c> or
+ <c>code:finish_loading</c>.</p>
+ <p>
+ Own Id: OTP-14891</p>
+ </item>
+ <item>
+ <p>Fixed a buffer overflow in an internal string
+ formatting function that could be hit if specifying a
+ long floating-point format specifier to
+ <c>erts_sprintf</c> or similar.</p>
+ <p>
+ Own Id: OTP-14920</p>
+ </item>
+ <item>
+ <p><c>erlang:iolist_to_iovec/1</c> and
+ <c>enif_inspect_iovec</c> will no longer fail when
+ provided with binaries that have been matched-out on a
+ non-byte boundary.</p>
+ <p>
+ Own Id: OTP-14921</p>
+ </item>
+ <item>
+ <p><c>iolist_to_binary/1</c> and
+ <c>erlang:iolist_to_iovec/1</c> will now badarg if
+ supplied with a bitstring (without a list).</p>
+ <p>
+ Own Id: OTP-14926</p>
+ </item>
+ <item>
+ <p>
+ Reject loading modules with names containing directory
+ separators ('/' or '\' on Windows).</p>
+ <p>
+ Own Id: OTP-14933 Aux Id: ERL-564, PR-1716 </p>
+ </item>
+ <item>
+ <p>
+ Fix potential dead-lock when the tracer process dies
+ while a the traced process is running on a dirty
+ scheduler.</p>

+ stats, full info for process causing out-of-mem during
+ GC, more port related info, and dirty scheduler info.</p>
