<p>This document describes the changes made to the ERTS application.</p>
+<section><title>Erts 8.2</title>
+
+ <section><title>Fixed Bugs and Malfunctions</title>
+ <list>
+ <item>
+ <p>
+ Fixed <c>configure</c> failures on MacOSX. Most important
+ <c>clock_gettime()</c> was detected when building for
+ MacOSX - El Capitan using XCode 8 despite it is not
+ available until MacOSX - Sierra.</p>
+ <p>
+ Own Id: OTP-13904 Aux Id: ERL-256 </p>
+ </item>
+ <item>
+ <p>
+ <c>code:add_pathsa/1</c> and command line option
+ <c>-pa</c> both revert the given list of directories when
+ adding it at the beginning of the code path. This is now
+ documented.</p>
+ <p>
+ Own Id: OTP-13920 Aux Id: ERL-267 </p>
+ </item>
+ <item>
+ <p>
+ Fix a compilation error of erts in OpenBSD related to the
+ usage of the __errno variable.</p>
+ <p>
+ Own Id: OTP-13927</p>
+ </item>
+ <item>
+ <p>
+ Fixed so that when enabling tracing on a process that had
+ an invalid tracer associated with it, the new tracer
+ overwrites the old tracer. Before this fix, calling
+ erlang:trace/3 would behave as if the tracer was still
+ alive and not apply the new trace.</p>
+ <p>
+ This fault was introduced in ERTS 8.0.</p>
+ <p>
+ Own Id: OTP-13928</p>
+ </item>
+ <item>
+ <p>
+ Fix parsing of <c>-profile_boot 'true' | 'false'</c></p>
+ <p>
+ Own Id: OTP-13955 Aux Id: ERL-280 </p>
+ </item>
+ <item>
+ <p>
+ A slight improvement of <c>erlang:get_stacktrace/0</c>
+ for exceptions raised in hipe compiled code. Beam
+ compiled functions in such stack trace was earlier
+ replaced by some unrelated function. They are now instead
+ omitted. This is an attempt to reduce the confusion in
+ the absence of a complete and correct stack trace for
+ mixed beam and hipe functions.</p>
+ <p>
+ Own Id: OTP-13992</p>
+ </item>
+ <item>
+ <p> Correct type declaration of match specification head.
+ </p>
+ <p>
+ Own Id: OTP-13996</p>
+ </item>
+ <item>
+ <p>
+ HiPE code loading failed for x86_64 if gcc was configured
+ with <c>--enable-default-pie</c>. Fixed by disabling PIE,
+ if needed for HiPE, when building the VM.</p>
+ <p>
+ Own Id: OTP-14031 Aux Id: ERL-294, PR-1239 </p>
+ </item>
+ <item>
+ <p>
+ Faulty arguments could be presented on exception from a
+ NIF that had rescheduled itself using
+ <c>enif_schedule_nif()</c>.</p>
+ <p>
+ Own Id: OTP-14048</p>
+ </item>
+ <item>
+ <p>
+ The runtime system could crash if a garbage collection on
+ a process was performed immediately after a NIF had been
+ rescheduled using <c>enif_schedule_nif()</c>.</p>
+ <p>
+ Own Id: OTP-14049</p>
+ </item>
+ <item>
+ <p>
+ A reference to purged code could be left undetected by
+ the purge operation if a process just had rescheduled a
+ NIF call using <c>enif_schedule_nif()</c> when the
+ process was checked. This could cause a runtime system
+ crash.</p>
+ <p>
+ Own Id: OTP-14050</p>
+ </item>
+ <item>
+ <p>Fixed a number of dirty scheduler related bugs:</p>
+ <list> <item><p>Process priority was not handled correct
+ when scheduling on a dirty scheduler.</p></item>
+ <item><p>The runtime system could crash when an exit
+ signal with a compound exit reason was sent to a process
+ executing on a dirty scheduler.</p></item> <item><p>The
+ runtime system crashed when call tracing a process
+ executing on a dirty scheduler.</p></item> <item><p>A
+ code purge operation could end up hanging forever when a
+ process executed on a dirty scheduler</p></item> </list>
+ <p>
+ Own Id: OTP-14051</p>
+ </item>
+ <item>
+ <p>
+ Fixed a number of bugs that caused faulty stack-traces to
+ be created on exception when a process was traced.</p>

+ <section><title>Improvements and New Features</title>
+ <list>
+ <item>
+ <p>
+ Fix minor soft purge race bug that could incorrectly
+ trigger code_server to load new code for the module if
+ the soft purge failed and no current version of the
+ module existed.</p>
+ <p>
+ Own Id: OTP-13925</p>
+ </item>
+ <item>
+ <p>
+ To ease troubleshooting, <c>erlang:load_nif/2</c> now
+ includes the return value from a failed call to
+ load/reload/upgrade in the text part of the error tuple.
+ The <c>crypto</c> NIF makes use of this feature by
+ returning the source line where/if the initialization
+ fails.</p>
+ <p>
+ Own Id: OTP-13951</p>
+ </item>
+ <item>
+ <p>
+ New environment variable <c>ERL_CRASH_DUMP_BYTES</c> can
+ be used to limit the size of crash dumps. If the limit is
+ reached, crash dump generation is aborted and the
+ generated file will be truncated.</p>
