+ <list>
+ <item>
+ <p>
+ Fix HiPE debug lock checking on OS X 64bit</p>
+ <p>
+ Position-independent code is mandatory on OS X. We use
+ r11 as an intermediate register to fill
+ BIF_P-&gt;hipe.bif_callee. This fixes the following error
+ when doing `make debug FLAVOR=smp`:</p>
+ <p>
+ clang -cc1as: fatal error: error in backend: 32-bit
+ absolute addressing is not supported in 64-bit mode</p>
+ <p>
+ Own Id: OTP-12188</p>
+ </item>
+ <item>
+ <p>
+ Fix race bug that could cause VM crash in
+ <c>erlang:port_get_data/1</c> if the port was closed by a
+ concurrent process. Also fix fatal bug if
+ <c>port_set_data/2</c> is called with a non-immediate
+ data term. Both bugs exist since R16B01.</p>
+ <p>
+ Own Id: OTP-12208</p>
+ </item>
+ <item>
+ <p>
+ Correct make variable SSL_DED_LD_RUNTIME_LIBRARY_PATH
+ when erl_xcomp_sysroot ends with a slash.</p>
+ <p>
+ Own Id: OTP-12216 Aux Id: seq12700 </p>
+ </item>
+ <item>
+ <p>
+ Fix two cases of unreachable code caused by false use of
+ assigment operators.</p>
+ <p>
+ Own Id: OTP-12222</p>
+ </item>
+ <item>
+ <p>
+ Fix bug when hipe compiled code makes tail call to a BIF
+ that disables GC while trapping (sush as binary_to_list,
+ list_to_binary, binary_to_term, term_to_binary).</p>
+ <p>
+ Own Id: OTP-12231</p>
+ </item>
+ <item>
+ <p>
+ Fix bug when a migrated empty memory carrier is reused
+ just before it should be destroyed by the thread that
+ created it.</p>
+ <p>
+ Own Id: OTP-12249</p>
+ </item>
+ <item>
+ <p>
+ Prevents compile-time errors in NIFs, when the compiler
+ is instructed to treat missing field initializers as
+ errors, by adding an initializer for the new options
+ field which was added to ErlNifEntry for 17.3.</p>
+ <p>
+ Own Id: OTP-12266</p>
+ </item>
+ <item>
+ <p>
+ Fixed CPU topology detection on FreeBSD systems where
+ Erlang/OTP is compiled by new C compilers (including, but
+ possibly not limited to, gcc 4.9 and clang).</p>
+ <p>
+ Own Id: OTP-12267</p>
+ </item>
+ <item>
+ <p>
+ Use C99 function isfinite() instead of finite() when
+ available on non GCC compilers.</p>
+ <p>
+ Own Id: OTP-12268</p>
+ </item>
+ <item>
+ <p>
+ Fix bug on windows where an incorrect number of links
+ could be returned when doing file:read_file_info on a
+ directory.</p>
+ <p>
+ Own Id: OTP-12269</p>
+ </item>
+ <item>
+ <p>
+ Fix rare bug when purging module on VM started with
+ +Meamin.</p>
+ <p>
+ Own Id: OTP-12273</p>
+ </item>
+ <item>
+ <p>
+ Repair run_erl terminal window size adjustment sent from
+ to_erl. This was broken in OTP 17.0 which could lead to
+ strange cursor behaviour in the to_erl shell.</p>
+ <p>
+ Own Id: OTP-12275 Aux Id: seq12739 </p>
+ </item>
+ <item>
+ <p>
+ Fixed bug on windows causing gen_tcp/udp to return an
+ error when given an fd to work with.</p>
+ <p>
+ Own Id: OTP-12289</p>
+ </item>
+ <item>
+ <p>
+ Fix various internal erts issues where negating a signed
+ integer in C would trigger undefined behavior. This fixes
+ issues when dividing with bignums and list_to_integer.</p>
+ <p>
+ Own Id: OTP-12290</p>
+ </item>
+ <item>
+ <p>
+ When flushing output to stdout on windows, the emulator
+ could sometimes hang indefinitely waiting for the flush
+ to complete. This has been fixed.</p>
+ <p>
+ Own Id: OTP-12291</p>
+ </item>
+ <item>
+ <p>
+ Fix so that non-smp emulators with dirty scheduler
+ support shows the correct number of dirty schedulers when
+ calling erlang:system_info(system_version).</p>
+ <p>
+ Own Id: OTP-12295</p>
+ </item>
+ <item>
+ <p>
+ Add <c>nif_version</c> to <c>erlang:system_info/1</c> in
+ order to get the NIF API version of the runtime system in
+ a way similar to <c>driver_version</c>.</p>
+ <p>
+ Own Id: OTP-12298</p>
+ </item>
+ <item>
+ <p>
+ Fix bug that could cause the return value from dirty NIF
+ with zero arity to be treated as garbage, leading to VM
+ crash.</p>
+ <p>
+ Own Id: OTP-12300</p>
+ </item>
+ <item>
+ <p>
+ Improve allocation carrier migration search logic. This
+ will reduce the risk of failed migrations that could lead
+ to excess memory consumption. It will also improve smp
+ performance due to reduced memory contention on the
+ migration pool.</p>

+
+ <section><title>Improvements and New Features</title>
+ <list>
+ <item>
+ <p>Introduced support for eager check I/O.</p>
+ <p>By default eager check I/O will be disabled, but this
+ will most likely be changed in OTP 18. When eager check
+ I/O is enabled, schedulers will more frequently check for
+ I/O work. Outstanding I/O operations will however not be
+ prioritized to the same extent as when eager check I/O is
+ disabled.</p>
+ <p>Eager check I/O can be enabled using the <c>erl</c>
+ command line argument: <seealso
+ marker="erl#+secio"><c>+secio true</c></seealso></p>
+ <p>Characteristics impact when enabled:</p> <list>
+ <item>Lower latency and smoother management of externally
+ triggered I/O operations.</item> <item>A slightly reduced
+ priority of externally triggered I/O operations.</item>
+ </list>
+ <p>
+ Own Id: OTP-12117</p>
+ </item>
+ <item>
+ <p>
+ Fix erts .app-file</p>
+ <p>
+ Own Id: OTP-12189</p>
+ </item>
+ <item>
+ <p>
+ Add configure option --with-ssl-incl=PATH to support
+ OpenSSL installations with headers and libraries at
+ different places.</p>
+ <p>
+ Own Id: OTP-12215 Aux Id: seq12700 </p>
+ </item>
+ <item>
+ <p>
+ Optimization of atomic memory operations with release
+ barrier semantics on 32-bit PowerPC when using the
+ implementation included in OTP.</p>
+ <p>
+ Own Id: OTP-12250</p>
+ </item>
+ <item>
+ <p>
+ Minor adjustment of scheduler activation code making sure
+ that an activation of a scheduler is not prevented by its
+ run-queue being non-empty. (Thanks to Songlu Cai)</p>
+ <p>
+ Own Id: OTP-12287</p>
+ </item>
+ <item>
+ <p>
+ Improved support for atomic memory operations provided by
+ the <url
+ href="https://github.com/ivmai/libatomic_ops/"><c>libatomic_ops</c></url>
+ library. Most importantly support for use of native
+ double word atomics when implemented by
+ <c>libatomic_ops</c> (for example, implemented for ARM).</p>
+ <p>
+ The <seealso
+ marker="doc/installation_guide:INSTALL#Advanced-configuration-and-build-of-ErlangOTP_Configuring_Atomic-Memory-Operations-and-the-VM"><c>$ERL_TOP/HOWTO/INSTALL.md</c></seealso>
+ document now also more clearly describes when you want to
+ build together with a <c>libatomic_ops</c> installation.</p>
+ <p>
+ Own Id: OTP-12302</p>
+ </item>
+ <item>
+ <p>
+ Add configure option --with-ssl-rpath to control which
+ runtime library path to use for dynamic linkage toward
+ OpenSSL.</p>
+ <p>
+ Own Id: OTP-12316 Aux Id: seq12753 </p>
+ </item>
+ <item>
+ <p>
+ Added systemd notify support to epmd</p>
+ <p>
+ Own Id: OTP-12321</p>
