+ Added missing release notes for OTP-14491 ("performance
+ bug in pre-allocators") which was included in erts-9.0.1
+ (OTP-20.0.1).</p>
+ <p>
+ Own Id: OTP-14494</p>
+ </item>
+ <item>
+ <p>Fixed a bug that prevented TCP sockets from being
+ closed properly on send timeouts.</p>
+ <p>
+ Own Id: OTP-14509</p>
+ </item>
+ <item>
+ <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>
+ is an integer of 1 or larger and <c>W</c> is 32 or 64
+ depending on word size.</p>

+ Fixed a bug in gen_tcp:send where it never returned when
+ repeatedly called on a remotely closed TCP socket.</p>
+ <p>
+ Own Id: OTP-13939 Aux Id: ERL-193 </p>
+ </item>
+ <item>
+ <p>
+ Fixed segfault that could happen during cleanup of
+ aborted erlang:port_command/3 calls. A port_command is
+ aborted if the port is closed at the same time as the
+ port_command was issued. This bug was introduced in
+ erts-8.0.</p>
+ <p>
+ Own Id: OTP-14481</p>
+ </item>
+ <item>
+ <p>
+ Fixed implementation of <c>statistics(wall_clock)</c> and
+ <c>statistics(runtime)</c> so that values do not
+ unnecessarily wrap due to the emulator. Note that the
+ values returned by <c>statistics(runtime)</c> may still
+ wrap due to limitations in the underlying functionality
+ provided by the operating system.</p>
+ <p>
+ Own Id: OTP-14484</p>
+ </item>
+ <item>
+ <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.
