Check out the git tag OTP-18.0.2, and build a full OTP system
including documentation. Apply one or more applications from this
build as patches to your installation using the 'otp_patch_apply'
tool. For information on install requirements, see descriptions for
each application version below.
The erts-7.0.2 application can be applied independently of other
applications on a full OTP 18 installation.

OTP-12889 Application(s): erts
Related Id(s): seq12885
A process could end up in an inconsistent half exited
state in the runtime system without SMP support. This
could occur if the processes was traced by a port that
it also was linked to, and the port terminated
abnormally while handling a trace message for the
This bug has always existed in the runtime system
without SMP support, but never in the runtime system
with SMP support.
OTP-12894 Application(s): erts
Removed unnecessary copying of data when retrieving
corrected Erlang monotonic time.
OTP-12895 Application(s): erts
*** POTENTIAL INCOMPATIBILITY ***
Changed default OS monotonic clock source chosen at
build time. This in order to improve performance. The
behavior will now on most systems be that (both OS and
Erlang) monotonic time stops when the system is
If you prefer that monotonic time elapse during suspend
of the machine, you can pass the command line argument
to configure when building Erlang/OTP. The
configuration stage will try to find such a clock
source, but might not be able to find it. Note that
there might be a performance penalty associated with
such a clock source.
OTP-12896 Application(s): erts
erlang:system_info(end_time) returned a faulty value on
--- Improvements and New Features ---
OTP-12892 Application(s): erts
The configure command line argument
--enable-gettimeofday-as-os-system-time has been added
which force usage of gettimeofday() for OS system time.
This will improve performance of os:system_time() and
os:timestamp() on MacOS X, at the expense of worse
accuracy, resolution and precision of Erlang monotonic
time, Erlang system time, and OS system time.
