The old time API is based on erlang:now/0. The major issue with
erlang:now/0 is that it was intended to be used for so many
unrelated things. This tied these unrelated operations together
and unnecessarily caused performance, scalability as well as
accuracy, and precision issues for operations that do not need
to have such issues. The new API spreads different functionality
over multiple functions in order to improve on this.
The new API consists of a number of new BIFs:
- erlang:convert_time_unit/3
- erlang:monotonic_time/0
- erlang:monotonic_time/1
- erlang:system_time/0
- erlang:system_time/1
- erlang:time_offset/0
- erlang:time_offset/1
- erlang:timestamp/0
- erlang:unique_integer/0
- erlang:unique_integer/1
- os:system_time/0
- os:system_time/1
and a number of extensions of existing BIFs:
- erlang:monitor(time_offset, clock_service)
- erlang:system_flag(time_offset, finalize)
- erlang:system_info(os_monotonic_time_source)
- erlang:system_info(time_offset)
- erlang:system_info(time_warp_mode)
- erlang:system_info(time_correction)
- erlang:system_info(start_time)
See the "Time and Time Correction in Erlang" chapter of the
ERTS User's Guide for more information.

If file:name_native_encoding() returns 'utf8', any arguments following
the -run option are assumed to be encoded in UTF-8. -eval should
treat is argument the same way.

This is a workaround for init:restart.
The root problem is that delete/purge_module does not
clean up internal hipe bookkeeping (hipe_mfa_info's)
properly.
Symptom: Execution of deallocated beam code.

Putenv and getenv needs to convert to the proper environment
strings in Unicode depending on platform and user settings for filename
encoding. Also erlexec needs to pass environment strings in an appropriate
way for kernel to pick up. All environment strings on the command
line, as well as home directory, is now passed in UTF8 on windows
and in whatever encoding you have on Unix, kernel tries to convert all
parameters and environments from UTF8 before making strings.

A number of memory allocation optimizations have been implemented. Most
optimizations reduce contention caused by synchronization between
threads during allocation and deallocation of memory. Most notably:
* Synchronization of memory management in scheduler specific allocator
instances has been rewritten to use lock-free synchronization.
* Synchronization of memory management in scheduler specific
pre-allocators has been rewritten to use lock-free synchronization.
* The 'mseg_alloc' memory segment allocator now use scheduler specific
instances instead of one instance. Apart from reducing contention
this also ensures that memory allocators always create memory
segments on the local NUMA node on a NUMA system.

In embedded mode, all on_load handlers will be called after
loading all modules but before starting any servers. Therefore,
if an on_load handler calls any function in the code module that
calls the code server (such as code:priv_dir/1), there will be a
deadlock because the code server has not yet been started.
Fix this problem by invoking the on_load handlers after
having started most servers in the kernel application.

This is the public interface of prim_zip:open/3,
which has been used in earlier releases by both
erl_prim_loader and escript. The new function
can be used as a replacement for the undocumented
function escript:foldl/3 that is likely to be
removed without further notice.
The error handling of prim_zip:open/3 (and
prim_zip:foldl/3) has been improved in order to
better suite a public interface. For example it
could happen that a file or a zlib port could be
left open in some errors cases.
The documentation of the FileSpec parameter to
zip:create/3 has been updated to show that
file info can be explicitly specified. A FileSpec
may contain {Filename, binary(), #file_info{}}
elements. The function zip:create/3 was already
prepared to partly support this, but now after
a few minor fixes it is fully supported.
