— HIGHLIGHTS ———————————————————-

OTP-8217 == erts stdlib compiler ==

The module binary from EEP31 (and EEP9) is implemented.

OTP-8485 == common_test ==

It is now possible for the user to provide specific callback
modules that handle test configuration data, so that data on
arbitray form can be accessed (e.g. by reading files or by
communicating with a configuration server process). Two
default callback modules have been introduced in Common Test:
ct_config_plain and ct_config_xml. The former is used to
handle the traditional Common Test configuration files (with
terms on key-value tuple form) and the latter to handle
configuration data on XML representation.

OTP-8555 == erts ==

New NIF features:

Send messages from a NIF, or from thread created by NIF, to
any local process (enif_send)

Store terms between NIF calls (enif_alloc_env,
enif_make_copy)

Create binary terms with user defined memory management
(enif_make_resource_binary)

And some incompatible changes made to the API. For more
information see the warning text in erl_nif(3).

OTP-8623 == compiler erts hipe stdlib ==

Receive statements that can only read out a newly created
reference are now specially optimized so that it will execute
in constant time regardless of the number of messages in the
receive queue for the process. That optimization will benefit
calls to gen_server:call(). (See gen:do_call/4 for an example
of a receive statement that will be optimized.)

OTP-8650 == common_test ==

The run_test script has been replaced by a program (with the
same name) which can be executed without explicit
installation. The start flags are the same as for the legacy
start script.

OTP-8706 == erts hipe tools ==

eprof has been reimplemented with support in the Erlang
virtual machine and is now both faster (i.e. slows down the
code being measured less) and scales much better. In
measurements we saw speed-ups compared to the old eprof
ranging from 6 times (for sequential code that only uses one
scheduler/core) up to 84 times (for parallel code that uses 8
cores).

Note: The API for the eprof has been cleaned up and extended.
See the documentation.
