Erlang/OTP 17.0-rc1 has been released.

This is an alpha release, which will be followed by a planned beta release
about a month later and a final
OTP 17.0 product release in the end of March 26, 2014.
Between the alpha and beta and final release there will be new updates of
the master branch with corrections
and minor new features. Occasionally there might be new tags which we in
that
case will communicate and ask you to test.

Erlang/OTP 17.0 is a new major release with new features, quite a few
(characteristics) improvements,
as well as some incompatibilities. See the README file and the
documentation for more details.

We would like to ask you to download and test the alpha release and send us
your feedback as soon as possible,
so that we can make the necessary corrections before OTP 17.0-rc2 and OTP
17.0, respectively.
The release contains many changes; thus, some unexpected incompatibilities
or issues may have slipped through
our tests. Please try to build and run your current products/applications
and let us know about any problems.

Note! The new datatype MAP is not properly documented yet but the EEP 43
http://www.erlang.org/eeps/eep-0043.html
will provide a good start. Also note that it is a limited implementation of
maps implemented so far:

    - no variable keys are allowed
    - native code can not be generated for modules using maps

Some other highlights of the release are:

    - Maps, a new dictionary data type (experimental)
    - A more natural mapping from ASN.1 OCTET STRING and BIT STRING to
Erlang types,
      and other ASN.1 improvements and optimizations
    - The {active, N} socket option for TCP, UDP, and SCTP
    - A new (optional) scheduler utilization balancing mechanism
    - Migration of memory carriers has been enabled by default on all ERTS
internal
      memory allocators
    - Increased garbage collection tenure rate
    - Experimental "dirty schedulers" functionality
    - Funs can now be given names
    - Miscellaneous unicode support enhancements
    - A new, semantic version scheme for OTP and its applications
