Erlang/OTP R16A has been released. This is a beta release before the R16B
product release on February 27:th.

OTP R16 i a new major release with a number of new features,
characteristics and also some minor incompatibilities.
We encourage you to build and test your applications using this release and
report unexpected problems to us.
See the readme file and the documentation for more details.

Some of the highlights are:

   - Optimized handling of processes in the VM
      - New internal process table allowing for parallel reads and writes
      - optimized run queue management
      - optimized process state changes
   - "Non-blocking" code loading
   - New internal port table, and rewrite of scheduling of port tasks.
   - Dynamic allocation of port structures, allowing the default for
   maximum ports to be raised to 65536 (from 1024)
   - Support for UTF-8 encoded Unicode characters in source files.
   - Inets application: The http client now support HTTPS through a proxy
   - Asn1 application: Major cleanup of back ends and optimizations of
   mainly decode for PER and UPER.
   - The experimental features parameterized modules and packages are
   removed. An alternative compatible solution
   for parameterized modules is provided here
   - All built in functions BIF's (even if they are implemented in C as
   part of the VM) are now visible in the
   source code of the module they belong to, including their type specs.
   - The Wx application now compiles and is usable with the
   unstable development branch of wxWidgets-2.9.
   This means that wx can now be built on 64 bit MacOsX as well.
