Erlang/OTP R15B has been released.

This is a new major release of Erlang/OTP

This is a release with many interesting new features:


   - Line number and filename information are now included in exception
   backtraces. This information will be pretty-printed in the shell and used
   in crash reports etc. In practice it will be much easier to find where
   something failed.
   - The driver interface has been changed to enable 64-bit aware drivers.
   Most importantly the return types for ErlDrvEntry callbacks 'call' and
   'control' has been changed which require drivers to be changed.
   - New in this release is the support for 64 bit  Windows.
   - CommonTest hooks are now in a final supported version.
   - There is a new GUI tool in the observer application which integrates
   pman, etop, appmon and tv into one tool. The tool does also contain
   functions for activating tracing in an easy way.
   - The Erlang distribution can now be run over the new SSL
