**Highlights: **

• 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. The self extracting installer can be found here.
• 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 implementation.
