The new Digsby is here!  We just released Build 32 (r17926) which is the culmination of a massive effort to improve performance, improve connectivity, fix most of the remaining bugs, and add some new functionality to boot. Major changes in this release include:

• RAM Usage: We optimized from the ground up and fixed memory leaks to lower RAM usage by almost 75%.  This has been the number one complaint since our launch and we are proud to introduce this massive improvement.
• Performance: User interface elements draw twice as fast for better performance. We have made changes to the architecture that will improve GUI responsiveness and CPU utilization across the board.
• Connectivity: Every IM protocol automatically tries multiple connection methods and ports to improve the odds of getting through restrictive firewalls and proxy servers.
• LinkedIn: Digsby now supports LinkedIn in addition to the other social networks.  Functionality includes a full newsfeed, alerts when new messages arrive, and the ability to set status right from Digsby.
• Bug Fixes: We have fixed hundreds of bugs, making Digsby more stable than ever.  There have been almost 3,000 revisions in our codebase since the last release so there are too many fixes to list in our changelog.
