Sublime Text 3 just dropped the biggest update in nearly a year with build 3103. A handful of bug fixes sprinkled among various fine tuning and even a couple of new bits are included with this build. The official blog post highlights a few things including a new syntax definition format, .sublime-syntax, a new, custom regex engine and a couple of announcements: packages shipped with Sublime Text 3 are now on GitHub and Will Bond, of Package Control fame, has joined the Sublime HQ dev team.
The Sublime Text 3 download page has detailed release notes. If you already have Sublime Text 3 installed, just run the application and it should prompt you to download and update automatically.
