As you may know, Sublime Text 3 is a lightweight, multi-platform, text editor. It is installable on Ubuntu, Windows and Mac OS X. Sublime Text has a proprietary licence, but the application can also be used for free, without needing to do reverse engineer hacking. Those who want to support the developer’s work can buy Sublime Text for $70.

Sublime Text 3 is still a beta, the latest version available being Sublime Text 3 Build 3083, which comes with the below changes:
- Fixed high CPU usage caused by a corrupt index. This was was occuring for some users upgrading from 3065
- Added setting index_workers to control the number of threads used for file indexing. By default the number of threads is based on the number of CPU cores. By setting index_workers to 1 or 2, indexing will be slower, but less intrusive
- Fixed a crash when showing the Command Palette with an empty .sublime-build file
- Tab completion no longer completes numbers. Edit/Show Completions can still be used for this
