Since version 3.0 we've been shipping frequent dev builds, refining Sublime Text for a more polished experience all-around. Those dev builds are now rolling out to everyone as Sublime Text 3.1. The full changelog for 3.1 includes every detail, but the following are some we'd like to highlight:

Lots of improvements for high DPI support on all platforms, including 8k monitor and @3x texture support

Text Rendering

Ligature support, with controls for customizing OpenType features and stylistic sets

Improved text rendering on Windows, now respecting ClearType tuning

Better handling of emojis in the editor control 🎉

Syntax definitions for Git file formats to allow Sublime Text to be a better core.editor

Many of these changes were developed in response to the community's feedback, and in some cases with your help! As may be evident, this dev cycle spent a good amount of time polishing some foundational elements of the editor and making it more robust for use on different configurations and for different purposes.

We've got some exciting things planned for the future, which will further build upon the foundation we've laid with 3.0 and 3.1! If you want to preview the latest changes and help provide feedback during the next dev cycle, install the latest dev build and you'll get notifications as we release new updates.
