If you've been using the dev builds during the week, then this is the version you've already got, otherwise, the major new features are:
- Sparkle for automatic updates on OS X, and more robust update notification on other platforms.
- A command line tool, subl for working from the OS X command prompt.
- A shadow is drawn on the file when it's clipped from the left or right, giving a visual indicator that you're not seeing everything, and separating the minimap from the main file.
- The first line of a file can be used to determine the syntax to apply to it.
- Lots more!
With regards to the dev builds, everyone who was using the dev channel during the week has now been moved onto the stable channel, with respect to update notifications. From the next available dev build, these will be separated. I'll post a notification on the forum when the next dev build is available.
