Sublime Text 3.0 is now released and it features a refreshed UI theme, new color schemes, and a new icon. Everything has been improved since v2 and includes better performance.
From their release announcement:
Certainly there are big features that 3.0 has: Goto Definition, a new syntax highlighting engine, a new UI, and an expanded API. However the difference is frequently felt in the hundreds of improvements that don’t warrant being featured on their own: spell checking works better, automatic indentation does the right thing more often, word wrapping handles source code better, high DPI screens are properly supported, and Goto Anything is smarter. There’s too much to list, but combined the difference is night and day.
One of the areas I’m especially proud of in Sublime Text 3 is performance: it’s significantly faster than Sublime Text 2 along every axis. Startup is faster, opening files is faster, and scrolling is more efficient. While it’s a much larger application than 2, it feels leaner.
If you’ve purchased a license after 2013 your license is valid for v3 and upgrades are available if you purchased before 2013.
