Version 2.3:
New: MultiMarkdown
• CodeKit has switched from the Discount Markdown compiler to MultiMarkdown!
• This brings a ton of features for Markdown, including the ability to import MD files into each other.
• If you use Markdown in CodeKit, you'll want to check the file's settings after updating; none of the old options exist any more.

New: JSON Language Support
• You can now minify and alphabetize JSON files.
• This is opt-in; you have to turn on processing for JSON files in your project. By default, CodeKit won't do anything when you save a JSON file because most of them probably aren't meant to be processed.

New: Apple Watch Support
• Because of course Apple Watch Support.
• Success messages will continue to be logged to the CodeKit window.
• Error messages will now be logged only to your Apple Watch Edition.
• The line number of the syntax error is indicated by haptic feedback. Simply count the number of pulses on your wrist.

Other Interesting Improvements
• The HTTP verbs DELETE and PUT are now supported. You'll still need an external server, but CodeKit will now proxy these requests correctly.
• There is now an «Open With» command if you right-click a file in the list. Works like every «Open With» menu since the dawn of time.
• Literate CoffeeScript is now fully supported. Note: you cannot combine *.litcoffee files with regular Coffee or JS files, but you can combine litcoffee files with each other.
• You can now compile *.sass files with Libsass.
• If your project has a 'bower.json' file, it should now be updated correctly when you install assets.

Hooks
• Bash Hooks can now get a list of all the files that CodeKit processed and created through the special environment variables CK_INPUT_PATHS and CK_OUTPUT_PATHS.

Stuff you probably don't care about
• The Inspector Panel is now scrollable. Lots of new options coming soon, so these had to go scrollable to fit everything I'm working on.
• The Output Path section of the Inspector Panel has been tweaked for clarity.

Fixes
• Kit files in a subfolder of a CodeKit Framework were not found for import linking. That sucked. Let's not do that anymore.
• TypeScript error messages stopped being displayed in the log. You make ONE joke about Bill Gates on Twitter, and suddenly all the Microsoft stuff stops working in your app.
• If your DOM is really complex, Browser Sync could fire events on the wrong element. This is no longer the case.
• Clicking 'Apply' while editing the AutoPrefixer Browser String in Project Settings will no longer discard your edits.
• The 'Pause File-Watching' menu items now update their titles correctly when file-watching is, in fact, paused.
