New beta is out - mostly a collection of fixes and requested tweaks.
If you add the setting ‘minimapMaxWidth’ to application.sublime-options, then you can change the value from the current default of 175 (Note there was no pixel maximum width in previous versions, the algorithm for calculating the width has been changed).
Nick’s plugin for line indentation detection is in there too, configurable via the file type option ‘detectIndentation’. It’s on by default. There’s a new View/Indentation sub-menu to go with it.
There are a couple of new methods in the API: sublime.messageBox and sublime.questionBox.
Finally, there’s now a system for packages to integrate into the menu: Create a *.package-menu file (Same syntax as the *.sublime-menu files) in the package directory, and it’ll appear as a sub-menu under Tools/Packages. It’ll likely move into a top level menu at some point, when it actually has some content.
