There are a few new features, as well as a collection of fixes.
There’s a new option, copyOnMouseSelect, which will automatically copy the selected text to the clipboard when selecting with the mouse - this is experimental, and may be removed in the future.
Also, due to popular demand, the wantScollBars option has been split into two options for horizontal and vertical scrollbars.
I’ve made some changes to PackageSetup for this release, and while I’ve tested it and everything appears fine, you may want to backup your User/Default.sublime-keymap file in case it does get eaten.
