I could not find any Sublime Text syntax highlighting package for AutoHotkey version 2, so I ended up making my own. Perhaps someone here will also find it useful.
It includes auto-completion for all the new v2 functions and proper syntax highlighting for strings (with the change from "" to `"). It's not perfect - there are some details that have not yet been ironed out, but I have been (slowly) updating it as I notice inconsistencies. Feel free to report issues if you decide to use it and think it can be improved.
