R2.1 entered internal (alpha, I suppose) testing last week and has since rolled through 3 iterations as bugs were found and feature improvements were raised. It'll soon enter beta testing (so, if you're interested, now's the time to get in touch) and after that I hope to release a Public Beta before we go final.
The list of improvements is long and winding, but here's what pops into my head:
- New API (existing API is still FULLY supported) which should make it easier for high-level languages/systems to access Snarl
- New, better looking, Preferences Panel
- 'EZ Styles' engine which allows for reasonably fancy styles using simple text files
- Network support - specifically, being able to forward notifications, receive incoming notifications and listen for local JSONs
- Support for right-click menus in notifications
- Lots of minor tweaks and improvements
- Better handling and management of 'Snarl Apps' (standalone applications which only talk to Snarl)
