Due to a pastie confusion, an unrevised version of the announcement was posted. Since editing posts is not supported (?), here is the intended announcement:

After a significant amount of re-writing, the Waves framework has reached 0.7.5. Official announcement is here at the Hang Ten blog. New features range from Layers, a way of easily reusing code across applications where we have already begun to move many core functionalities, to a blackboard that acts as shared storage during request processing. 0.7.5 is a doorway release, getting the Layers code and various fixes out there while we work out the even more revolutionary features soon to hit a shore near you. Note: when you gem install waves you will find yourself with 0.7.6. This is because we couldn’t help but give you even more awesome! 0.7.6 features updated gem dependencies as well as improved support for stopping waves-server in Windows and a fix for destructuring params in the controller. Please feel free to join us in #waves on irc.freenode.net with any questions or just to jump in the fun that we are having on edge.
