New features in the 2.10 series

Since 2.10.4 is strictly a bug-fix release, here’s an overview of the most prominent new features and improvements as introduced in 2.10.0:

Experimental features

The API is subject to (possibly major) changes in the 2.11.x series, but don’t let that stop you from experimenting with them! A lot of developers have already come up with very cool applications for them. Some examples can be seen at http://scalamacros.org/news/2012/11/05/status-update.html.

A big thank you to all the contributors!
