This release is a preivew of some of the features that have been developed for M2. It is not complete, so there are still some use cases that haven't been streamlined. The first run experience after installing the bot has been improved remarkably, and I'm recommending that all users do a clean install to pick up the new H2 database engine, which is much faster than Derby in most cases. Derby will still be supported until the release of M2, but after that you'll be on your own unless you switch.
