Milestone 8.0 beta 2

Second public beta release.

We intend this release to be a bug fix and a feature finish release, which will act as the Release Candidate for the official release of version 8.0.

By this time we will be migrating our support site to version 8 as well, to see if all functionality is where we want it, and to finetime the installation and migration scripts. This is also the time to update and finalize the documentation, especially with respect to installation and upgrade procedures.
