Sage 7.0.rc0 released

[Volker Braun]

As always, you can get the latest beta version from the "develop" git branch. Alternatively, the self-contained source tarball is at http://www.sagemath.org/download-latest.html

As mentioned before, there are no incremental updates from 6.x. You need to compile from scratch, e.g. after cleaning with "make distclean" or "git clean -f -d -x". If you are still working on tickets based on 6.x then you might want to use a separate git tree for sage 7.
