This is the final release of EMAN2.0x before the prerelease version of EMAN2.1. EMAN2.1 will have some important changes which will effect backwards compatibility (BDB is being retired from EMAN2 in favor of HDF files and text files). This release version has a wide range of gradual improvements made over the last 10 months. As soon as the first 2.1alpha testing release is out, the nightly snapshots will be 2.1 snapshots rather than 2.0 snapshots, so this release version will be the canonical version of EMAN2.0x.
Naturally users of the snapshot versions have already seen most of the changes in 2.07. This version is really just a stable snapshot release.
