Just a small clarification:
a) regarding beta status of some versions: it makes no difference if you update from previous version to current release version directly or thru beta version. Final state is the same, just the number of files downloaded is higher in the 'beta way'.
b) Updating to latest release from previous release by invoking updater is faster for you (only differences are downloaded) and better for us (lower bandwidth consumed). I estimate it's about 5x-10x faster by the diff way compared to full download.
