There is always a "work version", followed by an Alpha 1 release, usually followed by an Alpha 2 release, then followed by closed Beta which is followed by any number of public betas. Discovery usually does its public betas on the main server, as we don't go onto betas until the Alpha is stable enough to run without crashes. Alphas are always closed, only used by the development team and testers. Friday is one of those. These changes are already in the Alpha, and thus, he sees them when he goes bug checking. (Things not in the Alpha yet, or things planned for it but not started, are not released in public logs such as this.)
