We have stopped providing daily snapshots for phpMyAdmin pretty much at time we've moved to GitHub, which allowed to download any branch as zip file. However since introduction of Composer to manage our dependencies, additional steps were required to get working copy of phpMyAdmin out of the snapshots.
Since today the ready to use snapshots are available again. They will be updated every day and are built in exactly same way as our releases, so all you need to do is download them and start using.
These snapshots can be also used from Docker - the phpMyAdmin image now has brand new tags
edge-4.8 which are updated with every snapshot and contain latest changes from development branches.
