PhoenixMiner 5.7b is officially released. You can find the download link and the checksums in the first post of this thread.

It is the same release as the one that was posted here as beta version, so if you are already running it, there is no need to upgrade.

Note that 5.7b supports the latest AMD Windows drivers 21.8.1 but it doesn't support the latest AMD Linux drivers 21.30. If you have AMD 6x00 card and you want to use Linux, you should use AMD drivers 21.20 but for any older AMD cards, you should stick with AMD drivers 20.30 (the latest stable PAL drivers without bugs).
