PhoenixMiner 5.2b 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 released two days ago, so if you are already running it, there is no need to upgrade. Also, if you do not intend to mine Ethereum Classic (ETC) you can stay on PhoenixMiner 5.2e for now because there are no other significant changes besides the support for ETCHash.
