I will look their new Github repo and compare the checksums.
Awesome Miner uses the official PhoenixMiner 5.5c ZIP-file as a base. Then we add their two "nvrtc" libraries to the ZIP-file to ensure our users doesn't have to ensure all dependencies manually. For this reason, all files like PhoenixMiner.exe are identical to the official PhoenixMiner release. The ZIP-file is however a bit larger as it also includes two more dependency libraries (resulting in a different checksum for the entire ZIP-file).
Update: I've verified the files on the new PhoenixMiner Github page:
https://github.com/PhoenixMinerDevTeam/PhoenixMiner/releases/All matches their official release 5.5c they made in January, also included in Awesome Miner.
Another question, can you include other Pools like for exampe Ethermine to managed profit switching as HiveOn?
