The MD5 hash in the readme.txt (dated 2018-06-16) doesn't match the MD5 hash of the new ISO that was uploaded on 2018-07-19.
readme.txt MD5 hash: b3ad4ddb9cbe91d34949b67473b8affa
downloaded ISO MD5 hash: FF27E253C86ABDCD51C533D4841D3DED
I am assuming that the readme.txt wasn't updated when the new ISO was uploaded. If an OMV team member could verify the MD5 hash and post it, I would appreciate it.
