Experiences with ver 15.4.2.126 - Are there any Early adopters feed back?

So far at least one of our customer reported that users can't login reliable anymore since the update. (SFTP, Web UI)

Sometimes it shows a "Login was not successfull" Error, sometimes it just hangs with the hourglass spinning and seldom it works.

ok, even "anonymous" logins were no longer possible.... (tried ftp, sftp, http)

when I set a new password for the user(s), it seems to work again

are we really back to the time when users with  passwords that still use the old MD5 encryption are no longer allowed to log in?
