I just downloaded from here: https://svn.openttd.org/tags/1.5.3/ which was obviously a mistake

I just compiled from source with diff on Mac but it had an M at the version information 1.5.3M so citymania server responses with version mismatch! Any chance to add M versions to server version checking?

Edit: don't worry just recompiled from citymania provided src package
