Changelist for 1.0.73:
-Fixed a memory leak
-Fixed crash bug w/ healers
-Fixed double-staff bug
-Mod support extensions:
--Unload mod from title
--Data driven level cap
--Audio support
--Voiceover mods now possible

I have sent the latest windows/mac builds to GOG, who should post an update soon-ish when they're finished reviewing it.

UPDATE: I just pushed version 1.0.74 to Steam, but the only thing that is included in that patch is a fix for Steam Cloud saves, which means there's literally nothing new in version 1.0.74 for all other services.

So everyone else will stay at 1.0.73 until the next patch, but will have the same functionality as Steam (other than cloud saves, etc).

So don't fret about the version number!
