This one has two very key bugfixes, and a handful of other tweaks.
The first bugfix is one that was causing desyncs in multiplayer, occasional stupidity on the part of the AI, units moving onto enemy units, and more. It wasn't very easily reproducible, and wasn't super common in every game, but it all tracked back to an error in how the playback of melee units worked... in certain circumstances (mainly if they were standing on the tile they were attacking).
It also didn't manifest if you just ended playback rather than actually watching them play out their attack. So, yeah -- that was hugely difficult to track down until a player came up with a perfect savegame that let me reproduce it reliably. Then it was easily fixed within 15 minutes, but prior to that it was a frustrating needle-in-a-haystack situation that only happened sporadically, and that it wasn't clear was actually all one issue.
The second fix is to the military commandments not working properly in terms of getting regular units to go attack gods. This was accidentally messed up right before we released the game, and now it's restored to how it's supposed to work.
Beyond that and the few other tweaks, today has largely been a "measure twice, cut once" sort of day with us doing a lot of talking with players about proposed changes rather than actually implementing a flurry of changes. This process will hopefully lead to something more refined on the first try of implementing said new features, rather than a disorienting flip-flopping around of how the game works for players not involved in the discussion.
Anyway, those discussions are starting to bear some interesting fruit, but we're not there yet on them. In the meantime we're working on a few new features, and also are going through the list of mantis issues logged. By the by, if you're inclined to submit ideas for new Woes, feel free to submit those on our forum thread for new woes or in the issue tracker.
This is a standard update that you can download through the in-game updater itself, if you already have any version of the game. When you launch the game, you'll see the notice of the update having been found if you're connected to the Internet at the time.
