I've read on RPGCodex that Gaze of Adragan has been nerfed too but it has not been mentioned in patch notes. If anyone finds any other undocumented changes please post them here too.

Another one, floating combat text for healing has been added.

The autopause bugs in which "weapon ineffective" was triggered by the enemy's weapon being ineffective (instead of yours) and "spell cast" was triggered by your characters casting a spell (instead of the enemy casting a spell), have been fixed.

Patch 1.05 features hundreds of bug fixes, balance changes, and new UI features. There are many minor fixes that are not listed in these notes.

So yeah, there's probably a lot more that hasn't been mentioned in the patch notes...

Is just a beta patch notes to begin with ...

Yep, most patch notes do not include every last thing. Usually just the highlights. Or, some dev would be stuck writing a small novella every time a patch was released.

Gaze of the Adragan has about half the duration that it did previously.
