I assume there will be a list of fixes in the patch notes. It would be good to get that part ahead of time in order to balance expectations. As an example while Emporer of Corpses has had a lot of fixes in previous patches, an evade just slid me all way to the right of the map in to the blood puddles, well past where I had targeted when I hit the space bar. Things like this are very annoying.
There will be.
They’ve always given us the patch notes a few days before. Why do you think that 1.2 will be any different?
Few days is subjective. Something a bit more than a few days or a new known issues thread would be nice 
… you know like they used to have in the past 
I don’t remember one of those for LE.
I haven’t been around for long before launch (I joined during 0.9.2) but I haven’t seen one of those either.
In fact, I haven’t seen one of those for any of the major ARPGs.
In fact, I haven’t seen one of those for 99.99% of games released.
Sometimes players make a collection, but I rarely, if ever, see this from an official source.
Probably because the bug list for any given game is hundreds, if not thousands, of issues, it would look bad (even though it happens in all games) and people would complain more as the oldest ones don’t get fixed fast (even though it happens in all games).
