Patch 4 for Assassin's Creed Unity is on hold 

Ubisoft has elected not release Assassin's Creed Unity's patch 4 this week as originally planned and has put it on hold until more testing has been done.

The publisher promised last week that the highly-anticipated fourth patch for Unity was to be released this week. This is no longer the case, according to a new update.

"Rigorous quality control is of paramount importance to us, and your feedback over these past weeks has indicated that it is important to you as well," reads the statement.

"As stated last week, we’d expected to release the patch today (and we know that many are anticipating its release), but we are choosing to hold off until we can give you the improvements we've promised. We are committed to delivering major performance improvements, which requires that we refurbish the Paris map and that will take a few more days to hit the high level of quality our players deserve."

The patch is supposed to be the one that fixes most remaining issues, but more importantly, stabilises the game's framerate.

It is not clear at this time whether or not the patch will make it out before the holidays.
