Raphael van Lierop from Relic posted this on our forums:
Just an update. This patch will address a wide variety of issues covering pretty much every area of the game — SP missions, gameplay, some art, performance issues, balance tweaks, along with some of the other things Tranj has already mentioned.
As I’m sure you can appreciate, patching a game like CoH is a hugely complex process which involves extensive testing of the entire game, and every version (so, all locales — US, UK, Germany, France, etc. etc.).
Hopefully this gives you some idea of why it takes a bit of time to put this stuff together and to validate our fix list.
Once we know EXACTLY what has been fixed, we’ll post the list for you guys to rant/rave about.
Thanks for your patience!
In addition, once QA has validated the patch we can expect a full changelog. This may take the aforementioned one or two weeks though.
For those of you wondering why this is taking so long, QA is the final stage of patch testing. They attempt to find bugs with the patch, and if they find any the whole thing gets sent back to the developers, who then fix it and re-submit it to QA. This may seem like a long-winded process, but it is necessary in order to keep the patches as bug-free as possible.
