Mostly I've been working on the paragonchat_1_0 branch, which has 92 commits since it was branched and about 21,000 lines of code added or touched in some way.
Before you get all excited, almost all of that is stuff that while I might think it's really cool, most people probably won't care about. It's not terribly exciting from an end-user perspective, except that it lays the groundwork for adding more exciting features later.
Some highlights include:
Tighter integration with the COH client. At first this is just to fix some issues like the 127.0.0.2 problem on WinXP and macs, but it's done in a way that opens the door for more interesting things.
Multithreaded data loading for faster startup.
Improving the new user experience -- making it easier to install Paragon Chat and locate your COH files for it to use.
Complete separation from the Issue 24 beta install directory. Paragon Chat reads the files from there, but now lives completely in its own location and never needs to write anything to the COH folder. This helps avoid UAC issues for people who still have it under Program Files.
User interface improvements and polish.
Better debug logging and lots of other features to aid in development.
Fixing and cleaning up a lot of stuff that was rushed in order to get Paragon Chat usable enough to be beta-worthy, and doing it the right way.
Fixing most of the issues with long path names and non-ASCII characters in directory names.
