Observations and broken stuff so far:
- LLSideTray is gone.
- LLBottomTray is gone.
- LLFloaterSnapshot was changed and gave lots of merge conflicts. Flickr upload will be broken.
- LLNearbyChat is derived from LLPanel now. That broke quite some stuff rearding autohiding and docking of chatbar.
- Profile floaters are gone and all web based now.
- Russian translation gave huge mere conflicts with the new russian xml files from LL. Unmergeable. I took the LL files.
- XUI files in general will need some love and testing.
