Server Admin Notes:

Expect an increased server load with 8-10 players on fully detailed Capture The Flag maps. RAM can jump from 30MB to 110MB and it's possible to be sending 30kb/sec per client.
This will be optimised in the future but for now, keep an eye on your server loads.
We are currently investigating a crash bug with the dedicated server software -- please send any crash reports.

Known Bugs:

Cloth occasionally vanishes -- just treat it as "Capture The Pole" until it comes back.
This is a huge release so expect this list to grow. Please send all crash reports!
Getting a few crash reports in the new occlusion engine. You can use r_occlusion 0 to disable it as a workaround for now. (update: this is occurring on older CPUs, working on a fix currently)

Game:

Non-team games will now use teamA for player colours (or enemy if relative override set)
Updated dp5 by Def

Bug fixes:

Added scalar fallback for occlusion engine, required for CPUs that don't support SSE4.1
Players should no-longer be saved into light light shadow maps

Improvements:

Flagged crashreport to auto restart the app on crash on dedicated servers
