A new post on the TF2 Blog happened today. They highlighted that the patch notes will include a lot of bug fixes. Today they highlighted that Badwater is being looked at to fix a lot of the spots that are accessible by rocket/sticky jumper and sentry jumping. They also highlighted two new maps, cp_process and cp_standin. Process is a standard 5-cp map, probably familiar if you play UGC Highlander. Standin is a free-for-all 3-cp map, and has only been used in one of the UGC Highlander summer seasons to my knowledge.
