There will be an update for the game next week. Hopefully it will include more memory optimizations for 32 bit systems.

Crashdumps should get uploaded by the crash report program, or included in a report generated by the D:OS support tool.

There are buttons at the top of the chat window to switch between local and global chat. The sliders for quick/autosaves are for the number of saves kept.

Updates have not ceased, and Larian has occasionally posted here, the Steam discussions, D:OS chat, twitter, etc. They have been relatively consistent releasing updates every 2 or 3 weeks, and forum activity always increases with a new update and then tappers off.
