The outstanding Flash Platform doc blog has a link to the new admin guide for Player 10.1. This document covers tons of information including:
- Player environment (file storage, processes, and versioning)
- Installation
- Administration settings (primarily privacy, security and disk space settings)
- User-configured settings
- Security
Much of this stuff is critical to Flex as well as Flash developers.

The doco doesn’t mention how to disable hardware acceleration via mms.cfg.Sure, I could get all our users to right-click flash content and untick Enable Hardware Acceleration, but I want to be able to do it in mms.cfg.
