Updates to Left 4 Dead 2 have been released. The updates will be applied automatically when your Steam client is restarted. The major changes include:

• Added protection against possible memory corruption from oddly sized avatar images
• Added handlers for two crash types that weren't getting picked up by our crash reporting system
• Added dlc directories to whitelist for consistency checking
• Flagged whitelist.cfg, motd.txt and host.txt to not clobber local versions on updates
• Updated some translations
