Blizzard has released the latest update for its gracefully-aging Warcraft 3. The patch usurps version 1.21c and sets you up for version 1.22a. Included in the patch are balancing tweaks, new maps from contest winners, fixes to exploits, and much more. The patch can be downloaded from Battle.net or Fileshack and works for both the original Warcraft 3 and the Frozen Throne expansion.

Here's the changelog:

Features

• There is now a replay auto-save feature in the options menu. Replays are automatically saved to the "replay" folder.
  
• The game is now automatically saved in the event of a potential disconnect. These saved games are placed in the "save" folder.
  - Player color selection can now be limited by the number of players in the game using an option in the "Advanced Options" screen during game creation.
• Added an option to always show unit and building health bars.
  
• You can now enable and disable the display of minimap signals from players and other observers using chat commands: /showminimapsignals and /hideminimapsignals.
• Added a new in-game cheat "maxfps" to limit the maximum frame rate to the given number. Example: "maxfps 30" will set the maximum frame rate to 30 FPS.
