Warcraft III: Frozen Throne Patch is a free software update released by Blizzard Entertainment, for the Windows and Mac versions of their game, Warcraft III: The Frozen Throne.
This patch only works for WarCraft III with the Frozen Throne expansion pack installed. If your current version is patched to version 1.25b, you will only have to install the upgrade patch version to 1.26a. You can verify the version number of the game at the bottom right hand corner of the main menu when you start up the game. If you've recently installed or reinstalled the game, or your version of the game is far behind the current version, you will need to download and install the full Universal patch.
Changes in 1.26 include:
• Hex will no longer provide a speed boost to a Hero if cast at the end of Metamorphosis or Chemical Rage effects.
• Reverted the 1.25b fix, "Hex will no longer extend the duration of Metamorphosis."
• Fixed an issue where some Mac patches could lead to disconnections during Battle.net games.
Aside from these changes, the latest patch will allow you to play online with other players who are also running the latest version of the game.
