Some things you need to know about the patch 1.24b:
1. Custom Maps that can be played on this patch is still very small, popular folders like Fight of Characters, Battle Arena, Tower Defense, Tree Tag, etc, until now could not be played. Only DotA version 6.62 and above who have really adjusted to be compatible with the 1.24b patch.Another map that can be played only the old folders that scriptnya still very simple.
2. From 1:23 to patch up, there was a big change in the organization of the binders in Warcraft 3, it is among others aimed to improve the gap in the case folder collided. One effect is Warcraft 3 can not recognize the folders that have the file name is too long. So if you feel you've put the folder in the correct folder, but still can not find the time to Create Room, try to rename a file from that folder becomes shorter.
Example: "DotA-Allstars v6.61c.w3x" change to "v6.61c.w3x" only.
How to Upgrade:
1. Download "NSRPatch Pack v1.24b-ins.exe" (53MB)
2. IMPORTANT! Put it in the folder Warcraft III
3. Double-click and do the install.
4. Run Warcraft 3 and make sure the version is 1.24.1.xxxx, which means patching process has been successfully
Warcraft III 1.23 Patch now is in Beta stage released and available on Westfall and other server. Ok, so what? What's the benefits of this patch for us Dota Player? Well, after i read the changelogs, i cannot helped to say that this Warcraft 1.23 patch is created solely to support Dota-Allstars. I think Blizzard is really love Dota-Allstars. Curious? But before i go through, it'd better if you read the official statement from Battle.net first:
You may notice that the Westfall realm is available on your Warcraft III Battle.net list. The Westfall server has the beta Warcraft III 1.23 patch that can be applied by connecting to Westfall. Please keep in mind that Technical Support does not support the beta client. For patch and game discussion, please use the Warcraft 3 forum - http://forums.battle.net/board.html?forumId=12012&sid=3000
To revert your game back to 1.22, just select one of the main realms.
If you cannot connect to Westfall, it's probably down or not ready.

Patch 1.23
--------------------------------------------------------------------------
FEATURES
- Battle.net now uses a new banner ad system.
FIXES
- Fixed an exploit where an altered custom map would be seen identical to the original custom map.
- Fixed an issue where some patches could not apply on Intel Macs.
Ok, now read this part once more, Fixed an exploit where an altered custom map would be seen identical to the original custom map. This means, if there's someone play using hacked map (where the fog is turned off), it will be seen and cannot play with the original map. Neat! But sadly, this will also means we cannot use multiple language map in one game. We must use exactly the same map. But i prefer no maphack than multiple language map ^_^
(Edit: Someone says that the multiple language still work, must confirm this again)
