The patch was supposidly meant to be put on the test servers today but ""At the last minute we found a problem with the patch which could break the installs of a small percentage of users."

Let us hope this is not a sick joke by Blizzard as the Warcraft3 community has waited long enough.

Here are the Patch Notes for 1.22:

Features

* There is now a replay auto-save feature in the options menu. Replays
are automatically saved to the "replay" folder.
* 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.

Balance Changes

Human

* Scout Tower repair rate changed from 12 to 20.
* Knight damage increased: Attack cooldown changed from 1.50 to
1.40 and base damage increased from 25 to 28 (Average damage is 34).

Undead

* Increased Ziggurat base armor from 1 to 5.
* Reduced the build time of the Necropolis from 120 to 100.

Night Elf

* Reduce the Orb of venom poison duration from 10 seconds to 8 seconds.
* Increase the experience gain from Dryads from Level 2 (40xp) to
Level 3 (60 xp).

Fixes

* The cooldown on unlimited usable items (example: the staff of
preservation) now persists after the item is dropped or traded.
* A cooldown exploit with potions has been fixed.
* When you unburrow a Crypt Fiend, its auto-cast will no longer be toggled
off.
* An exploit bug in which items could lose their cooldowns when transferred
between heroes has been fixed.
