We'd like to thank all our testers and contributors for bringing us this far. A lot has happened since our 2.2.0 release nearly a year ago. We passed revision 10000 two months ago, and it's getting lots harder to remember these five-digit revision numbers.
We also have a new website design, and an Add-ons database for all our user-contributed maps and mods. It's time to begin work on 3.0. 
But I'm sure you guys are more interested in what's improved in the game itself.
Well, we have a few new keyboard shortcuts involving the Alt key. We darken areas of the map you can't see, too. It is now possible to put multiple weapon turrets on a single tank. Read on for more.New: More keyboard shortcuts!
With a cyborg transport selected, hold down Alt and click on the ground to automatically unload all your cyborgs.
With tanks or cyborgs selected, you can hold down Alt and click on the ground to attack-move there (which will tell them to stop and destroy everything on the way to their destination).
With a VTOL selected, you can hold down Alt and click on the ground to tell them to patrol between their current location and the clicked location.
With any attack unit selected, you can hold down Alt and click on one of your own units to attack yourself. This is not recommended, though, as it's nearly always better to simply right-click on the unit and click "Recycle".
New: Help allies build
New: Sensor visualization
New: Multiple turrets
Improved: Game setup screen
We've also renamed Mayhem mode to Scavengers, so it should be clear that all the option does is enable scavengers on maps that support them.
Improved: Changes to game balance
Cannons have been underused, so we've decided to make the Assault Cannon and Hyper Velocity Cannon easier to research. The Plasma Cannon is now considered a cannon as well, and has significantly higher range than before.
Excluding artillery, the Heavy Laser now has the highest range in the game. Its damage has been slightly lowered to compensate, but with enough of these, your base should be well protected against attacks by hovercraft and cyborgs. The Seraph Missile's range has also been increased.
Cyborgs move slightly faster now. Cannons and mortars have a larger splash radius. Hovercraft are now more vulnerable to artillery fire, but tracked tanks are less vulnerable.
New: Bundled DyDo AI mod
Warzone now comes with the DyDo AI, an improved version of the BecomePrey AI. This AI is significantly harder than the default AI. The default AI has also been improved.
New: Challenges game mode
We now have a new game mode in the Single Player menu called Challenges. See who can complete a fixed game setup the quickest!
Improved: Game lobby
The game lobby now shows the version and mods of all hosted games. It also handles passwords much more intuitively than before.
Improved: Cheat mode
Cheat mode is now significantly easier to activate than before. You still won't be able to do it in multiplayer, though.
New: Autoload folder
It's now easier than ever to install a mod - simply drag it to mods/autoload/ in your Warzone 2100 configuration folder (which should be in My Documents for Windows users and ~/Library/Application Support for Mac OS X users). Note: You may need to create the autoload folder if it does not already exist.
Improved: Stability
As always, we've done much to decrease the number of bugs and crashes you experience.
