From Fuzzy's post on Github:
Bugs Squashed
-Gen 6 mechanics were adjusted on many moves and ability. Well over 100 bugs met their end here.
-Gen 1 might be old, but Withoutatrace didn't forget it! A number of bugs that affected mechanics have been eradicated.
-Challenge Cup level balancing was adjusted to change between generations, instead of always assuming latest gen. This will affect Gen 1 the most as the formula was different in accounting for the Special Stat.
-Speaking of Challenge Cup, Arceus, Giratina, and Genesect will now properly display according to their items.

Clients Updated
-Gen 6 Sprites are now in use. They are simply a frame-grab from the animated model. As a result of...

Currently, the Android version has been removed from the Google Play Store. However, you are still able to download it and use it, though the process is a bit different.

Step 1: Under “Settings,” select “Application Settings” and then enable “Unknown Sources.” [Note: You can re-disable "Unknown Sources" after the installation is complete if you would like]
Step 2: Tap the green button below and install.

If you're reading this, you likely just saw the site change completely and are wondering what in the world is going on! Well, to put it simply, the site has been redesigned and moved to Xenforo. In this post I'll explain a lot of things and hopefully answer some questions you might have regarding what Xenforo is and why the move occurred.

So first things first, Xenforo is a forum software created by 2 people, Mike and Kier who were some of the main developers for the vBulletin software. However when the company Internet Brands bought the company Jelsoft (The original owners of vBulletin), they put things into practice the workers didn't like. So, they moved on and created this (arguably) better forum software. It's got lots of awesome features that aren't available in vBulletin, some of which I'll be going over here.

Resources
As for the first feature I'll go over the Resources section, since it's what I'm personally most excited about as a designer. It's completely fresh, so...

The new version (2.4.0) of Pokémon Online for Android was just released!

This is mainly database update (moves, pokemon, movesets, etc) along with a few bug fixes. Enjoy!

Google Play

Plenty of bug fixes, new moves, new pokemon cries, etc!

Window flashing problem should be fixed, and new battle window should work for everyone now! (try it, in battle options :) )

The plugin system was also greatly improved, it's just a matter of checking which plugin you want! For example, you can just check the "Script Window" plugin, then click the button "Get Moogle's scripts", and you'll have access to plenty of additional features such as the friends list.

Server owners should read this.

A new version just came out!

After the official release of gen 6, it was time for patching all the bugs people reported and that had escaped us. It was also time to add new eggmoves and update some sprites :)

Serverside, some nasty bugs like the Disconnect + Tie glitch and the AntiDOS bans were fixed too!

On android, we also fixed a bug in the teambuilder, and better support for GSC/RBY in the teambuilder!

Downloads (Windows, Linux and Android for now)

You can now fight in the gen you want with the android app!

Formes support was also improved, with a better way of selecting formes! (And no more selecting megas directly from the teambuilder :p)

It's version 2.3.1. If it's not on the play store yet, you can get it here :)

It fixes all the previous generation-related problems, as well as a few crashes, too!

Gen 6 was officially released, less than a month after the game!

You can check out the downloads there. (v 2.3.2)
v 2.2.9 is the latest version for Mac at the moment, please be patient for a more up-to-date version.

Gen 6 is on android! Version 2.3.0.

You can check on google play, or if it's not yet updated, on github.

So now you'll be able to battle other players on X/Y :)

Note: If you have a team from the past, and you want to use new X/Y pokemons, use Menu > Reset team.

There is now a Mac download for v 2.2.9 too!

You can find it from the Downloads page! It is expected to work on Lion, Mountain Lion and Mavericks.

Sorry Snow Leopard users, currently I am not able to provide a build for you.
