This one is near the end of our polishing the game to get it ready for 6.0. There's one more chunk of changes I want to get in before calling it a release candidate.
So this one's basically bugfixes and some balance, including many smaller suggestions from our players that I hadn't gotten to until just now. Please hammer away on it and tell us if anything breaks.
One notable change is that champion respawn is no longer completely free; it now requires a small amount of capacitor charge to happen and completely discharges the capacitor. The end result is that "dying" twice in row (or once, after totally draining the capacitor on abilities) will cause about a 20 second delay before respawning again.
It's been a long road since 5.0, and even since the start of the Ancient Shadows beta, but we're almost there.
This is a standard update that you can download through the in-game updater itself, if you already have 4.000 or later. When you launch the game, you'll see the notice of the update having been found if you're connected to the Internet at the time. If you don't have 4.000 or later, you can download that here.
