This one is another heap of polish as we near the 7.0/VotM official release.
Zenith Hydras, one of the new VotM ships, were significantly reworked. Before they were a solid combat ship, but ultimately not very interesting. Now they spawn extra heads (as separate ships) after taking a certain amount of damage. The heads are short-lived but add a substantial amount of DPS compared to just the main unit.
The Objectives tab of the Stats window received several hours of work to improve its existing listings and add a ton more.
And there's a bunch of balance and bugfix stuff, too.
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.
