This one is relatively small update with a couple of bugfixes. The main thing here is some fixes to flickering in the far zoom icon display that people were noticing in recent versions, as well as what is likely a performance improvement for most people on that front, too.
Update: 8.017 is now out and includes a couple more flicker-related fixes. And yet another performance improvement related to that (a happy byproduct).
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.
