Update 0.6.4.4

2015 Jan 27

## Alpha: Trading, bugfixes, optimizations

Hey folks! Another update is available, it does not introduce much new content, but instead it fixes a bunch of nasty bugs and annoying crashes that kept us busy the last weeks. Due to extensive changes on the technical side of the game, we had to do multiple tests before we were able to release this update (especially in multiplayer) to make sure it does not break anything.

This update also introduces a lot of important optimizations and improvements in terms of memory management, performance and world generation speed, especially in multiplayer, but also in singleplayer.

Apart from that, this update also fixes a crash (when geometry instancing was enabled in combination with amd graphics cards) that has been around for a while now. So if you disabled the "graphics\_instancing" flag in the config file in the past (as a workaround), you should be able to re-enable this feature again (resulting in less memory consumption).

Though this update is mainly about bugfixes and optimizations, at least one new feature is now available: The ability to trade with other players. You can invite a player for trading, and if the accepts, you can exchange items with him. Eventually some sort of currency will be added in the medium term, too.

Of course we are still working on some other stuff in the background, among others water and new playermodels, animations and items. We can probably provide some previews soon ;)
