Hope you are all having a wonderful festive season.
Update information and full blog post here.
Please note:
We have tested this build to the best of our ability, if you have any problems with this new version please post a bug report on the Steam forums.
I will try my best to sort them out as soon as possible, I will also provide a build of the old version if you wish to continue using that below.
If you want to access the old stable or future experimental builds
Right click the game in your Steam library and choose properties,
under the Betas tab select Experimental or Old Stable from the drop-down list, make sure you are not running the game when you do this.
