Dwelvers Alpha v0.7d has now been released to the pre-orderers, you can download it at the Dwelvers website.
(This version is still not considered stable, and I will not do a bigger public announcement until it is.)
To download it you need to go to Dwelvers website, then login with your username and password.
Once this is done a new tab leading to the members page should have become available. Here you can download the latest version.
Upgrades since v0.7c
Feedback is the key - Better building efficiency feedback, better storage room capacity feedback, room chain flags and I got rid of that big annoying item window.
