Today's update brings two changes:
First - the Java SSL code signing cert has been updated. It was about to expire this week, but I got it renewed just in time. So, you might see a popup that the cert has changed.
Second - one suggestion from princewilliam3 in the suggestion box that had accrued a number of votes was for left-handled doors. It seemed like a pretty smart idea, so I implemented it for the latest build. Having one of each looks better for double doors. Here's an example, which is animated for no good reason 😛
Also, since there's now six doors total, they've been moved to their own subfolder in the construction category.
