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.
