A quick bugfix release to 3.0.0 - if you haven't upgraded before, now's the time!
Search area is now visible by default again, similar to how it was in 2.1. The redundant 'Search' button was removed to save space on smaller screens and a new collapse/expand button is in place.
You can now choose to save your maps in versions 17 and 18 in Preferences > Special Options. Technically speaking, you could choose to save your maps in 3.0.0 in newer formats as well, but it then wouldn't be able to load them - now it can.
Map format 17 allows you to use map and area user data functions - similar to room userdata that was available already. See searchAreaUserData(), setAreaUserData(), clearAreaUserData(), clearAreaUserDataItem(), getAreaUserData(), getAllAreaUserData(), setMapUserData(), clearMapUserData(), clearMapUserDataItem(), getMapUserData(), getAllMapUserData().
Map format 18 will save your players location when copying maps to other profiles.
