Status text now displays info about current selection.
Removed StairSectorBuilder plugin. The version form doombuilder.com works fine with current version of GZDB.
UDMF: changing brightness of a wall or ceiling in GZDoom Visual mode will change brightness of selected surface, not sector brightness.
Sector and Sidedef info panels show additional info if a map is in UDMF format.
Fixed: GZDoom menu panel wasn't updated when a map was opened via "recent files" item click.
