Important: * You have to re-extract and assemble vmaps * Update your config file, new option 'vmap.enableIndoorCheck' added New features: * Include WMO+DBC area information for correct subarea identification and indoor check * Support for WMO liquid (fishing/swimming in cities, instances and oterh WMO based environments) Technical changes: * New Bounding Interval Hierarchy (BIH) data structure for better performance * Referenced model data for reduced memory usage, needs more files, but reduces overall file size from ~1.9GB to ~550MB Additional Authors: arrai (DBC handling and indoor detection) faramir118 (windows support and bug investigation) And of course thanks Vladimir for a lot of patience and support!
