Release notes 202207-1.1
- Multiple identical labels for some solar and wind farms are combined to one for each. Corrected label multiple instances to one. Only 6 maps that contain Europe ZL 11 are affected.

Those are the news from version 202207-1.0:
- OAM base maps updated to May 2022 for Europe and to April 2022 version for the rest of the world.
- After a longer break the ferry connections for ZL 6 and 7 are updated as well as the energy productions (following respective lists from Wikipedia).
- The regional addon and overlay maps are unified: OAM-W1-7-EP8-12-J80.mbtiles (as an example) contains the world up to +/- 85 latitude and ZL 7 as well as a large chunk of Europe from ZL 8 to 12 consecutively. Hence those maps can be used independantly as well as an overlay. Also, now it's only 21 maps and 70 GBs (instead of 110 GB).
- Up to ZL 12 all maps consist of tiles in JPG 80% quality, a real progress compared to the former 60% of the addon maps and somewhat better than the 70% of the earlier world maps. File sizes increase reasonably, wich in over-compensated by the storage capacity increases of recent years. For ZL 13 a quality of 70% is used.
- The maps can be grouped as:
     - world maps ZL 8 to 11; JPG 80%; MBTiles
     - world maps ZL 10 and 11; PNG format; sqlitedb (for apps that cannot handle MBTiles)
     - regional maps up to ZL 11 (all continents), 12 (large parts of Europe) and 13 (smaller segments of Europe); JPG 80% resp. 70%; MBTiles
     The MBTiles world maps are available as direct downloads for Locus and Orux apps; all groups can be downloaded manually, too.
   
Enjoy - and feel free to comment.
