@merlos merlos released this 24 Nov 12:06

In this release there are a few things that are fixed

  • In iOS13 MapViews can go to zoom levels of 24 or 25, however most tile servers support till 20. So a new config setting was added to allow you to set the max zoom and min zoom tile levels would be requested (#10)

  • A Round robin algorithm (https://en.wikipedia.org/wiki/Round-robin) was implemented to request the tiles across the possible tile servers. Requests will be distributed more uniformly among available tile servers.

  • Cache size now is measured in two kinds of sizes: fileSize which is the sum of the sizes you get when you run a ls -la and diskSize which is the size you get when you run the du -h command.
