- fixed the way cache seed / purge with a tile-list or tile-name works. min and max zooms now must be provided for tegola to include parent and child tiles (@gdey)
Breaking Changes
- IMPORTANT: if you have a current tile cache in place, you will need to purge it entirely as tegola now expects the cache to persist gzipped tiles.
cors_allowed_originis no longer supported under thewebserverconfig section. The same functionality can be implemented using the[webserver.headers]config which allows for configuring almost any response header. UseAccess-Control-Allow-Origin = "yourdomain.com"in the config moving forward.- Docker container now uses the
ENTRYPOINTcommand. Users of the Docker container will need to update the commands they're passing to the container.
