v0.8.1

Bug Fixes

• fixed double seeding when using tegola cache seed tile-list with the --map flag (#553 @ARolek)

v0.8.0

Features

• provider/gpkg: use aliases and quotes in query for all column names (#486 @olt)

Bug Fixes

• provider/gpkg: fixed index query for geomFieldname != geom (#486 @olt)
• provider/postgis: fixed error not thrown if the database user does not have permissions to access table (#538 @ARolek)

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_origin is no longer supported under the webserver config section. The same functionality can be implemented using the [webserver.headers] config which allows for configuring almost any response header. Use Access-Control-Allow-Origin = "yourdomain.com" in the config moving forward.
• Docker container now uses the ENTRYPOINT command. Users of the Docker container will need to update the commands they're passing to the container.
