0.10.2 (2019-08-30)

Features

  • added tegola_lambda_cgo to the build pipeline. Geopackage can now be used with tegola_lambda (@ARolek)

0.10.1 (2019-09-03)

Bug Fixes

  • server: fixed cache middleware removing incorrect path prefix when a uri_prefix was set. (@ARolek)
  • server: fixed internal viewer URIs when a uri_prefix was set. (@ARolek)
  • server: fixed internal viewer file paths when a uri_prefix was set. (@ARolek #361)

0.10.0 (2019-08-30)

Features

  • cache/redis: add configurable key expiration time. #600 (@tierpod)
  • server: configurable webserver URI Prefix #136 (@ARolek)

Bug Fixes

  • server: Content-Length for non-gzipped responses (@thomersch)
  • cmd: tegola command fails when running version subcommand without a config. #626 (@ear7h)

Maintenance

  • Upgraded internal viewer Mapbox GL JS to 1.0.0 (@ARolek)
  • Skip S3 tests on external pull requests (@gdey)

Breaking Changes

  • If a webserver.hostname is set in the config the port is no longer added to the hostname. When setting the hostname it's now assumed the user wants full control of hostname:port combo.

0.9.0 (2019-04-09)

Features

  • Add support for per map tile buffers (#501 @tierpod)

  • provider/postgis: no error thrown when geoFieldname is missing (#590 @ARolek)
  • server: User defined http response headers are not added to OPTIONS requests (#594 @ARolek)
  • atlas: Handle empty geometry collections (#429 @paumas, @ARolek)

Maintenance

  • Update sqlite driver. Driver understands strings now. (@gdey)
  • Updated CI to use Xenil (@gdey)

0.8.1 (2018-11-07)

Bug Fixes

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

0.8.0 (2018-11-01)

Features

  • provider/gpkg: use aliases and quotes in query for all column names (#486 @olt)
  • provider/gpkg: improve column name extraction (#486 @olt)
  • provider/postgis: added support for !pixel_width!, !pixel_height! and !scale_denominator! SQL tokens (#477 @olt)
  • provider/postgis: Support for sub-queries as "tablename" (#467 @olt)
  • provider/postgis: Set default_transaction_read_only when connecting to PostgreSQL (#369)
  • cache/s3: added default mime-type of application/vnd.mapbox-vector-tile and made it configurable (#459 @stvno)
  • mvt: don't require IDs for mvt features. (#337, #338 @ARolek)
  • server: gzip encoding of tiles (#438 @ARolek)
  • server: set proper MIME type for vector tiles (#511 @ARolek)
  • server: configurable response headers (#519 @tierpod, @ARolek)

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)
  • cache seeding: invalid value for bounds () with 10e3 notation (#539 @gdey)
  • 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_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.
