We are finally ready to announce the release of MapProxy 1.1.0. It contains lots of major and minor improvements.

The latest release is available at:

To upgrade within your virtualenv:

Updated documentation is available at:

MapProxy 1.1.0 is the first version that is released under the Apache Software License 2.0. This replaces the old GNU AGPL License terms with a more open and liberal license.

New features

Some noteworthy improvements since 1.0.0 are:

New sources

There are two new sources that directly integrate Mapserver and Mapnik into MapProxy. There is no need to setup an extra WMS server for these map services.

See MapServer source and Mapnik source documentation.

The tile source was extended by the arcgiscache_path and bbox parameters. arcgiscache_path allows the integration of existing ArcGIS tile caches (L09/R05397fb1/C0012d687) and the bbox parameter is useful for WMS-C services that expect a fixed parameter order.

See tile source documentation.

Tagged WMS Sources

You can tag WMS source names with layer names. It is no longer required to specify a WMS source multiple times, for each layer combination you use. You can now define a WMS once without any layers and then tag the source name with the layers you need.

  type: wms

  sources: ['wms1:lyr1,lyr2']
  grids: [mygrid]
  sources: ['wms1:lyr3,lyr4']
  grids: [mygrid]

See WMS documentation.

Configurable Image Formats

Image formats are now much more flexible. You can now create custom image formats and modify them for each source or cache individually. The configuration of paletted PNGs or the JPEG quality is no longer a global option.

See image options.

There is now also support for integer images, e.g. for DEMs.


There is first support for the OGC WMTS standard. It implements KVP requests and can be used with existing caches.

See [WMTS service documentation] (

Improved logging

The logging was improved and unified. System information is now logged at mapproxy.system, configuration errors at mapproxy.config and all source errors under mapproxy.source.wms, etc.

All requests that MapProxy makes are now logged to mapproxy.source.request. The request log format changed and it now contains the complete URL (easy to copy&paste), the size and the duration of the request. The log contains also requests to non-HTTP sources like Mapnik or Mapserver.

See deployment documentation.

Improved configuration loading

The configuration loading is now more robust. You shouldn't see any stack traces when your configuration contains any syntax errors. The MapProxy and the seed configurations are now validated and you should see detailed information about missing or unknown options.

Cache location

The default location of the cache will change with the next release (1.2). The current default is ../var/cache_dir which is appropriate for the configuration from paster create, but not for the configuration from mapproxy-util create (see below). You should configure globals.cache.base_dir with your cache directory. Until then you will get a FutureWarning during startup.

New mapproxy-util command line tool

There is a new mapproxy-util command that replaces the paster command for running the development server. You can now start a test server with:

mapproxy-util serve-develop mapproxy.yaml

Paster (PasteDeploy/PasteScript) is no longer a requirement, but it is still supported.

See deployment documentation.
