- new OpenLayers-based '/demo' service that shows all configured WMS/TMS layers
- display welcome message at '/' instead of 'not found' error
- less rigid feature info request parser (no error with missing style or format
  parameters). Use wms.strict to enable OCG compliant mode.

  removed the last characters.
- Improved PNG performance with PIL fastpng branch.
- New concurrent_requests option to limit requests for each source WMS server.

0.8.3 2010-06-01

- Some bug fixes regarding feature info
- The configured resolutions are sorted

0.8.3rc2 2010-05-25

- HTTPS support with certificate verification and HTTP Basic-
- New `use_direct_from_level` and `use_direct_from_res` options to
  disable caching for high resolutions.
- New `cache_tiles` source for more flexible tile-based sources

  and Quadkeys as used by Bing-Maps. (as suggested by Pascal)
- You can limit the SRS of a source WMS with the `supported_srs`
  option. MapProxy will reproject between cached/requested SRS and
  the supported. This also works with direct layers, i.e. you can
  reproject WMS on-the-fly.
