- Extra newline at the end of all templates. Some deployment setups
  removed the last characters.
- Improved PNG performance with PIL fastpng branch.

  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.
