Improved reprojection

The accuracy for reprojections on low map scales improved while the performance improved for mid to high map scales.

Improved HTTPS handling

MapProxy now uses CA certificates provided by your system if you use Python >=2.7.9 or >=3.4. The ssl_no_cert_checks option was broken with these Python versions. This is now fixed. The ssl_ca_certs option is still available for older systems, or for custom CA certificates.

There are a lot more changes and improvements. Please note that Python 2.6 is no longer supported.
