~~~~~~~~~~~~~~~~

Features:

Other:

- remove import error warning for shapely
- create metadata table in MBTiles caches

~~~~~~~~~~~~~~~~~~~

Features:

- clipping of tile request to polygon geometries in security API
- WMTS support in security API
- mixed_image mode that automatically chooses between PNG/JPEG
- use caches as source for other caches
- `mapproxy-util grids` tool to analyze grid configurations
- `mapproxy-util wms-capabilities` tool
- `mapproxy-util export` tool
- use_grid_names option to access Tiles/TMS/KML layers by grid
name instead of EPSGXXXX
- origin option for TMS to change default origin of the /tiles service
- continue stopped/interrupted seed processes
- support min_res/max_res for tile sources

Improvements:

- do not show layers with incompatible grids in WMTS/TMS demo
- make 0/0/0.kml optional for the initial KML file
- use BBOX of coverage for capabilities in seed_only layers
- ignore debug layer when loading tile layers
- simplified coverage configuration
- add reloader option to make_wsgi_app()
- add MetadataURL to WMS 1.1.1 capabilities
- improved WMTS services with custom grids (origin)
- use in_image exceptions in WMS demo client
- larger map in demo client
- always request with transparent=true in WMS demo client
- use in_image exceptions in WMS demo client

Fixes:

- fixed reloading of multiapps in threaded servers
- fixed BBOX check for single tile requests
- fixed TMS for caches with watermarks
- fixed limited_to clipping for single layer requests with service-wide
clipping geometries
- fixed WMTS RESTful template

Other:

- deprecated `origin` option for tile sources was removed
- empty tiles are now returned as PNG even if requested as .jpeg

~~~~~~~~~~~~~~~~~

Fixes:

- fix TypeError exception when auth callback returns {authorized:'full'}
- use MAPPROXY_LIB_PATH on platforms other that win32 and darwin
- raise config error for mapnik sources when mapnik could not be imported

~~~~~~~~~~~~~~~~~~~

Features:

- support clipping of requests to polygon geometries in security API
- support for WMS 1.3.0 extended layer capabilities
- on_error handling for tile sources. fallback to empty/transparent
tiles when the source returns HTTP codes like 404 or 204
- add HTTP Cache-Control header to WMS-C responses

Improvements:

- WMS source requests and requests to cached tiles are now clipped
to the extent. this should prevent projection errors when requesting
large bbox (e.g. over 180/90 in EPSG:4326)
- improved lock timeouts in mapproxy-seed
- the debug source does not overwrite the layer extent anymore.
makes it more usable in demo/wms clients
- support for multiple files and recursion in base option
- mapproxy-seed ETA output is now more responsive to changes in seed speed
- improved demo service
- choose different SRS for WMS layers
- support for WMTS

Fixes:

- support loading of WKT polygon files with UTF8 encoding and BOM header
- upgraded dictspec module with fix for some nested configuration specs.
a bug prevented checking of the layers configuration

Other:

- the documentation now contains a tutorial
- old layer configuration syntax is now deprecated
- EPSG:4326/900913/3857 are now always initialized with the +over proj4
option to prevent distortions at the dateline
