3.0.0 2024-08-27
~~~~~~~~~~~~~~~~

Breaking:

  - Add proper XML Exception when service parameter disabled / invalid or missing
    In the past MapProxy returned WMS Capabilities when no explicit service parameter was given in
    GetCapabilities requests. With this change, an OGC exception will be returned instead.
    Invalid service types now also return a proper exception instead of an `internal error`.
    Besides, the status code of exception responses now have a 400 or 500 code instead of 200
    for better conformity.

Improvements:

- concurrent_requests limit is now per unique hostname and not per URL
- concurrent_requests can be set with globals.http.concurrent_requests
- font_size of watermark is now configurable
- improved configuration loading time and memory consumption
- make use of PyYAML's C extension if available
- cache projection attributes in SRS objects for better performance
- try system wide projection definitions first, then fallback to defaults
  (e.g. for EPSG:900913)
- trailing slash is now optional for /tms/1.0.0
- support for http.ssl_ca_cert for each WMS source
- support for http.client_timeout for each WMS source (Python >=2.6)

0.9.0 2010-10-18
~~~~~~~~~~~~~~~~

- minor bug fixes

0.9.0rc1 2010-10-13
~~~~~~~~~~~~~~~~~~~

- 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.
- updated tempita to 0.5

0.9.0b2 2010-09-20
~~~~~~~~~~~~~~~~~~

- new minimize_meta_requests option
- moved python implementation dependent code to mapproxy.platform module

0.9.0b1 2010-08-30
~~~~~~~~~~~~~~~~~~

- Improved support for EPSG:3857
- Source requests now never go beyond the grid BBOX even with meta_buffers/meta_tiles
- removed install_requires
  - flup: not required for all deployment options
  - tempita: now embeded
- now Python 2.7 compatible
- [mapproxy-seed] fixed libgdal loading on some Linux systems
- [mapproxy-seed] check for intersections on all levels
- add origin options to /tiles service to support Google Maps clients
- Improved PNG performance with PIL fastpng branch.
- New concurrent_requests option to limit requests for each source WMS server.
- minor bug fixes

0.9.0a1 2010-07-27
~~~~~~~~~~~~~~~~~~

- new configuration format (merged proxy.yaml and service.yaml)
- refactoring of the caching (sources and layers)
- large refactoring of the package layout

- pyproj dependency is not required when libproj is available
- removed jinja dependency

- more options to define tile grids (min_res, max_res, etc.)

0.8.4 2010-08-01
~~~~~~~~~~~~~~~~

- Extra newline at the end of all templates. Some deployment setups
  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-
  Authentication.
- 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
  Supports url templates like '/tiles?x=%(x)s&y=%(y)s&level=%(z)s'
  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.

0.8.3rc1 2010-04-30
~~~~~~~~~~~~~~~~~~~

- new improved seed tool

  - seed polygon areas instead BBOX (from shapefiles, etc)
  - advanced seeding strategy
  - multiprocessing

- new link_single_color_images layer option. multiple "empty" tiles will
  be linked to the same image. (Unix only)
- fixed transparency for image parts without tiles
- log HTTP requests to servers regardless of the success
- made proj4 data dir configurable
- use same ordering of layers in service.yaml for capabilities documents
  (use list of dicts in configuration, see docs)
- performance improvements for requests with multiple layers and
  for layers with smaler BBOXs

0.8.2 2010-04-13
~~~~~~~~~~~~~~~~

- no changes since 0.8.2rc1

0.8.2rc1 2010-04-01
~~~~~~~~~~~~~~~~~~~

- add fallback if PIL is missing TrueType support
- use zc.lockfile for locking

  (same srs and same resolution) #4

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

- initial release
