• Added the ability to disable the need for various dependencies: proj4, libpng, libtiff, libjpeg

• Added faster reprojection support between epsg:3857 and epsg:4326 (#1705,#1703,#1579)

• Fixed concurrency problem when using cursors in postgis plugin (#1823,#1588)

• Fixed postgres connection pool leaks when using persist_connection=false (#1764)

• Fixed postgres connection key to respect highest value of max_size and initial_size for any layer in map (#1599)

• Fixed potential crash in wkb parsing when postgis returns null geometry (#1843)

• Fixed blurry rendering of image and SVG icons (#1316)

• Added detection of invalid srs values when loading xml (#646)

• Added support for specifying a base_path as a third, optional argument to load_xml

• Removed muffling of projection errors while rendering (#646)

• Improved logging system (https://github.com/mapnik/mapnik/wiki/Logging)

• Added support for reading images from in memory streams (#1805)

• Optimized halo rendering. When halo radius is < 1 new method will be used automatically (#1781)

• Added text-halo-rasterizer property. Set to fast for lower quality but faster halo rendering (#1298) which matched new default method when radius is < 1.

• Added support in shape, sqlite, geojson, and csv plugin for handling non-latin characters in the paths to file-based resources (#1177)

• Fixed rendering of markers when their size is greater than the specified spacing value (#1487)

• Fixed handling of alpha premultiplication in image scaling (#1489)

• Optimized rendering when a style with no symbolizers is encountered (#1517)

• Optimized string handling and type conversion by removing boost::to_lower, boost::trim, and boost::lexical_cast usage (#1687,#1687,#1633)

• Optimized alpha preserving hextree method for quantization of png images (#1629)

• Faster rendering of rasters by reducing memory allocation of temporary buffers (#1516)

• Fixed some raster reprojection artifacts (#1501)

• Fixed raster alignment when width != height and raster is being scaled (#1748,#1622)

• Added support for caching rasters for re-use during rendering when styling more than once per layer (#1543)

• Improved compile speeds of the code - in some cases by up to 2x and removed need for freetype dependency when building code against mapnik (#1688, #1756)

• Removed internal rule cache on mapnik::Map c++ object (#1723)

• Improved the scaled rendering of various map features when using scale_factor > 1 (#1280,#1100,#1273,#1792,#1291,#1344,#1279,#1624,#1767,#1766)

• Added C++ api for overriding scale_denominator to enable rendering at fixed scale (#1582)

• Added Layer buffer-size that can be used to override Map buffer-size to avoid over-fetching of data that does not need to be buffered as much as other layers. Map level buffer-size will be default if layers do not set the option. Renamed a previously undocumented parameter by the same name that impacted clipping extent and was not needed (clipping padding should likely be a symbolizer level option) (#1566)

• Fixed potential file descriptor leaks in image readers when invalid images were encountered (#1783)

• Fixed alpha handling in the blur and invert image filters (#1541)

• Fixed error reporting in the python plugin (#1422)

• Added the ability to run tests without installing with make test-local

• Reduced library binary size by adding support for -fvisibility-inlines-hidden and -fvisibility=hidden (#1826,#1832)

• Added mapnik::map_request class, a special object to allow passing mutable map objects to renderer (#1737)

• Added the ability to use boost::hash on mapnik::value types (#1729)

• Removed obsolete geos plugin (functionality replaced by csv plugin) and unmaintained kismet plugin (#1809,#1833)

• Added new mapnik-config flags: --all-flags, --defines, --git-describe, --includes, --dep-includes, --cxxflags, --cxx (#1443)

• Added support for unicode strings as arguments in python bindings (#163)

• Added DebugSymbolizer which is able to render the otherwise invisible collision boxes (#1366)

• Optimized rendering by reducing overhead of using gamma property (#1174)

• Fixed rendering artifacts when using polygon-gamma or line-gamma equal to 0 (#761,#1763)

• Fixed and optimized the display of excessive precision of some float data in labels (#430,#1697)

• Removed the bind option for datasources (#1654)

• Added ability to access style list from map by (name,obj) in python (#1725)

• Added is_solid method to python mapnik.Image and mapnik.ImageView classes (#1728)

• Changed scale_denominator C++ interface to take scale as first argument rather than map.

• Added support for background-image in cairo_renderer (#1724)

• Fixed building symbolizer rendering to be fully sensitive to alpha (8b66128c89 / bc8ea1c5a7)

• <Filter>[attr]</Filter> now returns false if attr is an empty string (#1665)

• <Filter>[attr]!=null</Filter> now returns true if attr is not null (#1642)

• Added support for DBF Logical type: #1614

• Added serialization of line-offset to save_map (#1562)

• Enabled default input plugin directory and fonts path to be set inherited from environment settings in python bindings to make it easier to run tests locally (#1594). New environment settings are:

  • MAPNIK_INPUT_PLUGINS_DIRECTORY
  • MAPNIK_FONT_DIRECTORY

• Added support for controlling rendering behavior of markers on multi-geometries marker-multi-policy (#1555,#1573)

• Added alternative PNG/ZLIB implementation (miniz) that can be enabled with e=miniz (#1554)

• Added support for setting zlib Z_FIXED strategy with format string: png:z=fixed

• Fixed handling of transparency level option in octree png encoding (#1556)

• Added ability to pass a pre-created collision detector to the cairo renderer (#1444)

• Tolerance parameter is now supported for querying datasources at a given point (#503/#1499)

• Improved detection of newlines in CSV files - now more robust in the face of mixed newline types (#1497)

• Allow style level compositing operations to work outside of featureset extents across tiled requests (#1477)

• Support for encoding literal postgres types as strings 69fb17cd3/#1466

• Fixed zoom_all behavior when Map maximum-extent is provided. Previously maximum-extent was used outright but now the combined layer extents will be again respected: they will be clipped to the maximum-extent if possible and only when back-projecting fails for all layers will the maximum-extent be used as a fallback (#1473)

• Compile time flag called PLUGIN_LINKING to allow input datasource plugins to be statically linked with the mapnik library (#249)

• Fixed dasharray rendering in cairo backend (#1740)

• Fixed handling of opacity in svg rendering (#1744)

• Fixed uneven rendering of markers along lines (#1693)

• Added experimental support for geometry simplification at symbolizer level (#1385)
