- In C++ `mapnik::Map::getLayer` was changed to `mapnik::Map::get_layer`
- Changed `polygon_pattern_symbolizer` to default to `global` rather than `local` for the `alignment`.
- CSV plugin now parses and stores the strings of `"true"`, and `"false"` as boolean types (rather than strings) - https://github.com/mapnik/mapnik/issues/1540
- Default PNG output now is paletted using the high quality alpha-preserving `hextree` encoder (what used to be only possible with `png8:m=h`. This is now triggered when the `png` format string is used. Use `png32` to maintain rendering of full color rgba images as previously. More details at [this ticket](https://github.com/mapnik/mapnik/issues/2028) and [[Image-IO]]
## Added
- `MarkersSymbolizer` now supports `offset`, `geometry-transform`, `simplify` for `line` placement and two new `placement` options called `vertex-last` and `vertex-first` to place a single marker at the end or beginning of a path. Also `clip` is now respected when rendering markers on a LineString geometry.
