Summary

- The `shapeindex` command now has a `--index-parts` option. When used the index will be bigger
but will allow the Shapefile datasource to only parse polygon parts within the query bounds.
- WARNING: index files generated with this newer Mapnik are invalid for older versions of Mapnik.
- Any `.index` files accompanying a `.shp` must now be regenerated otherwise
it will be skipped. To avoid this problem you can delete the existing `.index` files, or ideally run `shapeindex` to recreate the `.index`. (https://github.com/mapnik/mapnik/pull/3300)
The trigger for this change was an optimization that required a new binary format for the shapefile indexes (https://github.com/mapnik/mapnik/pull/3217).
- Shapeindex - another fix for skipping `null` shapes (3288)
- Fixed support for filter expressions starting with `not` (https://github.com/mapnik/mapnik/issues/3017)
- Ensure `mapped_memory_cache` acts as singleton across shared objects (3306)
- Removed miniz support in PNG encoder (3281)
- Added `-fvisibility=hidden -fvisibility-inlines-hidden` to default compiler flags
- Fixed parsing of SVG `PathElement` (https://github.com/mapnik/mapnik/issues/3225)
- JSON parsing now supports arbitrary (nested) attributes in `geometry`
- Support for rendering `dash-array` in SVGs
- SVG parser is now stricter (fails is all input is not parsable) (3251)
- SVG parser now correctly handles optional separator `(,)` between multiple command parts
- Optimized parsing of `png` format string
- The `memory_datasource` now dynamically reports correct datasource type (vector or raster)
- Upgraded `mapbox::variant v1.1.0`
- Compare: https://github.com/mapnik/mapnik/compare/v3.0.9...v3.0.10

- Increased unit test coverage for GeoJSON and CSV plugins
- shape.input - re-factor to support *.shx and improve handling various bogus shapefiles
