Version 2.0.0

In development

  • Drop Python 2 support
  • Usage of tox for tests
  • Add GitHub Actions
  • Add pre-commit tool
  • Regenerate the vector tile protobuf Python code to solve #113
  • Support for Python 3.11
  • Delete the round_fn argument as Python 2 has been dropped
  • Use pyproject.toml and Poetry to replace the setup.py file

Version 1.2.1

  • Add the trove classifiers to the setup.py

Version 1.2.0

  • Performance focused release, including:
  • Enable Shapely speedups, when available
  • Skip inners which cause exceptions
  • Union inners in blocks when making valid
  • Make benchmark script python3 compatible
  • Fix test to support different versions of GEOS

Version 1.1.0

  • Include LICENSE & CHANGELOG.md in sdist tarballs
  • Refactor geometry encoding logic, including skipping tiny geometries
  • Decoded geometry is now geojson-ish dict
  • Winding order is now optional
  • Add benchmarking around round function and document how to improve performance
  • Document performance tip for protobuf encoding with C bindings for Debian

Version 1.0.0

  • Generate more valid polygons and multipolygons using pyclipper library for v2 MVT compliance (but we're still not fully v2 compliant for other reasons).
  • Handle edge cases where polygon buffer makes a multi-polygon, ensuring inner rings are dropped when subtracting them from the polygon would make it invalid, and not adding multipolygons as array elements for multipolygon constructor.
  • Calculate area more properly by using PolyTree result from Clipper.
  • Factor out polygon validity code into its own file.

Version 0.5.0

  • Improved results from on_invalid_geometry_make_valid when the geometry is self-crossing. It was possible for large parts of the geometry to be discarded, and it is now less likely. See PR 66 for more information.

Version 0.4.0

  • Custom rounding functions: a round_fn parameter was added to the encode function, which allows control over how floating point coordinates are transformed to integer ones. See PR 55.
  • Custom validity functions: an on_invalid_geometry parameter was added to the encode function, which is called when invalid geometry is found, or created through coordinate rounding. See PR 46.
  • Winding order bug fix: See issue 57 and PR 59.
  • Performance improvements: including a 2x speedup from using tuples instead of dicts for coordinates, see PR 56.
  • Improvements to PY3 compatibility: See PR 52.

Version 0.3.0

  • python3 compatability improvements
  • travis integration
  • documentation updates
  • insert CMD_SEG_END for MultiPolygons
  • decode multipolygons correctly
  • encode tiles using version 1

Version 0.2.1

  • include README.md in distribution to fix install

Version 0.2.0

  • python3 updates
  • enforce winding order on multipolygons
  • update key/val handling
  • round floating point values instead of truncating
  • add option to quantize bounds
  • add option to flip y coord system
  • add ability to pass custom extents

Version 0.1.0

  • Add compatibility with python 3
  • Handle multipolygons as single features
  • Use winding order from mapbox vector tile 2.0 spec
  • Support custom extents when decoding

Version 0.0.11

  • Decode string keys to utf-8

Version 0.0.10

  • Allow encoder to accept shapely objects directly

Version 0.0.9

  • Handle tiles from java-vector-tile (zero pad binary integers)
  • Update README

Version 0.0.8

  • Handle unicode properties

Version 0.0.7

  • Update id handling behavior

Version 0.0.6

  • Explode multipolygons into several features
  • #4
  • Resolve issue when id is passed in
  • More tests

Version 0.0.5

  • Removing the option of encoding floats in big endian
  • Updated tests

Version 0.0.4

  • Bug fix - does not try to load wkt geom if wkb succeeds

Version 0.0.3

  • Option to encode floats in little endian

Version 0.0.2

  • WKT Support
  • Better Documentation
  • More tests

Version 0.0.1

  • Initial release
