## [Unreleased]
### Added
- equals operator for `Label` class
- package metadata: added link to changelog

### Removed
- compatibility with `python3.6`

## [2.0.0] - 2021-05-22
### Removed
- compatibility with `python3.5`

### Changed
- added default value for `creator` to fix `TypeError` in `write_triangular` when unset
- `write_triangular`: raise descriptive `ValueError` when missing `volume_geometry_info`
  (instead of `TypeError`)
- `find_label_border_polygonal_chains`: raise descriptive `RuntimeError`
  when annotation was not loaded (instead of `TypeError`)

### Fixed
- fixed type hints

## [1.2.0] - 2021-01-02
### Added
- GPLv3+ license
- method `PolygonalCircuit.normalized()`

### Fixed
- `Surface.find_label_border_polygonal_chains`:
  always include vertices along border with single neighbour
  (previously indeterministic behaviour)
- `PolygonalCircuit`: fix equals operator for circuits
  with different but equivalent vertex orders
- type hints

## [1.1.1] - 2020-10-18
### Fixed
- fix `ModuleNotFoundError` on `import freesurfer_surface.version`
  for developers not installing package
  (https://github.com/fphammerle/freesurfer-surface/issues/22)
- `setlocale`: re-raise original exception
  when the selected locale is not supported

## [1.1.0] - 2019-05-23
### Added
* added static method `Surface.unite(surfaces)`
* added command-line entry point / script `unite-freesurfer-surfaces`

## [1.0.1] - 2019-05-23
### Fixed
- `Surface.find_borders()` failed on self-crossing borders

## [1.0.0] - 2019-05-19
## Added
- method `Surface.find_borders()`
- method `Surface.remove_unused_vertices()`
- method `Surface.select_vertices(vertex_indices)`
- method `Vertex.distance_mm(other_vertices)`
- class `LineSegment`
- class `PolygonalCircuit`

## Changed
* property `Triangle.vertex_indices` is now read-only

## [0.2.2] - 2019-05-19
### Fixed
- fixed comparison & hashing of `Triangle` / `_PolygonalCircuit`
  (`_PolygonalCircuit._normalize` now considers order of indices)

## [0.2.1] - 2019-05-16
### Fixed
- fix formatting of project description on pypi

## [0.2.0] - 2019-05-15
### Added
- added `PolygonalChain.adjacent_vertex_indices()`
- `Surface.add_rectangle`: accept 3 or 4 vertex indices (previously only 3)

### Changed
- derive `Vertex` from `numpy.ndarray` (previously `collections.namedtuple`)

### Fixed
* `Surface._find_label_border_segments`: failing on incompletely labelled set of vertices

## [0.1.0] - 2019-05-12
