## [0.1.0] - 2024-02-09

### Added

- (#18) Implemented Cocircuits and covectors.
- (#14) Added some additional examples to ensure tests catch potential errors.

### Changed

- (#22) Updated the documentation to be more complete.
- (#12) Altered it so that the `to_xxx()` functions are encapsulated in the function `change_type()`.
- (#2) Updated package to fit into up to date methods for making packages.
- (#1) Restructed the OrientedMatroids class. In particular:

- (#15) Fixed the groundset error bug.


## [0.0.2] - 2020-12-15

### Added

- Can now add point configurations

### Changed
