`moonlight-triangulation` follows the
[Haskell Package Versioning Policy](https://pvp.haskell.org).

The serialization format carries its own version tag, independent of the package
version; any change to it is recorded here explicitly.

## 0.2.0.0

* Specialize the public geometry surface to binary64 and remove the ornamental
  scalar parameter from points, queries, triangulations, sessions, hierarchy
  hints, interpolation workspaces, and result types.
* Add dense coordinate and inner-face vertex projections to the existing DCEL
  surface.
* Add exact support relations and finite-set operations over triangulations,
  with local publication for sparse differences, intersections, and symmetric
  differences.
* Schedule singleton insertion and constrained extension between dense and
  locality-preserving transactions from measured workload evidence.
* Resolve dense coordinate-removal batches through one mutable identity index,
  retaining geometric descent for sparse removals.
* Strengthen constrained extension, refinement, serialization, algebra, and
  hostile-boundary validation.

## 0.1.0.0

* Initial release.
