+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+
+## [Unreleased]
+
+### Changed
+
+- Implemented a more efficient internal parametric transformation for `Meshes.Tetrahedron`, resulting in about an 80% integral performance improvement.
+
+
+## [0.16.0] - 2024-12-14
+
+### Added
+
+- Added a `diff_method` keyword argument to the `integral` API, allowing the user to specify which differentiation method should be used when calculating differential element magnitudes throughout the integration domain.
+- Implemented `DifferentiationMethod` types:
+    - `FiniteDifference` for finite-difference approximation.
+    - `AutoEnzyme` for using [Enzyme.jl](https://github.com/EnzymeAD/Enzyme.jl) automatic differentiation (AD) via a package extension.
+- Added `diff_method` as an optional third argument to the `jacobian` and `differential` API.
+- Adds standardized support for integrating over `Tetrahedron` volumes.
+- Generalizes integrand functions to support any `f::Any` with a method defined for `f(::Point)`.
+- Refactored specialization methods by implementing an internal `_ParametricGeometry <: Meshes.Geometry` to define geometries with custom parametric functions, standardizing support for `BezierCurve`, `Line`, `Plane`, `Ray`, `Tetrahedron`, and `Triangle`.
+- Significant performance improvements:
+  - Achieved an 80x improvement when integrating over `BezierCurve`.
+  - Achieved an up-to-4x improvement when integrating using `HAdaptiveCubature`.
+
+### Deprecated
+
+- Deprecated manual specification of `GaussKronrod` rules for surfaces, i.e. geometries where `Meshes.paramdim(geometry) == 2`. A warning is now generated recommending users switch to `HAdaptiveCubature`.
+
+### Fixed
+
+- Refactored the unit test system.
+  - Standardized `combinations.jl` tests by constructing a `TestableGeometry` package and passing it to a `@test` generation function to provide more thorough and standardized test coverage.
+  - Reorganized `@testsnippet`s to exist in same source file as relevant tests.
+  - Removed `:extended` tag from `Tetrahedron` now that performance is significantly improved.
+
+
+## [0.15.2] - 2024-10-25
+
+MeshIntegrals.jl is now owned by the JuliaGeometry organization!
+
+### Added
+
+- Added a benchmarking suite using [AirspeedVelocity.jl](https://github.com/MilesCranmer/AirspeedVelocity.jl).
+- Implemented more unit tests with analytical solutions.
+
+### Changed
+
+- Tagged unit tests for `Meshes.Box` (4D) and `Tetrahedron` as `:extended`, removing them from automatic CI testing due to lengthy compute times.
+
+
+## [0.15.1] - 2024-10-11
+
+### Added
+
+- Adds official support and unit testing for integrating new `Meshes.ParametrizedCurve` geometries.
+
+
+## [0.15.0] - 2024-10-10
+
+### Added
+
+- Adds support for integrating geometries with any number of parametric dimensions by generalizing `differential` to n-dimensions via geometric algebra.
+- Adds official support and unit testing for integrating `Meshes.Ellipsoid` and `Meshes.Hexahedron` geometries.
+
+### Changed
+
+- Refactored the unit test system.
+    - Completed transition away from previous `@test` generation system which only tested unit integrands (i.e. `f(point) = 1.0`) using `Meshes.measure` as a benchmark.
+    - Used [TestItems.jl](https://github.com/julia-vscode/TestItems.jl) to define independent `@testitem` packages, many with analytically-derived solutions.
+
+
+## [0.14.1] - 2024-10-04
+
+### Added
+
+- Adds official support and unit testing for integrating `Meshes.Quadrangle` geometries.
+
+### Changed
+
+- Continued work transitioning away from previous `@test` generation system.
+
+### Fixed
+
+- Fixed a bug in `differential` finite-difference approximation that may have reduced accuracy of some integral calculations.
+- Made improvements to type stability with floating point type keyword argument `FP`.
+
+
+## [0.14.0] - 2024-09-28
+
+### Changed
+
+- Rename `IntegrationAlgorithm` to `IntegrationRule` and consolidate terminology around integration rules (versus "algorithms", "settings", etc).
+- Convert floating point precision option `FP` from an optional argument to a keyword argument.
+- Continued work transitioning away from previous `@test` generation system.
+
+### Removed
+
+- Remove `derivative` and `unitdirection` functions. All `derivative` functionality was merged into `jacobian`.
