Version 0.4.0.0 (2022-06-06)

Changelog started. Previous release was 0.3.0.1.
Haskell interface changes
- Added support for XY-scaling on linear_extrude #269
  - ExtrudeRM scale type changes from (Either ℝ (ℝ -> ℝ)) to ExtrudeRMScale
- Replaced the Rect primitives with SquareR and CubeR #296
  - squareR and cubeR are now available
- Added support for mirroring objects around axis using mirror function #300
- differenceR changes type to require mandatory shape to substract from #294
  - from Object obj vec => R -> [obj] -> obj
  - to Object obj vec => R -> obj -> [obj] -> obj
- Both SymbolicObj2 and SymbolicObj3 now have Semigroup and Monoid instances, where <> acts as union #301
- Added rotateQ function for rotating with Quaternions #314
- ℝ2 and ℝ3 are now using V2 and V3 from linear instead of tuples #342
- Rounding is now separate from primitives #362
  - Introduces withRounding function.
  - Instead of primitiveR roundingValue ... we now use withRounding roundingValue (primitive ...)
  - Replaces squareR, rectR, polygonR, cubeR, rect3R, extrudeR, extrudeRM with versions without rounding arugment (square, rect, ...).
- Removed ExtrudeRotateR #365

- Changed Object obj vec class to Object obj f a #420
ExtOpenSCAD interface changes
- scale function with single parameter now behaves similar to OpenSCAD one #258
  - scales 2D object in both dimensions
- rotateExtrude angle a parameter renamed to angle to match OpenSCAD #259
- Added mirror support #300
- Added multmatrix support #410
Other changes

- implicitsnap not built by default anymore #272
  - Can be enabled again with cabal configure --flag=implicitsnap
- Fixed vertex coordinates of OBJ output #281
  - discreteAprox of NormedTriangleMesh now runs in parallel #282
- Binaries now built with default -rtsopts "-with-rtsopts -N -qg -t" to allow automatic parallelization
- Added haddocks for Haskell eDSL #284 & #287
- Added golden test machinery #311
