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

  • Added transform3 (transform using 4x4 matrix representing affine transformation) #410
  • 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
