Detailed notes:

Meshtools

The meshtools module has been extensively revised with many new features:

• New MeshPruner class added that enables coarsening of meshes, analogous to MeshRefiner.
• Refinement of 3D elements.
• Refinement of selections is improved.
• Bugfixes for MeshRefiner and MeshMerge to prevent duplicate elements being generated in some circumstances.

Text

The morphoview application now supports text rendering. A number of modules have been updated to take advantage of this:

• plot now provides ScaleBar objects that are useful for plotfield, as well as plotmeshlabels to label a mesh with element ids.
• graphics now provides a Text class for textual elements, and has some performance improvements.
• color now provides a number of new ColorMaps: ViridisMap, InfernoMap, MagmaMap and PlasmaMap, all of which are more friendly for people with color vision deficiency.

Variadic functions

You can now create functions that accept a variable number of parameters. Arguments passed to a function can be accessed as a List.

fn func(x, ...v) {
    for (a in v) print a
}

Other improvements:

• New VolumeIntegral module to complement AreaIntegral and LineIntegral.
• Internal improvements to the morpho virtual machine.
• A System class to enable you to get platform information.
• Numerous bugfixes.
• Numerous improvements to the documentation.
• Improvements to the povray module.
• New examples for plot module.
