Dear OpenSCAD users and developers,

OpenSCAD 2019.05 has just been released: http://www.openscad.org/news.html#20190518

This release adds a number of features which have been in development for the last 4 years. Some of the larger program features are Customizer, which was first started as a Google Summer of Code project, and 3D input device support. The OpenSCAD language itself and standard library has seen a number of iterative improvements

The source code, as well as binaries for Mac OS X, Windows and Linux are ready for download.

As usual, thanks go to everyone who has contributed to this release through development and community management, bug reports and fixes, documentation, translation, discussions, as well as testing the development snapshots!

A summary of changes since last release follows.

Take care,

-Marius
