Postby thawkins » 2015-Mar-Tue-17-Mar

Dear OpenSCAD users and developers,

OpenSCAD 2015.03 has just been released: http://www.openscad.org/news.html#20150310

This release adds a number of features which has been in development for some time. Most prominent are text(), offset() and list comprehension functionality, as well as a better editor and other GUI improvements implemented during last year’s Google Summer of Code.
A summary of changes since last release follows.

The source code, as well as binaries for Mac OS X, Windows and Linux can be downloaded from http://openscad.org.

Lots of thanks go to everyone who have contributed to this release through development, translation, bug reports, bug fixes, documentation, discussions, as well as testing the development snapshots!

Take care,

-Marius
