2014.03

Language Features:

• Added diameter argument: circle(d), cylinder(d, d1, d2) and sphere(d)
• Added parent_module() and $parent_modules
• Added children() as a replacement for child()
• Unicode strings (using UTF-8) are now correctly handled
• Ranges can have a negative step value
• Added norm() and cross() functions

Program Features:

• Cmd-line: --info parameter prints system/library info
• Cmd-line: --csglimit parameter to change CSG rendering limit
• Cmd-line: Better handling of cmd-line arguments under Windows
• GUI: Added Reset View
• GUI: Added Search&Replace in editor
• GUI: Syntax highlighting now has a dark background theme
• GUI: We now create a backup file before rendering to allow for recovery if OpenSCAD crashes/freezes
• GUI: Accessibility features enabled (e.g. screenreading)

Bugfixes/improvements:

• Reading empty STL files sometimes caused a crash
• OPENSCADPATH now uses semicolon as path separator under Windows
• polyhedron() is now much more robust handling almost planar polygons
• Automatic reloads of large designs are more robust
• Boolean logic in if() statements are now correctly short-circuited
• rands() with zero range caused an infinite loop
• resize(, auto=true) didn't work when shrinking objects
• The $children variable sometimes misbehaved due to dynamic scoping
• The --camera cmd-line option behaved differently then the corresponding GUI function
• PNG export now doesn't leak transparency settings into the target image
• Improved performance of 3D hull() operations
• Some editor misbehaviors were fixed
• Stability fixes of CGAL-related crashes
• Windows cmd-line can now handle spaces in filenames
• Default CSG rendering limit is now 100K elements
• Fixed a crash reading DXF files using comma as decimal separator
• Fixed a crash running the cmd-line without a HOME env. variable
• Intersecting something with nothing now correctly results in an empty object

Deprecations:

• child() is no longer supported. Use children() instead.
• polyhedron(triangles=[...]): Use polyhedron(faces=[...]) instead.

Misc:

• Test framework now shares more code with the GUI app
• Test report can now be automatically uploaded to dinkypage.com
• Better compatibility with BSD systems
• Qt5 support
