MGED has a powerful new 'search' command that is very similar to the UNIX find command but specifically tailored to geometry hierarchies. This release also provides a preview of many documentation improvements to come with the start of a new command help system within MGED. Other developments include numerous improvements to the Pro/E export plugin, the height field (DSP) primitive can now be exported to other geometry file formats, and much more. The INTAVAL importer is now fully integrated into BRL-CAD and included in the default install too.
