    Release Notes: This is the alpha release unveiling of Archer/MGED, a preliminary interface update to BRL-CAD's graphical geometry editor. Some highlights include an integrated graphical tree view, a single window framework, drag-and-drop geometry editing, information panels, shortcut buttons, improved polygonal mesh and 2D sketch editing, a level of detail wireframes, and NURBS shaded display support.

      Release Notes: This is a substantial introduction of a new development line encompassing more changes than any prior version since BRL-CAD became free open source software. It has robust solid NURBS ray tracing, fixes everything reported by Coverity, updates several geometry converters, has work on a new physics simulation system, makes several improvements to BRL-CAD's extensive documentation resources, and provides a vastly improved installer for Mac OS X.

        Release Notes: This release provides several dozen major feature enhancements and fixes. Support for NURBS continues to improve with better STEP import, ray tracing fixes, better wireframes, and numerous robustness improvements. MGED/Archer continues to approach alpha status with support added for interactive pipe editing, improved visualization, new mesh healing capabilities, and more. After many months of effort, the OBJ importer receives a comprehensive overhaul improving polygonal mesh import. There is a new exporter to the DOT format used by Graphviz for graphic visualization of geometry hierarchies.

          Release Notes: This release marks the introduction of a new CMake-based build system. Improvements continue on geometry conversion and tessellation to polygonal formats. Progress was made merging MGED and Archer for an upcoming combined alpha with numerous command improvements, bug fixes, and interface enhancements. Experimental enhancements to BRL-CAD's rending system are also under development in support of programmable shaders.

            Release Notes: This release includes numerous bugfixes and feature enhancements to MGED, geometry converters, image processing tools, and more. This release includes the initial (yet phenomenally impressive) integration of the high-performance Triangle Intersection Engine (TIE) with BRL-CAD's LIBRT raytrace library. There is a new geometry importer for Shapefile data, and the revolve primitive receives support for transformation matrix editing.

              Release Notes: The biggest change provided in this release is support for reading older (platform-dependent) binary v4 geometry database files regardless of their originating platform. MGED receives several changes, including a fix for a bug that was causing text edit commands to fail. MGED will now also display attributes sorted by name for improved readability. There were numerous platform integration and usability enhancements for Debian, Ubuntu, Fedora, and other Linux platforms, including new desktop icons, menu items, MIME type associations, and much more.

                Release Notes: This release further improves support for NURBS raytracing and with raytrace robustness improvements and better wireframe display. MGED improvements include fixes to the "nirt", "ident", "solids", and "regions" commands. The "rt" command can now output in the PNG format. NMG/Bot tessellation robustness has improved and Spanish versions of all 16 MGED tutorials are included.

                  Release Notes: More than 50 bugfixes, minor enhancements, and other user-visible changes were made. Ray tracing support for NURBS/BREP multiple-representation geometry continues to improve with ray tracing fixes, robustness improvements, and trimming enhancements. Numerous MGED bugs were fixed, including the Mac input bug, restoration of previous behavior, and continued Archer feature integration. MGED's wireframe display gets a substantial 5x-10x performance improvement and improved 64-bit compilation support for Windows.

                    Release Notes: Considerable effort continues to go into improving the documentation, with more than 200 commands converted to Docbook XML and 4 of MGED's 16 tutorials translated into Spanish. This release adds support for bulk renaming of geometry objects, includes numerous bugfixes to processing commands that manage region identifiers, and improves triangle mesh (BoT) ray tracing.

                      Release Notes: Included are updates to MGED's gqa, garbage_collect, view, and bot_dump commands. The benchmark suite provides extensive system information in the summary report. The STEP geometry importer continues to be enhanced. Translation of the BRL-CAD documentation (the tutorial series) to Spanish is underway with several lessons now completed. This release update provides a number of other minor enhancements and bug fixes to BRL-CAD tools as well.
