----------------------------------------------------------------------
--- 2020-09-14  Release 7.32.0                                     ---
----------------------------------------------------------------------

This major release of BRL-CAD introduces significant updates to core
library infrastructure.  The update includes restructuring of nearly
all of BRL-CAD's display infrastructure in preparation for upcoming
significant GUI changes.  This release also fixes over fifty of
BRL-CAD's command-line utilities so they work properly on Windows.
This is likely the last major release of BRL-CAD on Subversion
infrastructure with BRL-CAD's imminent migration to Git.

--- 2019-02-25  Release 7.30.0                                     ---
----------------------------------------------------------------------

This major release of BRL-CAD is the first release requiring
compiler support for the C++11 language standard when building.
(This change is not user visible, but will be significant to those
using BRL-CAD in their own software development efforts.)

This release introduces a new "-d" option to the mater command,
supporting direct embedding of .density file information in a
.g database for use by commands such as gqa and rtweight.

Also present in this release are a fix for commands that work with
multiple .g files and support for raytracing MGED scenes with large
numbers of active objects.

A number of commands and tools previously listed as deprecated are
removed in this release, including in particular MGED commands
specific to MUVES.

* added rtweight -d option for specifying density file - Cliff Yapp
* added material density management to "mater" command - Cliff Yapp
* use full paths for OBJ objects in "bot dump" command - Cliff Yapp
* added -v high precision option to MGED 'center' command - Cliff Yapp
* fixed crash when using dbconcat and dup together in MGED
        - Cliff Yapp, Sean Morrison
* renamed MGED "ps" command to "postscript" - Cliff Yapp
* removed MGED commands em, e_muves, l_muves, lm, read_muves, t_muves
        - Cliff Yapp
* removed deprecated irprep tools - Cliff Yapp
* removed deprecated fbed and pp-fb framebuffer tools - Cliff Yapp
* fixed rt support for specifying large object lists - Cliff Yapp

BRL-CAD 7.28.0

----------------------------------------------------------------------
--- 2018-10-01  Release 7.28.0                                     ---
----------------------------------------------------------------------

This major release of BRL-CAD incorporates a new feature for caching
of raytrace acceleration structures used when working with explicit
boundary representation (BREP) Non-uniform Rational Basis Spline
(NURBS) solids.  This will result in significant improvements to
run times when repeatedly raytracing BREP solids.

Support for terrain import has been significantly expanded with the
addition of a new Geospatial Data Abstraction Library (GDAL) based
importer to the gcv conversion tool.  GDAL brings with it support for
dozens of different terrain data formats.

Also new in this release are a greatly improved graphical geometry
overlap resolving tool and support in the MGED search command for
an "exec" option which will allow users to execute MGED commands
on search results.

The MGED facetize command for generating polygonal geometry from
BRL-CAD objects has received significant attention, including the
incorporation of a "per-region" conversion mode, new conversion
methodologies and usability enhancements.
