 Fixed issue with vchars.mta and symbols.mta not being installed in
 the appropriate metafile library location, with help from Rob G.
+
+Added ability to give quoted strings to output= directive in rfluxmtx.
+
+****** COMPATIBILITY CHANGE ********
+Added ability to digest color (CIE-XYZ) input in pabopto2bsdf.
+This change alters the .sir (interpolant) format, so these files
+will need to be regenerated.  Use the new "#colorimetry: CIE-XYZ" tag
+to enable on input.
+
+Rewrote bsdf2klems to support tristimulus color and call wrapBSDF.
+Did the same for bsdf2ttree.  Function specifications still gray only.
+
+Reduced a problem where rvu or rholo would be slow to quit when
+run with many processes on a large model or one with a large
+ambient file (taking lots of memory).  We were waiting for
+processes to quit one-by-one, which takes some time for each
+process as it disentangles its shared memory.  We now
+wait for all the processes together, so they can disentangle
+in parallel.  It can still take up to a minute in some cases,
+but not 10 minutes like it was taking before the fix.
+
+Enabled ambient cache value corral for all levels, not just final two.
+This may reduce errors in certain pathological scenes.
+
+Added -in option to rcalc, rlam, and total to limit the number of
+input records in hopes of circumventing Windows EOF issues on binary data.
+Also added -on option to rcalc and total for logical symmetry.
+
+Increased modifier limit to 10,000 in rcontrib.
+
+Fixed issues with glrad and added zoom response to mouse wheel input.
+
+Added missing definition of "ashik2" material type to reference manual.
+
+Changed genBSDF to calculate device thickness assuming Zmax==0 so
+pkgBSDF will generate correct proxy geometry.
+
+Created pabopto2xyz tool to combine different sensor measurements
+into a single CIE-XYZ measurement file for color BSDF interpolation.
+
+Jan Wienold updated evalglare to version 1.30
+
+Roland Schregle added out-of-core photon mapping routines, which
+may be compiled using the PMAP_OOC macro.
+
+Added -a option to getinfo for easy addition of header lines.
+
+Fixed issue with multiple records on picture output in rcontrib (and rfluxmtx).
+Credit to Sarith Subramaniam for pointing out the problem.
+
+Made mkillum more tolerant of non-planar polygons in its sampling routines.
+
+Added "-recover" option to genBSDF to pick up where it left off.
+
+Fixed genBSDF issue that was created incorrect normalization of
+Klems output.  Thanks to David G-M and Christian Knoflach for
+discovering the error.  Also improved sampling of indirect irradiance
+that showed some slight bias due to poor sample collision avoidance.
+
+Fixed long-standing issue with -aa 0 neglecting textures in calculating
+surface shading.
+
+Fixed bug in ranimove introduced during photon map integration.
+
+Added check for steep sections of BSDF in pabopto2bsdf, creating narrower
+peakes in those places and mitigating some normalization issues.
+
+Added view360stereo.cal by Mark Stock to handle 360-degree over/under
+stereo views.
+
+Added MAX2SHADE macro to place limit on number of light sources
+to precheck for obstructions.  (Currently set to 200.)  This
+avoids excessive start-up times for scenes with many light sources.
+Thanks to Axel Jacobs for pointing out the problem.
+
+Added -v option to obj2mesh to print out mesh statistics.
+
+Rewrote bsdf2rad from ground up and made it a standard part of build.
+
+Fixed bug in orientation of Reinhart/Tregenza sample generator in rfluxmtx.
+
+Added ability to perform shadow-testing through unproxied BSDFs with strong
+through (direct-direct) component.
+
+Added {+|-}a options to genBSDF and bsdf2ttree for switching off reciprocity
+averaging.
+
+Added bias to see through BTDFs with a strong "through" component
+rather than scattering view rays.  This is in lieu of peak extraction,
+which looked to be too difficult from an implementation standpoint.
+
+Added bsdfview tool analogous to objview but for BSDF files (XML and SIR),
+which calls bsdf2rad then rad with a few useful default views.
