+=================================
+Version 5.1
+
+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.
