 Taoning Wang added genssky tool for generating spectral sky
 descriptions.
+
+Taoning added gensdaymtx utility based on gendaymtx, and
+added epw2wea -a option to include required information.
+
+Fixed bug introduced in Auguest 2022 (5.4 release) in distant
+light source sampling, which caused aiming failures.  (Thanks
+to Mike DiPompeo of LightStanza for reporting the issue.)
+
+Added rxpict rendering tool based on C++ RpictSimulManager class.
+Multi-processing and spectral output are supported.
+
+Added crude ability to read and convert spectra to RGB in ximage,
+ra_bmp, and ra_rgbe programs.  Also updated fast tone-mapping
+library to handle spectral HSR inputs at the same time.  HSR
+input handling was added in a similar fashion to pcond and pvalue.
+
+Wrote rxpiece tool that will render pictures using tiling and
+can handle different output formats and hyperspectral pictures.
+Only runs on a single machine, however -- now NFS locking on
+shared volumes.  Mainly a demonstration tool for RpictSimulManager
+C++ class, but may have its uses.
+
+Fixed a bug in BSDF sampling of sources pointed out by
+David Geisler-Moroder, which tended to overestimate specular
+contributions for some BSDFs.
+
+Added handling of hyperspectral pictures to pextrem, though
+results are still reported in RGB.
