 Changed dctimestep so that output matrices (-n > 1) are preceded by a
 header, and added support for float and double output formats with -o[fd].
+
+Introduced eplus_adduvf program to compute user view factors for EnergyPlus.
+
+Changed image-plane sampling in rpict to use Hilbert curve, which gives
+less of a brushed/striped appearance to output pixels with -u- (default).
+
+Added ltview and ltpict Perl scripts contributed by Axel Jacobs, inspired
+by Rob Guglielmetti.
+
+Added header variables for NROWS, NCOLS and NCOMP to help standardize
+matrix files.  This functionality has been incorporated into
+rcollate, gendaymtx, and dctimestep.
+
+Created rmtxop utility to operate on multi-component matrices.  This
+facilitates some daylight matrix calculations, and provides a general
+tool for manipulating matrix data.
+
+****** COMPATIBILITY CHANGE ********
+Introduced new Hessian-based error control in irradiance caching (ambient)
+calculation.  Since the format of the stored ambient values is different,
+the old files will be rejected with an error message and must be removed.
+The programs may be compiled with the -DOLDAMB option if this is a problem.
+
+Added -p option to rcontrib to set function file parameters on a per-modifier
+basis to simplify bin evaluation.
+
+Created rfluxmtx program to compute flux transfer matrices from a sender
+surface to one or more receiver surfaces.  (Renamed the file klems_int.cal
+to klems_full.cal in the process.)
