+1.2.3 (<date>)
+* Added variants of dirac_trace() and color_trace() that take the trace over
+ more than one representation label by specifying a set or list of labels.
+* diracgamma::contract_with() uses Chisholm identities in 4 dimensions to
+ produce more compact results.
+* The --enable-html-doc and --enable-ps-doc configure options are gone.
+ Documentation in HTML, DVI, PostScript, and PDF formats is now built with
+ "make html", "make dvi", "make ps", and "make pdf", respectively. The only
+ documentation that gets built by default are the tutorial in .info format
+ and the manpages.
