* Changes to the procedure for linking libguile with your programs
-* Changes to Scheme functions
+* Changes to Scheme functions and syntax
+
+** Guile now supports a new R4RS-compliant syntax for keywords. A
+token of the form #:NAME, where NAME has the same syntax as a Scheme
+symbol, is the external representation of the keyword named NAME.
+Keyword objects print using this syntax as well, so values containing
+keyword objects can be read back into Guile.
+
+Guile suports this read syntax, and uses this print syntax, regardless
+of the current setting of the `keyword' read option. The `keyword'
+read option only controls whether Guile recognizes the `:NAME' syntax,
+which is incompatible with R4RS. (R4RS says such token represent
+symbols.)
** Guile has regular expression support again. Guile 1.0 included
functions for matching regular expressions, based on the Rx library.
