+- Added -messageid switch to send(1) and post(8). This allows
+ selection of the style to use for generated Message-ID and
+ Content-ID header fields. The default localname style is
+ pid.time@localname, where time is in seconds, and matches previous
+ behavior. The random style replaces the localname with some
+ (pseudo)random bytes and uses microsecond-resolution time.
+- Added -clobber switch to mhstore(1) to control overwriting of
+ existing files.
+- Added -noall/-all switches to sortm(1). sortm -noall requires
+ a messages argument.
+- $PAGER overrides the compiled-in default pager command.
+- Added etc/scan.highlighted format file, as an example of how to
+ highlight/colorize the output of scan(1).
+- inc(1) now supports a -port switch to specify the port used by the
+ POP server.
+- pick(1) now decodes MIME-encoded header fields before searching.
