+10. RAIDframe parity map
+------------------------
+
+Jed Davis successfully completed a Summer of Code project to implement
+parity map zones for RAIDframe. Parity mapping drastically reduces
+the amount of time spent rewriting parity after an unclean shutdown by
+keeping better track of which regions might have had outstanding
+writes. Enabled by default; can be disabled on a per-set basis, or
+tuned, with the new raidctl(8) commands.
+
+Merged in 5.99.22 sources, and will be in 6.0. A separate set of
+patches is available for NetBSD-5.

+-------------------------------------------
+
+mDNSResponder (also known as mdnsd on some systems) is a daemon invoked
+at boot time to implement Multicast DNS and DNS Service Discovery. On Mac
+OS X 10.6 (Snow Leopard), mDNSResponder is also the system-wide Unicast
+DNS Resolver. Ty Sarna added support for mdnsd to NetBSD-current, and it
+will appear in NetBSD 6.0.
