+Subject:  ANNOUNCE: mdadm 3.2.4 - A tool for managing Soft RAID under Linux
+
+I am pleased to announce the availability of
+   mdadm version 3.2.4
+
+It is available at the usual places, now including github:
+   countrycode=xx.
+   http://www.${countrycode}kernel.org/pub/linux/utils/raid/mdadm/
+and via git at
+   git://github.com/neilbrown/mdadm
+   git://neil.brown.name/mdadm
+   http://neil.brown.name/git/mdadm
+
+This release is largely a bugfix release for the 3.2 series with many
+minor fixes with little or no impact.
+
+"--oneline" log of changes is below.  Some notable ones are:
+
+ - --offroot argument to improve interactions between mdmon and initrd
+ - --prefer argument to select which /dev names to display in some
+   circumstances.
+ - relax restructions on when "--add" will be allowed
+ - Fix bug with adding write-intent-bitmap to active array
+ - Now defaults to "/run/mdadm" for storing run-time files.
+
+Upgrading is encouraged.
+
+The next mdadm release is expected to be 3.3 with a number of new
+features.
