+Subject:  ANNOUNCE: mdadm 3.1.2 - A tool for managing Soft RAID under Linux
+
+I am pleased to announce the availability of
+   mdadm version 3.1.2
+
+It is available at the usual places:
+   countrycode=xx.
+   http://www.${countrycode}kernel.org/pub/linux/utils/raid/mdadm/
+and via git at
+   git://neil.brown.name/mdadm
+   http://neil.brown.name/git?p=mdadm
+
+This is a bugfix/stability release over 3.1.1.
+
+Significant changes are:
+  - The default metadata has change again (sorry about that).
+    It is now v1.2 and will hopefully stay that way.  It turned
+    out there with boot-block issues with v1.1 which make it 
+    unsuitable for a default, though in many cases it is still
+    suitable to use.
+  - Stopping a container is not permitted when members are still
+    active
+  - Add 'homehost' to the valid words for the "AUTO" config file
+    line.  When followed by "-all", this causes mdadm to
+    auto-assemble any array belonging to this host, but not
+    auto-assemble anything else.
+  - Fix some bugs with "--grow --chunksize=" for changing chunksize.
+  - VAR_RUN can be easily changed at compile time just like ALT_RUN.
+    This gives distros more flexability in how to manage the
+    pid and sock files that mdmon needs.
+  - Various mdmon fixes
+  - Alway make bitmap 4K-aligned if at all possible.
+  - If mdadm.conf lists arrays which have inter-dependencies,
+    the previously had to be listed in the "right" order.  Now
+    any order should work.
+  - Fix --force assembly of v1.x arrays which are in the process
+    of recovering.
+  - Add section on 'scrubbing' to 'md' man page.
+  - Various command-line-option parsing improvements.
+  - ... and lots of other bug fixes.
+
+
+This release is believed to be stable and you should feel free to
+upgrade to 3.1.2
