+Subject: ANNOUNCE: mdadm 3.1.1 - A tool for managing Soft RAID under Linux
+
+I am pleased to announce the availability of
+ mdadm version 3.1.1
+
+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+This is a bugfix release over 3.1, which was withdrawn due to serious
+bugs. So it might be best to ignore 3.1 and say that this is a significant
+feature release over 3.0.x
+
+Significant changes are:
+ - RAID level conversion between RAID1, RAID5, and RAID6 are
+ possible were the kernel supports it (2.6.32 at least)
+ - online chunksize and layout changing for RAID5 and RAID6
+ where the kernel supports it.
+ - reduce the number of devices in a RAID4/5/6 array.
+
+ - The default metadata is not v1.1. This metadata is stored at the
+ start of the device so is safer in many ways but could interfere with
+ boot loaded. The old default (0.90) is still available and fully
+ supported.
+
+ - The default chunksize is now 512K rather than 64K. This seems more
+ appropriate for modern devices.
+
+ - The default bitmap chunksize for internal bitmaps is now at least
+ 64Meg as fine grained bitmaps tend to impact performance more for
+ little extra gain.
+
+This release is believed to be stable and you should feel free to
+upgrade to 3.1.1.

Please see git logs for detailed change log.
This file just contains highlight.
+Changes Prior to release 3.1.1
+ - Multiple fixes for new --grow levels including fixes for
+ serious data corruption problems.
+ - Change default metadata to v1.1
+ - Change default chunk size to 512K
+ - Change default bitmap chunk size to 64Meg
+ - When --re-add is used, don't fall back to
+ --add if --re-add fails as this can destroy data.
+
Changes Prior to release 3.1
- Support --grow to change the layout of RAID4/5/6
