+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}
+and via git at
+ git://
+This is a bugfix release over 3.1, which was withdrawn due to serious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.
