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.
