Release Notes: Lots of bugs were fixed. Improvements were made for booting from Intel IMSM metadata arrays. The default metadata version was changed to 1.2.
Release Notes: This significant release included improved reshape support, improved DDF support, hot replace, and bad-block-log functionality. Array names can now have names (md_home) instead of just numbers (md0). There were several minor new features and many bugfixes.
Release Notes: This stability release adds a number of bugfixes to 3.2.5. There are no real standout fixes, just lots of little bits and pieces.
Release Notes: This release fixes a serious regression that caused adding a device with "--add" to sometimes fail when it should not. This did not cause any risk to data. The "--layout=preserve" option for "--grow" was fixed.
Release Notes: This is largely a bugfix release for the 3.2 series with many minor fixes with little or no impact. Some notable inclusions are: an --offroot argument to improve interactions between mdmon and initrd; a --prefer argument to select which /dev names to display in some circumstances; and relaxed restrictions on when "--add" will be allowed. A bug with adding write-intent-bitmap to an active array has been fixed. The default has been changed to use "/run/mdadm" for storing run-time files.
Release Notes: Stability fixes were made. IMSM metadata reshape (OnLine Capacity Expansion) is no longer experimental. The "--grow --size" options can have "--assume-clean" to suppress extra resync. RAID0 chunk size no longer has to be a power of 2.
