  14 This release is largely a bugfix release for the 3.2 series with many
  15 minor fixes with little or no impact.
  16
  17 "--oneline" log of changes is below.  Some notable ones are:
  18
  19  - --offroot argument to improve interactions between mdmon and initrd
  20  - --prefer argument to select which /dev names to display in some
  21    circumstances.
  22  - relax restructions on when "--add" will be allowed
  23  - Fix bug with adding write-intent-bitmap to active array
  24  - Now defaults to "/run/mdadm" for storing run-time files.
  25
  26 Upgrading is encouraged.
  27
  28 The next mdadm release is expected to be 3.3 with a number of new
  29 features.
