   6 It is available at the usual places:

  13 This is a bugfix release over 3.1, which was withdrawn due to serious
  14 bugs.  So it might be best to ignore 3.1 and say that this is a significant
  15 feature release over 3.0.x
  16
  17 Significant changes are:
  18   - RAID level conversion between RAID1, RAID5, and RAID6 are
  19     possible were the kernel supports it (2.6.32 at least)
  20   - online chunksize and layout changing for RAID5 and RAID6
  21     where the kernel supports it.
  22   - reduce the number of devices in a RAID4/5/6 array.
  23
  24   - The default metadata is not v1.1.  This metadata is stored at the
  25     start of the device so is safer in many ways but could interfere with
  26     boot loaded.  The old default (0.90) is still available and fully
  27     supported.
  28
  29   - The default chunksize is now 512K rather than 64K.  This seems more
  30     appropriate for modern devices.
  31
  32   - The default bitmap chunksize for internal bitmaps is now at least
  33     64Meg as fine grained bitmaps tend to impact performance more for
  34     little extra gain.
  35
  36 This release is believed to be stable and you should feel free to
  37 upgrade to 3.1.1.
