+ - When creating a bitmap file, choose a chunksize to limit number
+ of bitmap chunks to 2 million. More than this can cause kmalloc
+ failure.
+ - New 'CREATE' line in mdadm.conf for defaults such as owner, group,
+ mode and auto-flag
+ - --detail checks if array has been started or not and includes that
+ in report.
+ - When using --update=uuid on an array with a bitmap, update the
+ bitmap's uuid too.
+ - Add a copy of /proc/mdstat to the mail message sent by mdadm
+ --monitor.
+ - New flag --no-degraded to avoid starting arrays if there are
+ fewer devices available than last time the array was started.
+ This is only needed with --scan, as with --scan, that behaviour
+ is the default.
+ - Support for 'homehost' concept. This is a fairly major update.
+ It includes a configfile option and a command line option for
+ specifying a homehost, records that host in the superblock,
+ and reports the homehost where possible.
+ - Support for Auto Assembly. "mdadm -As" will, if provided with
+ the name of a homehost, try to assemble all arrays it can find
+ that were created for that homehost. See man pages for more details.
