+Changes Prior to 2.6.2 release
+ - --fail detached and --remove faulty can be used to fail and
+ remove devices that are no longer physically present.
+ - --export option for --detail or present information in a format
+ that can be processed by udev.
+ - fix internal bitmap allocation problems with v1.1, v1.2 metadata.
+ - --help now goes to stdout so you can direct it to a pager.
+ - Various manpage updates.
+ - Make "--grow --add" for linear arrays really work.
+ - --auto-detect to trigger in-kernel autodetect.
+ - Make return code for "--detail --test" more reliable. Missing
+ devices as well as failed devices cause an error.
+
+Changes Prior to 2.6.1 release
+ - --monitor was producing some meaningless warnings due to a bug.
+ - Fix some compiler warnings.
+ - Fully support --grow for raid6. If a reshape crashed during the
+ critical period, mdadm wouldn't restore the Q information
+ properly.
+ - Update documentation for --grow.
+
+Changes Prior to 2.6 release
- Fixed UUID printing in "--detail --brief" for version1 metadata.
- --update=resync did exactly the wrong thing for version1 metadata.
It caused a resync to not happen, rather than to happen.
missing devices (which is needed else if won't assemble.
Without this fix it would only assemble if one or zero
missing devices.
+ - Support --update=devicesize for cases where the underlying device
+ can change size.
+ - Default to --auto=yes so the array devices with 'standard' names
+ get created automatically, as this is almost always what is wanted.
+ - Give useful message if raid4/5/6 cannot be started because it is
+ not clean and is also degraded.
+ - Increase raid456 stripe cache size if needed to --grow the array.
+ The setting used unfortunately requires intimate knowledge of the
+ kernel, and it not reset when the reshape finishes.
+ - Change 'Device Size' to 'Used Dev Size' because it only shows how
+ much of each device is actually used, not how big they are.
+ - --wait or -W will wait for resync activity to finish on the given
+ devices.
+ - Fix some problems with --update=uuid and add a test.
+ - If two drives in a raid5 disappear at the same time, then "-Af"
+ will add them both in rather than just one and forcing the array
+ to 'clean'. This is slightly safer in some cases.
+ - Check device is large enough before hot-add: this improves quality
+ of error message.
+ - Don't hold md device open for so long in --monitor mode - map_dev
+ can be slow and interferes with trying to stop the array.
+ - Support --uuid= with --create to choose your own UUID.
+ - New major more "--incremental" for incremental assemble of arrays,
+ intended for use with udev.
