 Changes Prior to this release
+    -   Avoid segfault when parsing /proc/mdstat with auto-read-only
+       arrays.
+    -   Fix problem with failing to add devices to v.large (>4TB) arrays,
+       cause by problems with device-size overflow.
+    -   For v0.90 superblocks, print the 'Events' count as a real count,
+       not 2 numbers separated by a dot.
+    -   Updates some URLs in the man page.
+    -   Allow creation of a RAID6 with exactly one missing device.
+
+Changes Prior to 2.6.4 release
+    -   Make "--create --auto=mdp" work for non-standard device names.
+    -   Fix restarting of a 'reshape' if it was stopped in the middle.
+    -   Fix a segfault when using v1 superblock.
+    -   Make --write-mostly effective when re-adding a device to an array.
+    -   Various minor fixes
+
+Changes Prior to 2.6.3 release
+    -   allow --write-behind to be set for --grow.
+    -   When adding new disk to an array, don't reserve so much bitmap
+        space that the disk cannot store the required data. (Needed when
+       1.x array was created with older mdadm).
+    -   When adding a drive that was a little too small, we did not get
+       the correct error message.
+    -   Make sure that if --assemble find an array in the critical region
+       of a reshape, and cannot find the critical data to restart the
+       reshape, it gives an error message.
+    -   Fix segfault with '--detail --export' and non-persistent
+        superblocks.
+    -   Various manpage updates.
+    -   Improved 'raid4' support (--assemble, --monitor)
+    -   Option parsing fixes w.r.t -a
+    -   Interpret "--assemble --metadata=1" to allow any version 1.x
+       metadata, and be more specific in the "metadata=" message printed
+       with --examine --brief
+    -   Fix spare migration in --monitor.
+
+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.
