+Changes Prior to this 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.
+    -   Allow --assemble --force to mark a raid6 clean when it has two
+       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.
+
+Changes Prior to 2.5.6 release
+    -   Fix bug which meant "bitmap=xxx" in mdadm.conf was not handled
+       properly.
+    -  Documentation updates.
+    -   Fix bug that caused infinite loop when doing auto-assembly,
+       in certain cases where arrays couldn't be assembled.
+
+Changes Prior to 2.5.5 release
+    -   Don't #include linux/blkpg.h as that isn't safe.  Just
+       include the content literally.
+    -   Reduce maximum bitmap usage when working with bitmap files,
+       so that a only single-page allocations are made, even on
+       64bit hosts with 4K pages.
+    -   Close stray fd in mdassemble so that it can assemble stacked
+       devices
+    -   If mdassemble finds an array already assembled, it marks it
+        read-write.
+    -   Remove error in md_open if array is already active.  This isn't
+       needed and gets in the ways if an array was created e.g. in
+       initramfs, but device doesn't yet exist in /dev.
+    -   When --assemble --scan is run, if all arrays that could be found
+       have already been started, don't report an error.
+    -   Fix a couple of bugs related to raid10 and the new 'offset' layout.
+    -   Improve error message when a wrong '--update' option is given.
+
 Changes Prior to 2.5.4 release
     -   When creating devices in /dev/md/ create matching symlinks
        from /dev.  e.g. /dev/md0 -> /dev/md/0.
