+Changes Prior to 1.6.0 release
+    -  Device name given in -Eb is determined by examining /dev rather
+       than assuming /dev/md%d
+    -   Fix bug in --monitor where an array could be held open an so
+       could not be stopped without killing mdadm.
+    -   Add --grow mode.  Currently only --size and --raid-disks can be
+       changed. Both require kernel support which, at the time of
+       writing, is not in a release kernel yet.
+    -   Don't print out "errors" or "no-errors" in -D and -E, as the bit
+       is never set or used.
+    -   Use md event notification in 2.6.??? to make --monitor mode
+        respond instantly to events.
+    -   Add --auto= option and auto= configfile entry to tell mdadm to
+       create device files as needed.  This is particularly useful
+       with partitioned arrays where the major device number can change.
+    -   When generating --brief listing, if the standard name doesn't
+        exist, search /dev for one rather than using a temp name.
+    -   Allow --build to build raid1 and multipath arrays.
+    -   Add "--assume-clean" for Create and Build, particularly for raid1
+       Note: this is dangerous. Only use it if you are certain.
+    -   Fix bug so that Rebuild status monitoring works again.
+    -   Add "degraded" and "recovering" options to the "Status:"
+       entry for --detail
+
+Changes Prior to 1.5.0 release
+    -   new commands "mdassemble" which is a stripped-down equivalent of
+       "mdadm -As", that can be compiled with dietlibc.
+       Thanks to Luca Berra <bluca@comedia.it>.
+       It can be using in an initramfs or initrd.
+    -   Fix compiling error with BLKGETSIZE64 and some signed/unsigned
+       comparison warnings.
+    -   Add Rebuild Status (% complete) to --detail output.
+    -   Support "--monitor --test" which will generate a test alert
+       for each array once, to test notification paths.
+    -   Generate RebuildFinished event when rebuild finishes.
+    -   Support for raid6 as found in 2.6.2 - thanks to  
+       H. Peter Anvin  <hpa@zytor.com>
+    -   Support partitioned md arrays with a different major number and
+       naming scheme (md_dX in /proc/mdstat, /dev/md/dXpY in /dev).
+       
+Changes Prior to 1.4.0 release
+    -   Document fact that creating a raid5 array really creates a
+        degraded array with a spare.   
+    -   Add "spares=" tag to config file and generate it wit --detail and
+        --examine
+    -   Add "SparesMissing" event when --monitor first sees an array and
+       it doesn't have the enough spare devices.
+    -   Add --update=summaries for --assemble to update summary
+        information in superblock, and correct other inconsistancies in
+       the superblock.
+    -   Add --test option to --detail to set a meaningful exit status.
+       
 Changes Prior to 1.3.0 release
     -   Make 'size' and unsigned long in Create to allow creation of
         larger arrays.

   the --help output, is not wholy correct.  After I get --follow
   working properly, I plan to revise the various documentation and/or
   the code to make sure the two match.
