Sorry about the capital letters, but I guess a problem of this caliber
deserves some attention.

Ferenc will commit a patch today, that may cause data loss, if you
upgrade to it without looking over both your shoulders twice.  Please
read the whole thread named:
[PATCH] remove support for virtual blocks

After you understand the problem, please decide for yourself.  If you
are absolutely sure that you never used virtual block aggregation for
any of your JFFS2 filesystems, then you can safely upgrade.  This
should be true for the vast majority, but you should check it anyway.

If you are not sure, please make a backup of all your data using the
old code.  Then create a new filesystem using the new code and restore
your data.

I will send another mail once the patch is integrated in cvs.

Jörn
