+UPGRADING FROM 3.8.8 and earlier - Changes:
+
+Previous versions of RT used a password hashing scheme which was too
+easy to reverse, which could allow attackers with read access to the
+RT database to possibly compromise users' passwords. Even if RT does
+no password authentication itself, it may still store these weak
+password hashes -- using ExternalAuth does not guarantee that you are
+not vulnerable! To upgrade stored passwords to a stronger hash, run:
+
+ perl etc/upgrade/vulnerable-passwords
+
+
+We've proved that it's possible to delete set of records
+from Transactions table without losing functionality. To delete
+records run the following script:
+
+ perl -I /opt/rt3/local/lib -I /opt/rt3/lib etc/upgrade/shrink_transactions_table.pl
+
+If you chose not to run the shrink_cgm_table.pl script when you upgraded to 3.8,
+you should read more about it below and run it at this point.
