No changes are required unless you wish to change from using another
character set to using UTF-8.  This is not done automatically, because the
effects are too far-reaching.

A migration tool was developed, but it was not ready in time to be used for
the release (utf8-migration-tool).

This is a risky procedure for an average user to attempt, and in most cases
it is unnecessary.  I do not recommend that users perform this conversion as
a matter of course when upgrading to Hoary.  The existing configuration will
continue to work.

You added this to the WartyUpgradeNotes page in the wiki, which is not where
it belongs.  I moved it to HoaryUpgradeNotes.
