A table structure change will generate errors on your site if you do
not first drop the table.
If you run r1116 before dropping the table, you must roll back your
database version in your options table. If you need help with this,
please email the list or visit the #habari IRC channel on freenode
where someone can assist you.
This issue should not affect any sites running code from a zip file
distribution, only sites updating their code directly from the
in-development code repository. If this message seems like jibberish
to you and your site still runs properly, you have nothing to worry
about.
Sorry for the inconvenience,
Owen
