BSA apparently released a new set of requirements for the Canoeing Merit Badge about a month ago. The new requirements were posted on scouting.org, and are now also posted on usscouts.org, and meritbadge.org. I've also updated and uploaded a new version of the workbook to both usscouts.org and meritbadge.org.
In general, the changes involve more renumbering than content changes.
Other than wording changes, here's how the old and new requirements compare:
Old requirements 1, 2, and 4 were replaced by new requirements 1a - 1c.
Old requirement 3 became requirement 2.
Old requirements 5a-5k became requirements 3a-3c, 4a-4b, 5a-5b, 6, and 7a-7c.
Old requirements 6a-6h became requirements 8a-8d and 9a-9d.
Old requirement 7a-g became requirements 10a-g, and a new requirement 10h was added.
Old requirement 8 became requirement 11.
Old requirement 9 became requirement 12, the introduction was revised, and old requirement 9e was dropped.
Old requirement 10a was replaced with requirements 13a and 13b, and 10b-10f became 13c-13g.
