Do you have documentation for the final change being on October 24th? The
database has the change occurring on September 3rd 2017. If there's
appropriate documentation showing that it actually changed on October 24th,
it would be good to update the database accordingly.

But other than the precise date, what you've described is what the rules
show as well. The 2017 part of the rules that Arthur Olsen included before
means that those rules terminate in 2017.

abbreviation CAT.

See https://nodatime.org/tzvalidate/generate?zone=Africa/Windhoek as an
example of the transitions, noting that the final line is:

2017-09-03 01:00:00Z +02:00:00 standard CAT

Because the time zone database covers the past as well as the future, and
Africa/Windhoek *used* to alternate between CAT and WAT.

Which specific other rule and format? It's not clear to me what you mean,
but I don't believe there's any problem here.
