Hi @malthert, welcome to WordPress Trac! Thanks for the report.

I could not reproduce the issue so far.

1. Are you using a database drop-in (a wp-content/db.php file) or any caching plugins?
2. Does the notice still persist after the upgrade, or only appears during the upgrade?
3. Has the blogmeta table been created in the database?

[malthert]

1) no
2) no, only happened once during the update
3) no it's not there (I am on a simple WP install, no multi-site)

@malthert Just wanted to confirm that closing this ticket was intentional. If possible, sharing the source of the problem could help others that run into a similar issue.

Thanks, yes it was intentional. I never encountered the issue again. Since it's been quite a few versions in the meantime, I assume the issue has been fixed somehow.
