There is no install\upgrade.php files & folders included in the 1.8.26 upgrade package.
Do we simply close the forum, backup files/database, replace all files within the changed_files_1826.zip and reopen the forum?
Nice and easy if so...

If there are no install directory, it means that the only changes are in files, not in database or templates.
Then, your process is ok (close, save, upload, open).

Take care this is only available if your previous version is just one point behind (so, you're actually using version 1.8.25)

All good and thank you for confirming that
