Thanks for sharing that. Information on doing backups has been changed since years ago, and an effort has been made to update those guidelines. If there was any particular help file that you saw that is out of date, please share the URL and we will investigate it, as we share your desire to have current documentation. Thanks for sharing.

I didn't have a particular help article in mind. I've just wanted this feature for a while.

There is an extensive history for all articles. These are living documents, so most have a history that goes back many years and many versions. They do not suddenly become obsolete or lose value simply because a new version is released with a slight change to the user interface. Although with some things major updates are needed to make them accurate post change, you will never see a whole new set of documents dated after a new release.

To take this one as an example. https://support.mozilla.org/en-US/kb/thunderbird-export The "Show History" link on the page shows https://support.mozilla.org/en-US/kb/thunderbird-export/history

As a much older article, https://support.mozilla.org/en-US/kb/keyboard-shortcuts-thunderbird shows versions back to 2014 when the Thunderbird support articles were migrated to this website. https://support.mozilla.org/en-US/kb/keyboard-shortcuts-thunderbird/history

I can't believe I didn't see the Show History link. I didn't realize this site is running on MediaWiki (or similar wiki software).
