In Mediawiki How do you know which version you have? Then how do you upgrade to the latest version?

Answer 1

The easiest way to get the version number you are running is to check the RELEASE-NOTES document that came with your code (open it with any text editor).

The easiest way to get info on how to upgrade is to read the UPGRADE document that came with your code

If you don't have the RELEASE-NOTES document available, you can add the PHP code

"; ?>

someplace in your wiki's index.php page, and it will echo out the current version.
