MediaWiki 1.46 Support: Frequently Asked Questions

Is the MediaWiki 1.46 still supported?

Yes. The MediaWiki 1.46 is currently supported by MediaWiki, and third-party support is available as an alternative — issue management, vulnerability remediation, and compliance help independent of the vendor contract.
