Material for MkDocs is in maintenance mode. Now what?
If your documentation runs on Material for MkDocs, nothing broke when the project entered maintenance mode, and nothing will break on the day support ends. What changes is who carries the risk. Every Python upgrade, dependency advisory and browser change after that date lands on your team, with no upstream fix coming. That makes this a planning decision, not an emergency, and the right time to make it is while the maintainers are still shipping security fixes.
