What it means for your work
Workflows and integrations pinned to these models need to move before 16 November. Organisations that turned off default model enablement have to enable the replacements themselves.
Our read on the items that move something. The reporting is everyone's; this part is ours.

If your requirement is loose, a fresh install now pulls the 2.x library and the reference servers will not start on it. Pin explicitly before the next deploy.
Six days from spec publication to GA across every Copilot surface, with the two largest rival vendors co-maintaining, is the point at which packaging skills and MCP servers separately per client stops being worth the effort.
If you have wanted your own data in front of a chat assistant without building an app, this is the current shortest real path, written down by someone who did it.
