  • 2:29 "it's now also possible to actually use agents to try to generate" - Notes that agents can be used to generate page scripts.

Documented features match

Docs checked on 2026-10-02: the match is against Microsoft's what's new pages for the wave as they were on that date. Microsoft keeps filling the documentation, so "no documented item" can go stale. The wider product documentation on learn.microsoft.com was searched for this feature on the same date; the feature's data lists an article when one was found.
