DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs.

What
Messages such as a plugin's command not having been run, command-sourced plugins being disabled, and the feature not being supported on Windows yet are now classified as policy failures rather than unknown ones, which changes how they are surfaced.
Evidence
Command-sourced plugins are disabled
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
