What

The small file kept next to each synced plugin now stores the marketplace name and an installation preference alongside the plugin id. An invalid marketplace name is reported through telemetry, and an unchanged sidecar is left in place rather than rewritten.

Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
