What

A plugin manifest is now rejected with a validation error if its name is empty or contains @, :, whitespace, a path separator, or an invisible or control character. Naming a plugin after its own directory produces a specific hint.

Details
  • A manifest version containing unprintable characters is treated as if absent, with a warning rather than a hard failure.
Evidence

must be non-empty and must not contain "@", ":", whitespace, path separators, or invisible/control characters

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