What
While copying plugin files during install or relink, an entry listed as a directory that turns out to be a symlink or a Windows junction now aborts the copy with an explicit error, rather than being followed. This catches links planted in a plugin tree or swapped in while the copy is running.
Details
applies to every plugin source tree copy
the message states that plugin trees must hold plain directories
Evidence
it is no longer a directory as listed — a link or Windows junction stands there (planted, or swapped during the copy). Plugin trees must hold plain directories.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
