The new section says what yarilo#2351 does: the four subscribed special-use folders for the INBOX-owning namespace without a mailboxes block and for a server with no namespaces, shown as the block they stand for; a block of one's own replaces the whole set, {} makes none, other namespaces and virtual views get nothing, and a deleted default folder comes back on the next list or open. The auto card carries the 2.4.5 change note and points at the section. Check run green (22 s).
