1 o Minor bugfixes (directory authority):
2 - When a directory authority rejects a descriptor or extrainfo with
3 a given digest, mark that digest as undownloadable, so that we
4 do not attempt to download it again over and over. We previously
5 tried to avoid downloading such descriptors by other means, but
6 we didn't notice if we accidentally downloaded one anyway. This
7 behavior became problematic in 0.2.7.2-alpha, when authorities
8 began pinning Ed25519 keys. Fixes ticket
9 22349; bugfix on 0.2.1.19-alpha.
