-  o Major bugfixes (bootstrap):
-    - Check if bootstrap consensus downloads are still needed
-      when the linked connection attaches. This prevents tor
-      making unnecessary begindir-style connections, which are
-      the only directory connections tor clients make since
-      the fix for 18483 was merged.
-    - Fix some edge cases where consensus download connections
-      may not have been closed, even though they were not needed.
-      Related to fix  18809.
-    - Make relays retry consensus downloads the correct number of
-      times, rather than the more aggressive client retry count.
-      Fixes part of ticket 18809.
-    - Stop downloading consensuses when we have a consensus,
-      even if we don't have all the certificates for it yet.
-      Fixes bug 18809; bugfix on 0.2.8.1-alpha.
