o Major bugfixes:
- Don't launch a useless circuit after failing to use one of a
hidden service's introduction points. Previously, we would
launch a new introduction circuit, but not set the hidden
service which that circuit was intended to connect to, so it
would never actually be used. A different piece of code would
then create a new introduction circuit correctly, so this bug
was harmless until it caused an assertion in the client-side
part of the #3825 fix to fail. Bug reported by katmagic and
found by Sebastian Hahn. Bugfix on 0.2.1.13-alpha; fixes bug
4212.
