o Major features:
- Allow Tor controllers like Vidalia to obtain the microdescriptor
for a relay by identity digest or nickname. Previously,
microdescriptors were only available by their own digests, so a
controller would have to ask for and parse the whole
microdescriptor consensus in order to look up a single relay's
microdesc. Fixes bug 3832; bugfix on 0.2.3.1-alpha.
