Tor 0.1.1.21 fixes minor stability and protocol correctness problems,
mainly for Tor servers. We've also upgraded the Windows bundle with
Vidalia 0.0.5, and we're linking to a new OS X bundle with Vidalia 0.0.5
(finally a better interface for Mac users!). Lastly, we've added support
for SUSE-style RPM packages.
We're still tracking down some reported bugs in Tor server reachability
testing.

Changes in version 0.1.1.21 - 2006-06-10
o Crash and assert fixes from 0.1.1.20:
- Fix a rare crash on Tor servers that have enabled hibernation.
- Fix a seg fault on startup for Tor networks that use only one
directory authority.
- Fix an assert from a race condition that occurs on Tor servers
while exiting, where various threads are trying to log that they're
exiting, and delete the logs, at the same time.
- Make our unit tests pass again on certain obscure platforms.
o Other fixes:
- Add support for building SUSE RPM packages.
- Speed up initial bootstrapping for clients: if we are making our
first ever connection to any entry guard, then don't mark it down
right after that.
- When only one Tor server in the network is labelled as a guard,
and we've already picked him, we would cycle endlessly picking him
again, being unhappy about it, etc. Now we specifically exclude
current guards when picking a new guard.
- Servers send create cells more reliably after the TLS connection
is established: we were sometimes forgetting to send half of them
when we had more than one pending.
- If we get a create cell that asks us to extend somewhere, but the
Tor server there doesn't match the expected digest, we now send
a destroy cell back, rather than silently doing nothing.
- Make options->RedirectExit work again.
- Make cookie authentication for the controller work again.
- Stop being picky about unusual characters in the arguments to
mapaddress. It's none of our business.
- Add a new config option "TestVia" that lets you specify preferred
middle hops to use for test circuits. Perhaps this will let me
debug the reachability problems better.
o Log / documentation fixes:
- If we're a server and some peer has a broken TLS certificate, don't
log about it unless ProtocolWarnings is set, i.e., we want to hear
about protocol violations by others.
- Fix spelling of VirtualAddrNetwork in man page.
- Add a better explanation at the top of the autogenerated torrc file
about what happened to our old torrc.
