-  o Minor features
-    - Servers now save observed maximum bandwidth throughput rates
-      to their state file (along with total usage, which was already
-      saved) so that they can determine their correct estimated
-      bandwidth on restart.  Resolves bug 1863, where Tor servers
-      would reset their estimated bandwidth to 0 after restarting.

-  o Minor bugfixes
-    - Fix a bug in banwidth history state parsing that could have been
-      triggered if a future version of Tor ever changed the timing
-      granularity at which bandwidth history is measured.  Bugfix on

-  o Major features and bugfixes (node selection)
-
-    - Revise and unify the meaning of the ExitNodes, EntryNodes,
-      ExcludeEntryNodes, ExcludeExitNodes, ExcludeNodes, and
-      StrictNodes options.  Previously, we had been ambiguous in
-      describing what counted as an "exit" node, and what operations
-      exactly "StrictNodes 0" would permit.  This created confusion
-      when people saw nodes built through unexpected circuits, and
-      made it hard to tell real bugs from surprises.  We now stipulate
-      that the intended behavior is:
-
-	. "Exit", in the context of ExitNodes and ExcludeExitNodes,
-	   means a node that delivers user traffic outside the Tor
-	   network.
-	. "Entry", in the context of EntryNodes and ExcludeEntryNodes,
-	  means a node used as the first hop of a multihop circuit:
-	  it doesn't include direct connections to directory servers.
-	. "ExcludeNodes" applies to all nodes.
-	. "StrictNodes" changes the behavior of ExcludeNodes only.
-	  When StrictNodes is set, Tor should avoid all nodes listed
-	  in ExcludeNodes, even when it will make user requests
-	  fail.  When StrictNodes is *not* set, then Tor should
-	  follow ExcludeNodes whenever it can, except when it must
-	  use an excluded node to perform self-tests, connect to a
-	  hidden service, provide a hidden service, fulfill a .exit
-	  request, upload directory information, or fetch directory
-	  information.
-
-      Collectively, the changes to implement the behavior are a fix for
-      bug 1090.
-
-    - ExcludeNodes now takes precedence over EntryNodes and ExitNodes:
-      if a node is listed in both, it's treated as excluded.
-
-    - ExcludeNodes now applies to directory nodes: as a preference if
-      StrictNodes is 0, or an absolute requirement if StrictNodes is 1.
-      (Don't exclude all the directory authorities and set StrictNodes
-      to 1 unless you really want your Tor to break.)
-
-    - ExcludeNodes and ExcludeExitNodes now override exit enclaving.
-
-    - ExcludeExitNodes now overrides .exit requests.
-
-    - We don't use bridges from ExcludeNodes.
-
-    - When StrictNodes is 1:
-       . We now apply ExcludeNodes to hidden service introduction points
-         and to rendezvous points selected by hidden service users.
-         This can make your hidden service less reliable: use it with
-         caution!
-       . If we have used ExcludeNodes on ourself, do not try self-tests.
-       . If we have excluded all the directory authorities, we will
-         not even try to upload our descriptor if we're a server.
-       . Do not honor .exit requests to an excluded node.
-
-    - Remove a misfeature that caused us to ignore the Fast/Stable flags
-      if ExitNodes was set.  Bugfix on 0.2.2.7-alpha.
-
-    - When the set of permitted nodes changes, we now remove any
-      mappings introduced via TrackExitHosts to now-excluded nodes.
-      Bugfix on 0.1.0.1-rc.
-
-    - We never cannibalize a circuit that had excluded nodes on it,
-      even if StrictNodes is 0.  Bugfix on 0.1.0.1-rc.
-
-    - Improve log messages related to excluded nodes.
-
-    - Revert a change where we would be laxer about attaching streams to
-      circuits than when building the circuits.  This was meant to
-      prevent a set of bugs where streams were never attachable, but our
-      improved code here should make this unnecessary.  Bugfix on
-      0.2.2.7-alpha.

-  o Minor features
-    - Make it simpler to specify "All log domains except for A and B".
-      Previously you needed to say "[*,~A,~B]".  Now you can just say
-      "[~A,~B]".
-    - Add a LogMessageDomains option to include the domains of log messages
-      along with the messages.  Without this, there's no way to use
-      log domains without reading the source or doing a lot of guessing
-
-  o Documentation
-    - Add documentation for configuring logging at different severities in
-      different log domains.  We've had this feature since 0.2.1.1-alpha, but
-      for some reason it never made it into the manpage.  Fixes bug 2215.
