+Changes in version 0.2.2.26-beta - 2011-05-17
+  Tor 0.2.2.26-beta fixes a variety of potential privacy problems. It
+  also introduces a new "socksport auto" approach that should make it
+  easier to run multiple Tors on the same system, and does a lot of
+  cleanup to get us closer to a release candidate.
+
+  o Security/privacy fixes:
+    - Replace all potentially sensitive memory comparison operations
+      with versions whose runtime does not depend on the data being
+      compared. This will help resist a class of attacks where an
+      adversary can use variations in timing information to learn
+      sensitive data. Fix for one case of bug 3122. (Safe memcmp
+      implementation by Robert Ransom based partially on code by DJB.)
+    - When receiving a hidden service descriptor, check that it is for
+      the hidden service we wanted. Previously, Tor would store any
+      hidden service descriptors that a directory gave it, whether it
+      wanted them or not. This wouldn't have let an attacker impersonate
+      a hidden service, but it did let directories pre-seed a client
+      with descriptors that it didn't want. Bugfix on 0.0.6.
+    - On SIGHUP, do not clear out all TrackHostExits mappings, client
+      DNS cache entries, and virtual address mappings: that's what
+      NEWNYM is for. Fixes bug 1345; bugfix on 0.1.0.1-rc.
+
+  o Major features:
+    - The options SocksPort, ControlPort, and so on now all accept a
+      value "auto" that opens a socket on an OS-selected port. A
+      new ControlPortWriteToFile option tells Tor to write its
+      actual control port or ports to a chosen file. If the option
+      ControlPortFileGroupReadable is set, the file is created as
+      group-readable. Now users can run two Tor clients on the same
+      system without needing to manually mess with parameters. Resolves
+      part of ticket 3076.
+    - Set SO_REUSEADDR on all sockets, not just listeners. This should
+      help busy exit nodes avoid running out of useable ports just
+      because all the ports have been used in the near past. Resolves
+      issue 2850.
+
+  o Minor features:
+    - New "GETINFO net/listeners/(type)" controller command to return
+      a list of addresses and ports that are bound for listeners for a
+      given connection type. This is useful when the user has configured
+      "SocksPort auto" and the controller needs to know which port got
+      chosen. Resolves another part of ticket 3076.
+    - Add a new ControlSocketsGroupWritable configuration option: when
+      it is turned on, ControlSockets are group-writeable by the default
+      group of the current user. Patch by Jérémy Bobbio; implements
+      ticket 2972.
+    - Tor now refuses to create a ControlSocket in a directory that is
+      world-readable (or group-readable if ControlSocketsGroupWritable
+      is 0). This is necessary because some operating systems do not
+      enforce permissions on an AF_UNIX sockets. Permissions on the
+      directory holding the socket, however, seems to work everywhere.
+    - Rate-limit a warning about failures to download v2 networkstatus
+      documents. Resolves part of bug 1352.
+    - Backport code from 0.2.3.x that allows directory authorities to
+      clean their microdescriptor caches. Needed to resolve bug 2230.
+    - When an HTTPS proxy reports "403 Forbidden", we now explain
+      what it means rather than calling it an unexpected status code.
+      Closes bug 2503. Patch from Michael Yakubovich.
+    - Update to the May 1 2011 Maxmind GeoLite Country database.
+
+  o Minor bugfixes:
+    - Authorities now clean their microdesc cache periodically and when
+      reading from disk initially, not only when adding new descriptors.
+      This prevents a bug where we could lose microdescriptors. Bugfix
+      on 0.2.2.6-alpha. 2230
+    - Do not crash when our configuration file becomes unreadable, for
+      example due to a permissions change, between when we start up
+      and when a controller calls SAVECONF. Fixes bug 3135; bugfix
+      on 0.0.9pre6.
+    - Avoid a bug that would keep us from replacing a microdescriptor
+      cache on Windows. (We would try to replace the file while still
+      holding it open. That's fine on Unix, but Windows doesn't let us
+      do that.) Bugfix on 0.2.2.6-alpha; bug found by wanoskarnet.
+    - Add missing explanations for the authority-related torrc options
+      RephistTrackTime, BridgePassword, and V3AuthUseLegacyKey in the
+      man page. Resolves issue 2379.
+    - As an authority, do not upload our own vote or signature set to
+      ourself. It would tell us nothing new, and as of 0.2.2.24-alpha,
+      it would get flagged as a duplicate. Resolves bug 3026.
+    - Accept hidden service descriptors if we think we might be a hidden
+      service directory, regardless of what our consensus says. This
+      helps robustness, since clients and hidden services can sometimes
+      have a more up-to-date view of the network consensus than we do,
+      and if they think that the directory authorities list us a HSDir,
+      we might actually be one. Related to bug 2732; bugfix on
+      0.2.0.10-alpha.
+    - When a controller changes TrackHostExits, remove mappings for
+      hosts that should no longer have their exits tracked. Bugfix on
+      0.1.0.1-rc.
+    - When a controller changes VirtualAddrNetwork, remove any mappings
+      for hosts that were automapped to the old network. Bugfix on
+      0.1.1.19-rc.
+    - When a controller changes one of the AutomapHosts* options, remove
+      any mappings for hosts that should no longer be automapped. Bugfix
+      on 0.2.0.1-alpha.
+    - Do not reset the bridge descriptor download status every time we
+      re-parse our configuration or get a configuration change. Fixes
+      bug 3019; bugfix on 0.2.0.3-alpha.
+
+  o Minor bugfixes (code cleanup):
+    - When loading the microdesc journal, remember its current size.
+      In 0.2.2, this helps prevent the microdesc journal from growing
+      without limit on authorities (who are the only ones to use it in
+      0.2.2). Fixes a part of bug 2230; bugfix on 0.2.2.6-alpha.
+      Fix posted by "cypherpunks."
+    - The microdesc journal is supposed to get rebuilt only if it is
+      at least _half_ the length of the store, not _twice_ the length
+      of the store. Bugfix on 0.2.2.6-alpha; fixes part of bug 2230.
+    - Fix a potential null-pointer dereference while computing a
+      consensus. Bugfix on tor-0.2.0.3-alpha, found with the help of
+      clang's analyzer.
+    - Avoid a possible null-pointer dereference when rebuilding the mdesc
+      cache without actually having any descriptors to cache. Bugfix on
+      0.2.2.6-alpha. Issue discovered using clang's static analyzer.
+    - If we fail to compute the identity digest of a v3 legacy keypair,
+      warn, and don't use a buffer-full of junk instead. Bugfix on
+      0.2.1.1-alpha; fixes bug 3106.
+    - Resolve an untriggerable issue in smartlist_string_num_isin(),
+      where if the function had ever in the future been used to check
+      for the presence of a too-large number, it would have given an
+      incorrect result. (Fortunately, we only used it for 16-bit
+      values.) Fixes bug 3175; bugfix on 0.1.0.1-rc.
+    - Require that introduction point keys and onion handshake keys
+      have a public exponent of 65537. Starts to fix bug 3207; bugfix
+      on 0.2.0.10-alpha.
+
+  o Removed features:
+    - Caches no longer download and serve v2 networkstatus documents
+      unless FetchV2Networkstatus flag is set: these documents haven't
+      haven't been used by clients or relays since 0.2.0.x. Resolves
+      bug 3022.
