+Changes in version 0.2.4.22 - 2014-05-16
+ Tor 0.2.4.22 backports numerous high-priority fixes from the Tor 0.2.5
+ alpha release series. These include blocking all authority signing
+ keys that may have been affected by the OpenSSL "heartbleed" bug,
+ choosing a far more secure set of TLS ciphersuites by default, closing
+ a couple of memory leaks that could be used to run a target relay out
+ of RAM, and several others.
+
+ o Major features (security, backport from 0.2.5.4-alpha):
+ - Block authority signing keys that were used on authorities
+ vulnerable to the "heartbleed" bug in OpenSSL (CVE-2014-0160). (We
+ don't have any evidence that these keys _were_ compromised; we're
+ doing this to be prudent.) Resolves ticket 11464.
+
+ o Major bugfixes (security, OOM):
+ - Fix a memory leak that could occur if a microdescriptor parse
+ fails during the tokenizing step. This bug could enable a memory
+ exhaustion attack by directory servers. Fixes bug 11649; bugfix
+ on 0.2.2.6-alpha.
+
+ o Major bugfixes (TLS cipher selection, backport from 0.2.5.4-alpha):
+ - The relay ciphersuite list is now generated automatically based on
+ uniform criteria, and includes all OpenSSL ciphersuites with
+ acceptable strength and forward secrecy. Previously, we had left
+ some perfectly fine ciphersuites unsupported due to omission or
+ typo. Resolves bugs 11513, 11492, 11498, 11499. Bugs reported by
+ 'cypherpunks'. Bugfix on 0.2.4.8-alpha.
+ - Relays now trust themselves to have a better view than clients of
+ which TLS ciphersuites are better than others. (Thanks to bug
+ 11513, the relay list is now well-considered, whereas the client
+ list has been chosen mainly for anti-fingerprinting purposes.)
+ Relays prefer: AES over 3DES; then ECDHE over DHE; then GCM over
+ CBC; then SHA384 over SHA256 over SHA1; and last, AES256 over
+ AES128. Resolves ticket 11528.
+ - Clients now try to advertise the same list of ciphersuites as
+ Firefox 28. This change enables selection of (fast) GCM
+ ciphersuites, disables some strange old ciphers, and stops
+ advertising the ECDH (not to be confused with ECDHE) ciphersuites.
+ Resolves ticket 11438.
+
+ o Minor bugfixes (configuration, security):
+ - When running a hidden service, do not allow TunneledDirConns 0:
+ trying to set that option together with a hidden service would
+ otherwise prevent the hidden service from running, and also make
+ it publish its descriptors directly over HTTP. Fixes bug 10849;
+ bugfix on 0.2.1.1-alpha.
+
+ o Minor bugfixes (controller, backport from 0.2.5.4-alpha):
+ - Avoid sending a garbage value to the controller when a circuit is
+ cannibalized. Fixes bug 11519; bugfix on 0.2.3.11-alpha.
+
+ o Minor bugfixes (exit relay, backport from 0.2.5.4-alpha):
+ - Stop leaking memory when we successfully resolve a PTR record.
+ Fixes bug 11437; bugfix on 0.2.4.7-alpha.
+
+ o Minor bugfixes (bridge client, backport from 0.2.5.4-alpha):
+ - Avoid 60-second delays in the bootstrapping process when Tor is
+ launching for a second time while using bridges. Fixes bug 9229;
+ bugfix on 0.2.0.3-alpha.
+
+ o Minor bugfixes (relays and bridges, backport from 0.2.5.4-alpha):
+ - Give the correct URL in the warning message when trying to run a
+ relay on an ancient version of Windows. Fixes bug 9393.
+
+ o Minor bugfixes (compilation):
+ - Fix a compilation error when compiling with --disable-curve25519.
+ Fixes bug 9700; bugfix on 0.2.4.17-rc.
+
+ o Minor bugfixes:
+ - Downgrade the warning severity for the the "md was still
+ referenced 1 node(s)" warning. Tor 0.2.5.4-alpha has better code
+ for trying to diagnose this bug, and the current warning in
+ earlier versions of tor achieves nothing useful. Addresses warning
+ from bug 7164.
+
+ o Minor features (log verbosity, backport from 0.2.5.4-alpha):
+ - When we run out of usable circuit IDs on a channel, log only one
+ warning for the whole channel, and describe how many circuits
+ there were on the channel. Fixes part of ticket 11553.
+
+ o Minor features (security, backport from 0.2.5.4-alpha):
+ - Decrease the lower limit of MaxMemInCellQueues to 256 MBytes (but
+ leave the default at 8GBytes), to better support Raspberry Pi
+ users. Fixes bug 9686; bugfix on 0.2.4.14-alpha.
+
+ o Documentation (backport from 0.2.5.4-alpha):
+ - Correctly document that we search for a system torrc file before
+ looking in ~/.torrc. Fixes documentation side of 9213; bugfix on
+ 0.2.3.18-rc.
+
+
Changes in version 0.2.4.21 - 2014-02-28
Tor 0.2.4.21 further improves security against potential adversaries who
find breaking 1024-bit crypto doable, and backports several stability
