 Changes in version 0.2.7.2-alpha - 2015-07-??
+  o Major bugfixes (client-side privacy, also in 0.2.6.9):
+    - Properly separate out each SOCKSPort when applying stream
+      isolation. The error occurred because each port's session group was
+      being overwritten by a default value when the listener connection
+      was initialized. Fixes bug 16247; bugfix on 0.2.6.3-alpha. Patch
+      by "jojelino".
+
+  o Minor feature (directory authorities, security, also in 0.2.6.9):
+    - The HSDir flag given by authorities now requires the Stable flag.
+      For the current network, this results in going from 2887 to 2806
+      HSDirs. Also, it makes it harder for an attacker to launch a sybil
+      attack by raising the effort for a relay to become Stable which
+      takes at the very least 7 days to do so and by keeping the 96
+      hours uptime requirement for HSDir. Implements ticket 8243.
+
+  o Minor bugfixes (compilation, also in 0.2.6.9):
+    - Build with --enable-systemd correctly when libsystemd is
+      installed, but systemd is not. Fixes bug 16164; bugfix on
+      0.2.6.3-alpha. Patch from Peter Palfrader.
+
+  o Minor bugfixes (Linux seccomp2 sandbox, also in 0.2.6.9):
+    - Fix sandboxing to work when running as a relaymby renaming of
+      secret_id_key, and allowing the eventfd2 and futex syscalls. Fixes
+      bug 16244; bugfix on 0.2.6.1-alpha. Patch by Peter Palfrader.
+    - Allow systemd connections to work with the Linux seccomp2 sandbox
+      code. Fixes bug 16212; bugfix on 0.2.6.2-alpha. Patch by
+      Peter Palfrader.
+
+  o Minor bugfixes (tests, also in 0.2.6.9):
+    - Fix a crash in the unit tests when built with MSVC2013. Fixes bug
+      16030; bugfix on 0.2.6.2-alpha. Patch from "NewEraCracker".
+
+  o Major bugfixes (hidden service clients, stability, also in 0.2.6.10):
+    - Stop refusing to store updated hidden service descriptors on a
+      client. This reverts commit 9407040c59218 (which indeed fixed bug
+      14219, but introduced a major hidden service reachability
+      regression detailed in bug 16381). This is a temporary fix since
+      we can live with the minor issue in bug 14219 (it just results in
+      some load on the network) but the regression of 16381 is too much
+      of a setback. First-round fix for bug 16381; bugfix
+      on 0.2.6.3-alpha.
+
+  o Major bugfixes (stability, also in 0.2.6.10):
+    - Stop crashing with an assertion failure when parsing certain kinds
+      of malformed or truncated microdescriptors. Fixes bug 16400;
+      bugfix on 0.2.6.1-alpha. Found by "torkeln"; fix based on a patch
+      by "cypherpunks_backup".
+    - Stop random client-side assertion failures that could occur when
+      connecting to a busy hidden service, or connecting to a hidden
+      service while a NEWNYM is in progress. Fixes bug 16013; bugfix
+      on 0.1.0.1-rc.
+
+  o Minor features (geoip, also in 0.2.6.10):
+    - Update geoip to the June 3 2015 Maxmind GeoLite2 Country database.
+    - Update geoip6 to the June 3 2015 Maxmind GeoLite2 Country database.
+
+  o Minor bugfixes (crypto error-handling, also in 0.2.6.10):
+    - Check for failures from crypto_early_init, and refuse to continue.
+      A previous typo meant that we could keep going with an
+      uninitialized crypto library, and would have OpenSSL initialize
+      its own PRNG. Fixes bug 16360; bugfix on 0.2.5.2-alpha, introduced
+      when implementing ticket 4900. Patch by "teor".
+
+  o Minor bugfixes (Linux seccomp2 sandbox, also in 0.2.6.10):
+    - Allow pipe() and pipe2() syscalls in the seccomp2 sandbox: we need
+      these when eventfd2() support is missing. Fixes bug 16363; bugfix
+      on 0.2.6.3-alpha. Patch from "teor".

changes/bug16247

changes/bug16360-failed-crypto-early-init

-  o Minor bugfixes (crypto error-handling):
-    - If crypto_early_init fails, a typo in a return value from tor_init
-      means that tor_main continues running, rather than returning
-      an error value.
-      Fixes bug 16360; bugfix on d3fb846d8c98 in 0.2.5.2-alpha,
-      introduced when implementing #4900.
-      Patch by "teor".

changes/bug16363

-  o Minor bugfixes (Linux seccomp2 sandbox):
-    - Allow pipe() and pipe2() syscalls; we need these when eventfd2()
-      support is missing. Fixes bug 16363; bugfix on 0.2.6.3-alpha.
-      Patch from "teor".

changes/bug16381

-  o Major bugfix (Hidden service client)
-    - Revert commit 9407040c592184e05e45a3c1a00739c2dd302288 of bug #14219
-      that indeed fixed an issue but introduced a major hidden service
-      reachability regression detailed in bug #16381. This is a temporary
-      fix since we can live with the minor issue in #14219 but the
-      regression introduced is too much of a set back.
-
-      To be clear, #14219 bug just results in some load on the network, and
-      some delay for the client when visiting a hidden service that will
-      ultimately fail.
-
-      This is only a bandaid for #16381 thus it does _not_ fixes it. bugfix
-      on tor-0.2.6.3-alpha~138.

changes/bug16400

-  o Major bugfixes:
-   - Do not crash with an assertion error when parsing certain kinds
-     of malformed or truncated microdescriptors. Fixes bug 16400;
-     bugfix on 0.2.6.1-alpha. Found by "torkeln"; fix based on a patch by
-     "cypherpunks_backup".
