+Changes in version 0.3.2.8-rc - 2017-12-21
+  Tor 0.3.2.8-rc fixes a pair of bugs in the KIST and KISTLite schedulers
+  that had led servers under heavy load to overload their outgoing
+  connections. All relay operators running earlier 0.3.2.x versions should
+  upgrade. This version also includes a mitigation for over-full DESTROY
+  queues leading to out-of-memory conditions: if it works, we will soon
+  backport it to earlier release series.
+
+  This is the second release candidate in the 0.3.2 series. If we find no
+  new bugs or regression here, then the first stable 0.3.2 release will
+  be nearly identical to this.
+
+  o Major bugfixes (KIST, scheduler):
+    - The KIST scheduler did not correctly account for data already enqueued
+      in each connection's send socket buffer, particularly in cases when the
+      TCP/IP congestion window was reduced between scheduler calls. This
+      situation lead to excessive per-connection buffering in the kernel, and
+      a potential memory DoS. Fixes bug 24665; bugfix on 0.3.2.1-alpha.
+
+  o Minor bugfixes (scheduler, KIST):
+    - Use a sane write limit for KISTLite when writing onto a connection
+      buffer instead of using INT_MAX and shoving as much as it can. Because
+      the OOM handler cleans up circuit queues, we are better off at keeping
+      them in that queue instead of the connection's buffer. Fixes bug 24671;
+      bugfix on 0.3.2.1-alpha.
+
+  o Minor features (geoip):
+    - Update geoip and geoip6 to the December 6 2017 Maxmind GeoLite2
+      Country database.
+
+  o Minor bugfixes (hidden service v3):
+    - Bump hsdir_spread_store parameter from 3 to 4 in order to increase the
+      probability of reaching a service for a client missing microdescriptors.
+      Fixes bug 24425; bugfix on 0.3.2.1-alpha.
+
+  o Minor bugfixes (memory usage):
+    - When queuing DESTROY cells on a channel, only queue the
+      circuit-id and reason fields: not the entire 514-byte
+      cell. This fix should help mitigate any bugs or attacks that
+      fill up these queues, and free more RAM for other uses. Fixes
+      bug 24666; bugfix on 0.2.5.1-alpha.
