+Changes in version 0.4.2.7 - 2020-03-??
+  This is the third stable release in the 0.4.2.x series.
+
+  Blurb.
+
+  o Major bugfixes (circuit padding, memory leak, backport from 0.4.3.3-alpha):
+    - Avoid a remotely triggered memory leak in the case that a circuit
+      padding machine is somehow negotiated twice on the same circuit.
+      Fixes bug 33619; bugfix on 0.4.0.1-alpha. Found by Tobias Pulls.
+      This is also tracked as TROVE-2020-004.
+
+  o Major bugfixes (directory authority, backport from 0.4.3.3-alpha):
+    - Directory authorities will now send a 503 (not enough bandwidth)
+      code to clients when under bandwidth pressure. Known relays and
+      other authorities will always be answered regardless of the
+      bandwidth situation. Fixes bug 33029; bugfix on 0.1.2.5-alpha.
+
+  o Minor features (continuous integration, backport from 0.4.3.2-alpha):
+    - Stop allowing failures on the Travis CI stem tests job. It looks
+      like all the stem hangs we were seeing before are now fixed.
+      Closes ticket 33075.
+
+  o Minor bugfixes (bridges, backport from 0.4.3.1-alpha):
+    - Lowercase the configured value of BridgeDistribution before adding
+      it to the descriptor. Fixes bug 32753; bugfix on 0.3.2.3-alpha.
+
+  o Minor bugfixes (hidden services v3, backport from 0.4.3.3-alpha):
+    - Fix an assertion failure that could result from a corrupted
+      ADD_ONION control port command. Found by Saibato. Fixes bug 33137;
+      bugfix on 0.3.3.1-alpha. This issue is also tracked
+      as TROVE-2020-003.
+
+  o Minor bugfixes (logging, backport from 0.4.3.2-alpha):
+    - If we encounter a bug when flushing a buffer to a TLS connection,
+      only log the bug once per invocation of the Tor process.
+      Previously we would log with every occurrence, which could cause
+      us to run out of disk space. Fixes bug 33093; bugfix
+      on 0.3.2.2-alpha.
+
+  o Minor bugfixes (rust, build, backport from 0.4.3.2-alpha):
+    - Fix a syntax warning given by newer versions of Rust that was
+      creating problems for our continuous integration. Fixes bug 33212;
+      bugfix on 0.3.5.1-alpha.
+
+  o Testing (Travis CI, backport from 0.4.3.3-alpha):
+    - Remove a redundant distcheck job. Closes ticket 33194.
+    - Sort the Travis jobs in order of speed: putting the slowest jobs
+      first takes full advantage of Travis job concurrency. Closes
+      ticket 33194.
+    - Stop allowing the Chutney IPv6 Travis job to fail. This job was
+      previously configured to fast_finish (which requires
+      allow_failure), to speed up the build. Closes ticket 33195.
+    - When a Travis chutney job fails, use chutney's new "diagnostics.sh"
+      tool to produce detailed diagnostic output. Closes ticket 32792.
