+Changes in version 0.4.7.5-alpha - 2022-03-25
+  This version contains, of what we hope, the final work for congestion
+  control paving the way to the stable version. We expect this to be the last
+  alpha version of the 0.4.7.x series. Mostly minor bugfixes except one major
+  bugfix that changes how Tor behaves with DNS timeouts for Exit relays. As
+  always with an alpha, we recommend all relay operators to upgrade from
+  previous alpha to this one.
+
+  o Major bugfixes (onion service, congestion control):
+    - Fix the onion service upload case where the congestion control
+      parameters were not added to the right object. Fixes bug 40586;
+      bugfix on 0.4.7.4-alpha.
+
+  o Major bugfixes (relay, DNS):
+    - Lower the DNS timeout from 3 attempts at 5 seconds each to 2
+      attempts at 1 seconds each. Two new consensus parameters were
+      added to control these values. This change should improve observed
+      performance under DNS load; see ticket for more details. Fixes bug
+      40312; bugfix on 0.3.5.1-alpha.
+
+  o Minor features (control port):
+    - Provide congestion control fields on CIRC_BW and STREAM control
+      port events, for use by sbws. Closes ticket 40568.
+
+  o Minor features (fallbackdir):
+    - Regenerate fallback directories generated on March 25, 2022.
+
+  o Minor features (geoip data):
+    - Update the geoip files to match the IPFire Location Database, as
+      retrieved on 2022/03/25.
+
+  o Minor bugfixes (DNSPort, dormant mode):
+    - A request on the DNSPort now wakes up a dormant tor. Fixes bug
+      40577; bugfix on 0.3.5.1-alpha.
+
+  o Minor bugfixes (metrics port, onion service):
+    - Fix the metrics with a port label to be unique. Before this, all
+      ports of an onion service would be on the same line which violates
+      the Prometheus rules of unique labels. Fixes bug 40581; bugfix
+      on 0.4.5.1-alpha.
+
+  o Minor bugfixes (onion service congestion control):
+    - Avoid a non-fatal assertion failure in the case where we fail to
+      set up congestion control on a rendezvous circuit. This could
+      happen naturally if a cache entry expired at an unexpected time.
+      Fixes bug 40576; bugfix on 0.4.7.4-alpha.
+
+  o Minor bugfixes (onion service, client):
+    - Fix a rare but fatal assertion failure due to a guard subsystem
+      recursion triggered by the onion service client. Fixes bug 40579;
+      bugfix on 0.3.5.1-alpha.
+
+  o Minor bugfixes (relay, overload):
+    - Decide whether to signal overload based on a fraction and
+      assessment period of ntor handshake drops. Previously, a single
+      drop could trigger an overload state, which caused many false
+      positives. Fixes bug 40560; bugfix on 0.4.7.1-alpha.
+
