ChangeLog

+Changes in version 0.4.7.8 - 2022-06-17
+  This version fixes several bugfixes including a High severity security issue
+  categorized as a Denial of Service. Everyone running an earlier version
+  should upgrade to this version.
+
+  o Major bugfixes (congestion control, TROVE-2022-001):
+    - Fix a scenario where RTT estimation can become wedged, seriously
+      degrading congestion control performance on all circuits. This
+      impacts clients, onion services, and relays, and can be triggered
+      remotely by a malicious endpoint. Tracked as CVE-2022-33903. Fixes
+      bug 40626; bugfix on 0.4.7.5-alpha.
+
+  o Minor features (fallbackdir):
+    - Regenerate fallback directories generated on June 17, 2022.
+
+  o Minor features (geoip data):
+    - Update the geoip files to match the IPFire Location Database, as
+      retrieved on 2022/06/17.
+
+  o Minor bugfixes (linux seccomp2 sandbox):
+    - Allow the rseq system call in the sandbox. This solves a crash
+      issue with glibc 2.35 on Linux. Patch from pmu-ipf. Fixes bug
+      40601; bugfix on 0.3.5.11.
+
+  o Minor bugfixes (logging):
+    - Demote a harmless warn log message about finding a second hop to
+      from warn level to info level, if we do not have enough
+      descriptors yet. Leave it at notice level for other cases. Fixes
+      bug 40603; bugfix on 0.4.7.1-alpha.
+    - Demote a notice log message about "Unexpected path length" to info
+      level. These cases seem to happen arbitrarily, and we likely will
+      never find all of them before the switch to arti. Fixes bug 40612;
+      bugfix on 0.4.7.5-alpha.
+
+  o Minor bugfixes (relay, logging):
+    - Demote a harmless XOFF log message to from notice level to info
+      level. Fixes bug 40620; bugfix on 0.4.7.5-alpha.
