   their true protocol, so only a `proto: any` rule allows them. If you carry one of these protocols over the
   overlay, confirm a `proto: any` rule covers it before upgrading, it may have been passing only through this
   bypass. (#1840)
+- Drop the dependency on `github.com/cyberdelia/go-metrics-graphite`, which has been unmaintained for over ten
+  years, by inlining the small amount of code Nebula used. (#1832)
 
 ### Fixed
 
 - The ICMPv6 type was read from the wrong byte when classifying IPv6 packets, so the echo identifier used
   for conntrack was never picked up. (#1840)
+- Enforce outbound message counter limits so a tunnel is rehandshaked before the counter can wrap, preventing
+  nonce reuse. This is unreachable in practice, but is enforced as a defense-in-depth measure. (#1841)
+- Prevent `nebula-cert ca` from running out of memory on 32bit systems when generating encrypted private keys. (#1834)
+- Tolerate `ErrDumpInterrupted` when listing tun addresses on Linux, so a transient interrupted netlink dump
+  no longer aborts startup. (#1835)
