+[v2.4.1][UNRELEASED]
+-----------------------
+
+### Changes
+- Fake microsecond timestamp to allow for improved log sorting:
+  - in RFC3164 messages (that don't have this resolution)
+  - in untrusted kernel messages
+- Dropped `debian/` directory (moved to separate branch), to ease
+  re-packaging by downstream
+
+### Fixes
+- Fix #52: Prevent over-read when scanning a new-style kernel message.
+  Found and fixed by Edward K. McGuire
+- Fix #53: prevent log file corruption when kernel messages contain
+  control codes, notably `\n`.  Instead, preserve kernel protective
+  C-style hex encoding.  For example, `\n` embedded in a message by a
+  kernel-level facility is received as `\x0a`.  Found and fixed by
+  Edward K. McGuire
+- Fix #56: logging to remote machine stops after receiving a few
+  SIGHUPs.  Open remote socket count was not reset properly on SIGHUP.
+  Problem introduced in v2.4.0.  Reported by Edward K. McGuire
