+[v2.5.0][] - 2023-04-30
+-----------------------
+
+### Changes
+- Issue #59: initial port to NuttX, contributed by Xiaomi
+- Issue #61: add support for `-c` and `-cc` to disable log compression.
+  A single `-c` disables compression for pipes, another `-c` (or `-cc`)
+  disables compression for all other log targets
+- The default `syslog.conf` now logs debug messages again (disabled in
+  v2.4.0) due to problems (confusion) reported in the field
+- Dropped not recommended `KillMode=process` from systemd unit file
+
+### Fixes
+- Issue #60: document how to set side-wide permissions on log files
+- Issue #62: early log messages lost when running under systemd, found
+  by Wind River Systems, including initial fix
+
