 * RRDP data is now collected into the same key-value database. The new
   command `dump` allows copying the data from the database to the file
   system. ([#473], [#480], [#484])
+* If an RRDP repository is unavailable for a certain time, Routinator will
+  now fall back to rsync. The time since last successful update before
+  this fallback happens is configurable via the `rrdp-fallback-time`
+  option and defaults to one hour. ([#473], [#482])
 * The minimal supported Rust version is now 1.44.0. [(#444)]
