 - `tests.overriding` has its `passthru.tests` restructured as an attribute set instead of a list, making individual tests accessible by their names.
 
+- Package `skk-dict` was split into multiple packages under `skkDictionaries`.
+  If in doubt, try `skkDictionaries.l`. As part of this change, the dictionaries
+  were moved from `$out/share` to `$out/share/skk`. Also, the dictionaries won't
+  be converted to UTF-8 unless the `useUtf8` package option is enabled. UTF-8
+  converted dictionaries will have the .utf8 suffix appended to its filename.
+
 - `vaultwarden` lost the capability to bind to privileged ports. If you rely on
    this behavior, override the systemd unit to allow `CAP_NET_BIND_SERVICE` in
    your local configuration.
