+## Configuration
+
+The `mod_mam_meta` module is now named `mod_mam` for simplicity, so if you are using this module, you need to update the module name in `mongooseim.toml`.
+
+## Metrics
+
+The `mod_mam` backend module is now named `mod_mam_pm` for consistency with `mod_mam_muc`. As a result, the backend metrics have updated names, i.e. each `[backends, mod_mam, Metric]` name is changed to `[backends, mod_mam_pm, Metric]`, where `Metric` can be `lookup` or `archive`.
