+breaking changes. **Please read them before running the migration.**
!!! note
If you are migrating from a version <3.6, then you still have to follow
the manual migration steps up to 3.6.
-## 3.6.0 -> master
+## 3.6.0 -> 3.7.0
+
+### New format and name of configuration file
+
+The configuration for an import is now saved in a `.env` file in the project
+directory. This file follows the dotenv format. For more information, see
+the [installation chapter](Import.md#configuration-setup-in-env).
+
+To migrate to the new system, create a new project directory, add the `.env`
+file and port your custom configuration from `settings/local.php`. Most
+settings are named similar and only have received a `NOMINATIM_` prefix.
+Use the default settings in `settings/env.defaults` as a reference.
### New location for data files
`./utils/query.php` no longer exists in its old form. `nominatim search`
provides a replacement but returns different output.
+### Switch to normalized house numbers
+
+The housenumber column in the placex table uses now normalized version.
+The automatic migration step will convert the column but this may take a
+very long time. It is advisable to take the machine offline while doing that.
