+Changelog
+=========
+
+11.0.2.0.0 (2021-08-21)
+~~~~~~~~~~~~~~~~~~~~~~~
+
+- Now depend on l10n_nl_country_states to prevent conflicts with that module;
+- No manual caching of province data. It complicates code and performance gain
+  will almost certainly be negligible;
+- Check valid Api Key in configuration immediately when setting or updating key;
+- Take into account that with l10n_nl_country_states installed, state_id on partner
+  will in many cases be set, even if postcode api not active, or cannot find
+  address;
+- Adjust tests to run properly on databases already containing data.
