-### Breaking changes
-* Configuration property `forecast_days` was renamed to `forecast_rows` to indicate that this attribute does not only work for daily, but also for hourly forecasts.
-* `date-fns` has been replaced by `luxon` for date/time formatting. If you configure `date_pattern`, make sure to migrate your pattern to comply with [luxon](https://moment.github.io/luxon/#/formatting?id=table-of-tokens). Additionally, the weekday is now [_not_ hardcoded](https://github.com/pkissling/clock-weather-card/issues/89) anymore.
-* Configuration property `use_browser_time` is now by default `false`, so by default the card will show the time of the current HA time zone.
+* Configuration property `forecast_days` was renamed to `forecast_rows` to indicate that this property not only applies for daily, but also for hourly forecasts.
+* `date-fns` library has been replaced in favor of `luxon` for date/time formatting. If you provide a custom `date_pattern`, make sure to migrate the pattern from `date-fns` tokens to the [luxon pattern](https://moment.github.io/luxon/#/formatting?id=table-of-tokens). Additionally, [_not_ hardcoded weekdays being prepended to the date](https://github.com/pkissling/clock-weather-card/issues/89) have been removed. If you still want the weekday to be prepended, you have to specify the following pattern: `ccc, DD`.
+* Configuration property `use_browser_time` is now by [default](https://github.com/pkissling/clock-weather-card/issues/157) `false`, so by default the card will show the time of the current HA time zone.
