+The [Extract Property](https://cumulocity.com/docs/streaming-analytics/block-reference/#extract-property) block in Analytics Builder now includes a new optional checkbox called **Ignore Separators In Property Path**. This allows you to extract a property that has a separator such as a period (.) in the property name.
+For example, if the **Ignore Separators In Property Path** checkbox is selected and the **Property Path** parameter is specified as `location.city`, then the property name `location.city` is extracted from the input value.
+For compatibility, the previous behavior remains as the default, that is, the new checkbox is not selected by default.
