This release fixes an issue with invalid field index causing a PHP error, in case the custom field gets deleted, and a new field is added of a different type. Now field index values are removed when the field is deleted, so the invalid value is not used later.
To fix existing invalid values, rebuild custom field caches from the Rebuild Caches page:
