Why it matters

This feature enables users to update fields in range-hashed dictionaries, allowing more flexible and dynamic data management within these dictionary types. It solves the limitation where previously update_field was not supported for these dictionaries, improving usability and data maintenance.

How to use it

To use this feature, users can now apply the update_field operation on RangeHashedDictionary and ComplexKeyRangeHashedDictionary just as with other supported dictionaries. No additional configuration is needed beyond defining the dictionary as one of these types and using update_field in dictionary updates.
