v4.14.1

Fixed

• Fixed Entities::upsert_entities keeping a stale ancestor when the same entity is given more than once in one batch.
• The policy formatter no longer puts a line break between a method name and its argument list when it splits a long attribute access chain (#2119).
• Policy::to_cedar() and PolicySet::to_cedar() now return None for policies and templates (e.g., from JSON) that cannot be represented in Cedar syntax, such as a method-style extension function call with no receiver ({"offset": []}) or an extended has with a non-identifier attribute. Previously they returned Cedar text that failed to parse (#2116).
