Version 5.5.2 2025-09

Version 5.5.2 2025-09

• This is a hotfix for 5.5.1, which fixed something desirable, but introducing a lot of potential side effects by enforcing cardinality on RelationshipFrom.
• Until version 6.0, RelationshipFrom cardinality will be softly checked by default, only giving a warning. You can switch that using SOFT_INVERSE_CARDINALITY_CHECK=False
• Version 6.0 will make all checks strict by default.
