Nov 1, 2024November 2024 – gsainfoteam/groups-be: Group management API improvements focusing on UUID handling and invitation flow. Implemented Group Invitation and Group Data UUID Handling Improvements: removed mandatory user UUID for group invitation info retrieval, clarified group data retrieval by requiring a user UUID where appropriate, introduced optional user UUID for getGroupByUuidWithUserUuid, and renamed the function to reflect the parameter usage. This refactor enhances API clarity, flexibility, security, and client integration readiness. No explicit bug fixes recorded; changes reduce edge-case issues and improve maintainability.
