February 2025 monthly summary for zextras/carbonio-calendars-ui: Focused on improving search reliability by fixing phrase quoting in the UI search flow.

This resolves incorrect results caused by unquoted phrases and aligns with CO-1458. Commit 7258289ab0aa970e3ff0a5a766152bb7917ce1bb: fix(CO-1458): quote query chip in case of phrase (#555).

In 2024-10, the team delivered targeted improvements to calendar group creation within zextras/carbonio-mailbox, focusing on correctness, error clarity, and maintainability. Key changes include the new createUniqueGroupElement to distinguish unique vs non-unique group elements, refactoring createGroupElement to delegate to addNonUniqueElement, and updating CreateCalendarGroup/ModifyCalendarGroup to use the new path. A new DuplicateCalendarGroupNameException was introduced with tests to provide clearer feedback when a calendar group name already exists. These changes reduce duplication errors, improve reliability of calendar grouping operations, and enhance test coverage, supporting a more robust user experience and easier future maintenance.
