### Retro-compatibility (existing users coming from the old version of JCT to the version released on 12/30/2025 )

In previous versions of JCT, labels were global (no grouping).  
After upgrade:

- All existing old labels will appear under an **“Ungrouped”** group
- The “Ungrouped” group will be automatically assigned to all projects
- Admins can later create new groups
- Labels can be moved from “Ungrouped” into the new groups as needed

> ⚠️ **Retro-compatibility note:** This module cannot be unassigned/detached from all the spaces it is already assigned to. It must remain associated with at least one existing space.
> ⚠️ 
> ⚠️ => This ensures zero breakage for existing usage.
