Summary:
The navigation section of browse mode (technical project name) is being removed for 6.2 RC 2. This does not impact the additional way of managing your menus within the block settings of the Navigation block. This was a joint decision across core editor tech leads, core editor triage leads, and the design lead. Thank you to everyone who helped test, open issues, share designs, and ship PRs to both move this feature forward and make this decision to remove. It sets a strong foundation for reconsideration in future releases and work will continue with the feature remaining in the Gutenberg plugin to evolve.
