Why we make metadata updates
It's important that metadata is appropriately managed to ensure its ongoing relevancy, usefulness, and reflects the current business. For example, metadata is updated to reflect a product rebrand. Because some metadata values (slugs) are included in the YAML header, metadata updates require changes to the content itself.

For metadata used internally, these updates make reports cleaner, easier to use, more consistent, and more reflective of current business. Once changes to allowlist-driven metadata are merged, standard dashboards and reports will reflect new values. You'll need to use new filter values in those dashboards and reports. If you have custom dashboards or Kusto queries, you might need to update those as well.

For customer-facing metadata, these updates ensure our customers are seeing the most up-to-date metadata on Learn content that matches what they see elsewhere in the Microsoft universe.

Why we make header/navigation updates
Header changes and other site navigation updates are crucial for improving content findability and are made in support of the navigation model strategy driven by the Learn Information Architecture and Content Architecture teams.

After you accept the header/navigation changes, you may now see a new or different product-level header used on content in your repo, revised breadcrumbs, or other navigation-related changes, which will be specified in the commit message.
