+description: When using the `release-notes/_snippets` model, there are multiple levels of nesting to make it as easy as possible to insert new patch version sections in the correct order. The updates in this PR will (1) eliminate any manual steps in the resulting release notes PR outside of copy edits, and (2) reduce the chance of conflicts when forward porting to later minors and `main`.
