We're missing packages here: utils, system, material-nextjs, material-pigment-css, the styled engine ones, and private theming

Also missing this from the CHANGELOG: 8efd596

Isn't the changelog generated based on what packages have changes? Is there something else needed to be done?

Edit: The release changelog script omits the commits for the [website], the logic was added in #44069

Yeah but all the packages that follow Material versioning (6.4.3 -> 6.4.4) should be bumped regardless of changes, that's what we've always done: https://github.com/mui/material-ui/blob/HEAD/scripts/README.md#release:~:text=Keep%20the%20package%20versions%20of%20stable%20public%20packages%20the%20same%20as%20the%20root%20package.json%20version.

I don't think this is correct. We said if a package is not updated in one release, next time it would be bumped to match the version of the root's package.json. This is how lerna works, otherwise we will need to always manually update all packages.

Ok, that's fine by me. I'll update the release instructions 👍🏼
