Release v3.8.0

[glatterf42]

Preparing the 3.8.0 release.

• Read the diff and note that the CI checks all pass.
• Run a specific code snippet or command and check the output.
• Build the documentation and look at a certain page.
• Ensure that changes/additions are self-documenting, i.e. that another
  developer (someone like the reviewer) will be able to understand what the code
  does in the future.

PR checklist

• Continuous integration checks all ✅
• [ ] Add or expand tests; coverage checks both ✅
• Add, expand, or update documentation.
• Update release notes.
