Thank you very much for the fixes! Your PR will be included in automatically generated release notes by GitHub. To make sure that is clean, could you:

• Tweak PR title descriptiveness/format (e.g. Fix typos in documentation)
• Include a description. In this case, it may be a copy/paste of the title

There is also a hand-updated file at doc/changelog.md that is required to pass our automated build checks. If you add the updated title to the change list under To be released at some point in the future, you'll be set to merge.

LGTM!
