Merge master (#1811) and re-apply the q8 withdrawal as a REPLACEMENT

My previous merge of this branch was built by a helper that assumes a branch
ADDS a CHANGELOG entry and re-inserts it under its section. This branch does
not add one -- it REWRITES #1823's existing entry -- so the helper produced the
entry TWICE: master's uncorrected line plus the corrected one, which left the
withdrawn claim still present in the file the PR was meant to fix.

Rebuilt from master with the correction applied as an in-place replacement,
asserting both that the anchor occurs exactly once on master before the edit
and that the entry occurs exactly once after it.
