Merge master into docs/withdraw-q8-win-claim-1825

Only CHANGELOG.md changed on both sides. Resolved structurally rather than
textually: master's file taken whole, this branch's entries re-inserted under
the same '###' section they occupied on the branch. Every other branch file
carries through unchanged.
