Changeset text becomes user-facing CHANGELOG, so the #429 entry is cut
from five bullets of internal bash-array detail down to what the change
does for someone running the installer, as promised on the PR. The #441
entry loses its em-dashes, which are not house style. Adds an entry for
the maintainer fixes applied while landing #442, and the Thanks section.
