Superseded by #915, which combined all 22 pending release-notes PRs into one changelog update, placed in chronological order. The apps-0.2.103 entry is on main, with the sub-client redirect URI note reworded to stay high level (the specific configuration option is no longer named). Closing as merged-by-proxy; the branch is left in place.
