Full release notes for 2.4.0

Release notes from github.com/traefik/traefik/blob/master/CHANGELOG.md, and Migration: Steps needed between the versions (v2.11 documentation), checked 17 hours ago. Only text the vendor marks as breaking, or puts in a warning/caution/important note, is shown; read the full notes for anything else. Traefik's release notes (CHANGELOG.md, GitHub releases) are lists of merged pull requests and mark nothing as breaking. What is quoted instead is Traefik's migration documentation on doc.traefik.io: “Migration: Steps needed between the versions” (v3), the same page of the v2.11 documentation (v2), and “Configuration Details for Migrating from Traefik v2 to v3” (on 3.0.0). Each section of those pages is labelled “Migration” and shown on the release its heading names (“v3.3 to v3.4” on 3.4.0). A section naming a canceled release (v2.4.10, v2.9.0) is shown on the next release of that line. Versions are covered from 2.0.0. No required stop is documented.
