 ## Prep
-- Update `CHANGELOG.md` with release notes and date.
-  The release workflow extracts notes from a `## vX.Y.Z - YYYY-MM-DD` section.
 - Bump versions in `Cargo.toml` (workspace and crates) as needed.
 - Ensure `Cargo.lock` is updated and committed.
 - Confirm vendor/picoquic is at the intended commit and submodules are initialized.
