jsxBracketSameLine was deprecated in Prettier 2.4 in favor of bracketSameLine, which applies to HTML and Vue as well as JSX, and it was removed in Prettier 3.0. A configuration still using the old name fails with an unknown option error rather than being ignored.

The replacement takes the same boolean and does the same thing for JSX: when true, the closing > of a multi-line opening tag goes on the last line of attributes instead of on its own line.

Two other options were dropped in the same release and are worth checking for at the same time: the jsxWhitespaceSensitivity handling folded into existing options, and --loglevel replaced by --log-level on the CLI. Running prettier --help on the installed version lists exactly what the binary accepts, which is faster than reconciling a config against release notes.
