Today I used the [new release script](https://github.com/facebook/react/tree/master/scripts/release) for the first time to publish `16.1.0-beta`. Here are a couple of things I noticed that I want to follow-up on:

### PR #11434
- [x] Auto-install (or update) release script Yarn deps before running

### PR #11437
- [x] `publish` script should `git tag -a ${version}`. I manually tagged the `16.1.0-beta` release.
- [X] The post-build test instructions should show fully-qualified paths to prevent you from accidentally verifying the wrong build (eg the checkout the release script is running from rather than the `-p` path)
- [x] `publish-to-npm` check should handle pre-1.0 packages. (This one failed for the `0.2.0` reconciler release b'c it expected it to be 16.1.0-beta.) For that matter, it should have probably been `0.2.0-beta`
- [x] When publishing a stable release (`@latest`) also update the next release to point to it.
'https://github.com/facebook/react/edit/master/CHANGELOG.md';
module.exports = params => {
  const command =
    `./publish.js -v ${params.version}` +
    (params.path ? ` -p ${params.path}` : '') +
    (params.dry ? ' --dry' : '');
  console.log(
    chalk`
    {green.bold Build successful!}
    ${getUnexecutedCommands()}
    Next there are a couple of manual steps:
    {bold.underline Step 1: Update the CHANGELOG}
    Here are a few things to keep in mind:
    • The changes should be easy to understand. (Friendly one-liners are better than PR titles.)
    • Make sure all contributors are credited.
    • Verify that the markup is valid by previewing it in the editor: {blue.bold ${CHANGELOG_PATH}}
    {bold.underline Step 2: Smoke test the packages}
    1. Open {yellow.bold fixtures/packaging/babel-standalone/dev.html} in the browser.
    2. It should say {italic "Hello world!"}
    3. Next go to {yellow.bold fixtures/packaging} and run {bold node build-all.js}
    4. Install the "serve" module ({bold npm install -g serve})
    5. Go to the repo root and {bold serve -s .}
    6. Open {blue.bold http://localhost:5000/fixtures/packaging}
    7. Verify every iframe shows {italic "Hello world!"}
    After completing the above steps, resume the release process by running:
    {yellow.bold ${command}}
  `.replace(/\n +/g, '\n')
  );
};
