- babel-preset-env, @babel/preset-env
  babel-preset-env moved to @babel/preset-env in the Babel monorepo.
  This appears to have incremented the version from v1.6.0[0] to 7.x to
  match the rest of the Babel packages but appears to otherwise be
  undocumented.[1,3]

- @babel/preset-env, @babel/register
  *Many* changes as identified by package [2] and summarized [3].

  Node.js v6 or above now required.

  New dependency on @babel/core.

  Support for ES2018 and browserslist v4.

  `modules: false` is now the default for preset-env + babel-loader. The
  .babelrc has been updated.

  New babel-upgrade tool.

  babel.config.js can replace .babelrc. Popups doesn't seem to need it.

- babel-loader
  Support for Babel 7.x.

  The following warning is printed when building but perhaps this is due
  to another dependency:

    (node:14559) DeprecationWarning: loaderUtils.parseQuery() received a
    non-string value which can be problematic, see
    https://github.com/webpack/loader-utils/issues/56 parseQuery() will
    be replaced with getOptions() in the next major version of
    loader-utils.

Stephen Niedzielski e5df865d51 Hygiene: enable Babel transpilation
Enable the Babel transpiler so that ES6 template literals,
destructuring, and arrow functions can be used in production.
"last n versions" syntax was not used so that builds are more
reproducible.
