• The Ang5-compatible bootstrap library ng-bootstrap supports BS4 only.
• Version 4 is mostly backward compatible with version 3.
• The "panel" is no more – replaced with "card".
• Glyphicons are deprecated (and have license restrictions). BS suggests some alternatives.

  • I tested the Google Material Icons and they work well and use an Apache 2 license. Attribution is optional.

• The utility classes have been expanded
  • https://getbootstrap.com/docs/4.0/utilities/
  • Margins, padding, text, colors, borders, and more!
  • These remove the need to write a lot of local CSS. Want a small amount of margin up top? class="mt-1"

1. Angular5 (well, ng-cli) uses Webpack by default.
2. May be implemented independent of any Ang5 upgrade plans.
3. Improved options for creating of JS, etc. bundles
4. Can be implemented in low-impact phases.
   1. Phase I: Use webpack as a drop-in replacement for Grunt for compiling builds (and use npm to run karma unit tests).
      1. No application code changes are required.
      2. I have a branch that does this (plus Angular 1.6 – https://bugs.launchpad.net/evergreen/+bug/1739803 [pushed to 3.1-beta])
   2. Phase II: Start using ES6-style module 'import' statements for specifying dependencies.
      1. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import
      2. These ultimately replace <script/> imports
