  • ⚠️ check the package-lock.json content, only "boosted" should have its version changed!

• run build/ship.sh x.x.x to… (v4 only)
• npm pack then npm publish
  • if you are already logged in NPM (with a personnal account, for example), you'd better use a repository scoped .npmrc file
  • if you're releasing a pre-release, use --tag, eg for v5-alpha1 npm publish boosted-5.0.0-alpha1.tgz --tag next
• publish on Nuget
• check release on NPM, Nuget, Packagist…
• publish documentation on gh-pages:
  • copy ../_site (v5-dev) or ../bs-docs (v4-dev) to the gh-pages branch
  • check every index.html used as redirections to be redirecting to the new release
  • when bumping minor version: ensure dist URLs in examples' HTML has changed
  • double-check everything before pushing, starting by searching for forgotten old version number occurences
• make an announcement in Plazza 🎉
