• Fixed: offline.appcache option was supporting a bunch of options that
  were completely ignored.
  We removed this useless options.
  This might looks like a breaking change, but we prefer to warn you that you
  are using things that don't do anything.

• Fixed: offline option has been fixed to provide a network first approach
  like documentation is saying.
  (It was "cache first" since 0.15.0). If that's the behavior you want to keep,
  please open an issue so we can discuss about that. We think cache-first does
  not provide a good UX when it comes to update the content.

• Fixed: direct access to url (from the address bar) containing a dot in
  development
  (@MoOx)
• Added: new force-offline option, to force offline mode during
  development
