+1 this would be useful to keep things updated, seeing as this currently causes warnings when trying to update angular projects.

Hi,

We apologise that you had to wait so long for a response. We have prepared a new version of our library. This repository has been updated and the library can be found on NPM https://www.npmjs.com/package/@livechat/angular-widget.

Please give it a try and if necessary open new issue.
