title: where can I find documentation for specific version
body: <p>I use primeng UI components 1.1.1 version for angular. But on their site (<a href="https://www.primefaces.org/primeng" rel="nofollow noreferrer">https://www.primefaces.org/primeng</a>) I can find documentation only for the latest version.
  Where I can find documentation for specific older versions? I do not want to upgrade to the latest version as I can corrupt something in my project. Besides new versions of the components are released quite often.
  Now with my version I have problems with development (get some errors) as I do not know which features are supported (as I can only reference to the latest version on their site).</p>
