I use primeng UI components 1.1.1 version for angular. But on their site (https://www.primefaces.org/primeng) 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).
