what is the good practice of providing version info to end users in Web application?

I see that not all Web applications would provide version info to end users. If a Web application does, the version is displayed at the bottom of the home page, like Magento and Prestashop etc.

I am building an ASP.NET MVC application, and would provide version info. My first thought was that the assembly/file version of the entry assembly of the MVC project could be the application version, however, altering CSHTML, javascript, CSS, as well as upgrading 3rd party dependencies like jQuery and Bootstrap may result in features changes.

Are there some conventional or best practices to management version numbers to be presented somewhere in the Web application?
