Yes. Yes. Yes. A million times, yes. I can't stress this enough: always put visible timestamps on all content (be it web or otherwise, online or offline) and current version number for any kind of software (apps, libraries, frameworks, etc.) on their info / landing / documentation pages. It should be immediately visible if a certain content is dated or not.

Some examples of software-related landing pages:

https://sindresorhus.com/caprine/ (Caprine app) - shows current version number

https://riot.js.org/ (Riot.js framework) - shows NPM badge with latest version number

... it's not so hard now, is it?
