 ### Look Back, Way Back
 
-Published and private APIs change over time. But deprecated or older version may still be operational either on purpose or by misconfiguration. These should also be tested as there is a good chance that they will contain vulnerabilities that newer versions have fixed. In addition, changes to APIs show newer features which may be less robust and therefore a good candidate for testing.
+In general APIs change over time. But deprecated or older version may still be operational either on purpose or by misconfiguration.

 To discover older version we can use the `Wayback machine` to help find older endpoints. A helpful tool know as TomNomNom's [WayBackUrls](https://github.com/tomnomnom/waybackurls) fetches all the URLs that the Wayback Machine knows about for a domain.
