Ouch, this escaped our QA. We added the LinkText= and PartialLinkText= statements for improved Selenium IDE compatibility, but broke Link= by mistake. This is a bug that will be fixed ASAP.
Meanwhile, the solution is to simply change the command from “Link=” to “LinkText=” then your macro(s) work again!
(About the versions: There was never a public V5.1.4, the latest stable version before this is indeed V5.0.8)
