+Since TYPO3 6.2, 7.6 and 8.7 are EOL now, this extension is going to retire. What does it mean?
+
+1. There will be no new features anymore unless they are sponsored.
+1. There will be bug fixes from time to time. Also you can [sponsor](mailto:[email protected]) a bug fix if you really need it. Otherwise you can
+add it to the issue tracker and hope to be fixed :)
+
+I am sorry but after developing and supporting this most popular TYPO3 extension mostly for free since 2006,
+I have to stop at some point.
