Five years ago we migrated the Jetty project from The Codehaus to the Eclipse Foundation. In that time we have pushed out 101 releases of Jetty 7 and Jetty 8, double that if you count the artifacts that had to remain at the Codehaus for the interim.
Four years ago we ceased open source support for Jetty 6.
Two years ago we released the first milestone of Jetty 9 and there have been 34 releases since. Jetty 9 has been very well received and feedback on it has been overwhelmingly positive from both our client community and the broader open source community. We will continue to improve upon Jetty 9 for years to come and we are very excited to see how innovative features like HTTP/2 support play out as these rather fundamental changes take root. Some additional highlights for Jetty 9 are: Java 7+, Servlet 3.1+, JSR 356 WebSocket, and SPDY! You can read more about Jetty 9.2 from the release blog here. Additionally we will have Jetty 9.3 releasing soon which contains support for HTTP/2!
This year will mark the end of our open source support for Jetty 7 and Jetty 8. Earlier this week we pushed out a maintenance release that only had a handful of issues resolved over the last five months so releases have obviously slowed to a trickle. Barring any significant security related issue it is unlikely we will see more then a release or two remaining on Jetty 7 and Jetty 8. We recommend users update their Jetty versions to Jetty 9 as soon as they are able to work it into their schedule. For most people we work with, the migration has been trivial, certainly nothing on the scale of the migration between foundations.
