Weld 3.1.2.Final is coming along with Weld API 3.1.SP1. It is another small release bringing in mainly bugfixes. One notable thing is that thanks to guys from Jetty, Weld 3.1.2.Final is ready to operate with lastest Jetty 9 as well as upcoming Jetty 10. Other than that we have tried to address some dodgy issues with possible race conditions and leaks - see for yourself!
