Weld 5.0.0.Beta1 implementing CDI 4 RC release is now available in Central.
It comes along with Weld API version 5.0.Beta5.
I have written a release notes/blog post on what's new in Weld 5,
especially in terms of major changes and what integrators need to perform
in order to fully implement the latest CDI with Weld.
It is available here -
I have tested the integration with WildFly as a proof of concept (locally
as they aren't yet accepting EE 10 contributions into main branch) but of
course your mileage may vary so if you encounter any problems or
shortcoming, do reach back via weld-dev mailing list and we can discuss it.
