Thanks everyone for their verification.
Any plans for a Wildfly 12.1 release or a patch file provided by Weld 3.0.4 for Wildfly 12?
You can check the releases page here on JIRA to see planned releases. We are usually running in a so-so 3 months windows. 3.0.4.Final is now planned for mid-May.
With every release we also provide a patch for WildFly and this release will be no exception to that.
There won't be WildFly 12.1, so you need to either patch the current one once we release it, or just wait for WildFly 13.
