I don't fully understand your question. WildFly is a community project and is free for use and available in openly accessible Maven repos.

JBoss EAP on the other hand is a product, certain versions of which are available under a paid subscription and certain versions of which have been made available under the developer program for free to use outside a production environment.

WildFly is 'only' a renaming of JBossAS to be more clear what is the community and the EAP version.

The current EAP6 is based on JBossAS7.x, the latest version of 7.x is available from github but there are no further releases or binaries for download.

See different EAP/AS7 discussions.

WildFly continue as the community version and the next EAP will be based on that. Here you will have further releases and it depend on several decisions whether the next release is a minor or major version. So there is no fixed schedule like after Y minor versions a new major version will be released.

Does that make sense to you?

Until now I do not have seen WildFly as a simple renaming of JBoss AS, since even web container has changed

Well it is a rename with it's first release being the next major release, being a major release it can be expected to contain major changes ;-)

If you have a short look to github Releases · wildfly/wildfly · GitHub you see that the repository starts with AS7 releases.

The codebase is exact the same.

OK, thanks, I didn't realize that until now.
