This *type* of discussion has been had before, in other projects, so thank you for those links. As far as I know, there's no Roadmap defined for what the Plugin will support, and I want that in place. "adrian(a)jboss.org" wrote : you shouldn't be writing the deployers | in the ejb3 plugin project(s). Instead the deployers should be in JBossAS and they should delegate to a stable spi within EJB3 I didn't have any intent of placing the deployers (AS integration points) back into the EJB3 codebase. It's because they *used* to be there (which was incorrect and therefore changed last week) that Beta4 is no longer a valid target for the Plugin. So a multiversion plugin is dependent on a frozen SPI. Until that's written down somewhere, I can't deliver a single Installer to upgrade EJB3 releases across a variety of AS bases.
