This definition is, as you point out, largely lifted from JEP 12. Aside from wording changes, here are some key differences: * JEP 12 assumes that a feature should be finished within two releases. I think for JavaFX, being just a framework and not a programming language, it is sensible to assume that we can finish features in the next release; that is, a preview feature that is introduced in JavaFX N should be finished in N+1. * JEP 12 says that a preview feature should be at least 95% "done". I think we can be a little bit more risk-tolerant here, which is why I lowered this number to 90% "done". The general idea is that preview features in JavaFX should be faster and accept a little bit more risk than preview features in the JDK. ------------- PR Review Comment: https://git.openjdk.org/jfx/pull/1359#discussion_r1941716692
