Hi I am abit confused here, have seen a post from someone using 5.4-STABLE how is that possible if 5.4 isnt RELEASE yet, and good news on the bug fix.
When RELENG_5_4 was branched, RELENG_5 went from 5.4-PRERELEASE to 5.4-STABLE to reflect that it is once again open for less-restricted development. As 5.4 will be released via the RELENG_5_4 branch, it is normal and expected to have 5.4-STABLE around before 5.4-RELEASE.
Casey Schaufler (ex-SGI, previously ex-Sun) gave a great talk at a workshop I was at recently relating to closed and open source release processes. One thing he pointed out that I found quite insightful is that what a development organization does is release source code and a build environment. Specifically, they release it to the release engineers, who then release a product, and may iterate some on the source product before turning it into the product. We represent that in the FreeBSD world through a notion of release engineering branches: when the developer team is ready to generate a source product, we generate a branch. It's done with the help of the release engineering team, but at some point the correlation between the source development branch and the releasee engineering branch becomes lower and they are essentially independent.
Casey was careful to point out that what a release engineering team releases may be quite different from the development organization's product -- it may have custom patches, custom build changes, documentation (release notes), logos, and who knows what else.
While there's overlap in these processes, and there's no cut and dry hand-off as a result of some iteration on the release process, I think this is a useful world view, and it explains why branches become -STABLE, etc. The development organization, once its cut its source release to the release engineering team, goes back to doing what it does: building software for its next release. We used to make the handoff synchronous, and we found that caused a lot of heartache. The loosely synchronous model we have now (where people are a bit restrained) appears to work better.
