Whilst D41091 mentioned this bug (and bug 264482), documentation/content/en/books/dev-model/_index.adoc was not changed by related <https://github.com/freebsd/freebsd-doc/commit/4bae0126093f11fdadb37697f072d3b74b94305a>. From <https://docs.freebsd.org/en/books/dev-model/#development-model>: > … the production release, called FreeBSD-STABLE. … Bug 273017 is to review the interpretations of 'production' (and more). <https://docs.freebsd.org/en/books/dev-model/#_footnotedef_7> acknowledged: > … The -STABLE branch is still a development branch, … The development model pictured at <https://docs.freebsd.org/en/books/dev-model/#model-summary> does not picture RELEASE … … and so on. > Copyright © Copyright © 2002-2005 Niklas Saers Re: <https://docs.freebsd.org/en/articles/contributors/#contrib-develalumni> the copyright holder became alumnus in 2006. The 2005 document was representative of a point in time, it's nearly eighteen years old, this bug report is nearly eight years old. Realistically, I don't foresee anyone having the impetus to transform the document into a point of reference that can truly reflect the current model. I respectfully suggesting archiving the document, as historic.
