Assuming you are referring to
https://docs.dfhack.org/en/latest/docs/guides/quickfort-user-guide.html, it is the latest - it has "latest" in the URL. This thread and that guide are about the new quickfort script, which is implemented as a DFHack script. It has always been a script, never a plugin (see also the first post of this thread). The guide does reuse some material (but not all) from an older implementation of quickfort, which was an external utility (independent of DFHack) written in Python.
You may be confusing this with
blueprint, which is a plugin that has existed for a while and can be used in combination with quickfort, but it has a different use-case.
it doesn't mention anything about you or your accomplishments
I'm not really sure what you're looking for, but these don't seem like things that belong in the documentation to me (other than possibly mentioning breaking changes, but the guide currently says that any Python quickfort blueprints should work with this script). There are lots of contributors to DFHack, listed on the
authors page, and changes are listed in the
changelog (including some quickfort changes).
