Phil, Looking at the Sourceforge activity: https://sourceforge.net/p/xetex/code/commit_browser the latest source is v0.99999 which was prepared in February 2018 for TeX Live 2018.
The changes seem to be bugfixes and seem to mostly originate from Japanese contributors. They are summarized at https://sourceforge.net/p/xetex/code/ci/master/tree/source/texk/web2c/xetexdir/NEWS and there have been a few minor changes after that. It looks like "features" were last added in 2016. It seems like XeTeX does not have very active development or maintenance, but there is some. I would encourage you to file a feature request at https://sourceforge.net/p/xetex/feature-requests/ If it's recorded, it's possible that at some point someone will address it.

I ask because, once again, I came up against a fundamental limitation of XeTeX yesterday — the fact that a font can be defined to be of a specific colour, but the colour model is restricted to RGB. Given that (IMHO), the vast majority of XeTeX output is intended for print rather than for on-screen display, would it be possible to add support for additional colour models (and specifically for CMYK) in a future instantiation of the \font primitive ? -- <Signature> Philip Taylor -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
