Just today I noticed that the CBGM for Acts has added substemmata to its repertoire. This is really exciting. When I produced the portion of the global stemma for the Catholic Letters in my thesis, Klaus Wachtel had to personally provide me substemmata using software on a very old Mac. And the data were not publicly available. The ability to do this online means that, using my faster approach explained here (pp. 167–168) and here (p. 102), one could probably put together a global stemma for Acts without too much trouble. I should say that I can’t find any documentation on the CBGM site for this new feature. If anyone has more details about it, please let me know.
