Hello, I'd like to report again an issue with the Windows binary packages that is still present with the 1.66.0 release (candidate). The issue is reported to the Boost.Python bug tracker at https://github.com/boostorg/python/issues/129, though I don't think I can address it there. In the Windows binary package the libboost_python3 library is built against (and links with) python2. I can't reproduce this myself when building Boost the normal way, and I don't know who owns the logic for building Windows binary packages. It doesn't seem to have its own repo / issue tracker. The fix might thus affect some piece of code that isn't itself part of the release. But it would be great if someone could look into it soon anyhow. :-) Regards, Stefan -- ...ich hab' noch einen Koffer in Berlin...
