Hi Richard,
I guess it's time to tag and release what's in git. (Or is this too outdated and we should just tell people to build off from git? After all, it's mostly bug-fixing. Comments welcome!)
I would say, it's time to make a release. In my understanding - It would be good to upgrade to Autoconf 2.71 and Libtool 2.4.7, since these releases include a large number of fixes. - Then I offer to spend a day or two testing the thing on the current set of platforms, with current compilers (from Linux/arm over Solaris 11 to Android, with g++ 12 and clang 15, etc.) "just tell people to build off from git" increases the installation effort, compared to a release tarball. Distros like Debian also prefer a release tarball, I think? Bruno
