This release improves the build system to check the version of readline and only build with versions that work. This should fix compilation errors on macOS where its ancient libedit’s readline support is incomplete.
Copyright headers have now been added to all source files.
The magic files for file(1) have been removed. The magic in file(1) has been updated upstream, and should be available in file 5.46 and later.
Finally, the HISTORY file is updated to account for the last 15 or so years,
and etc/psidump.1 has been edited to remove references to its original
upstream: it’s long been part of plptools as far as plptools is concerned.
