It has come to my attention that I messed up on the semantic versioning numbering <https://semver.org/> for the 1.1.0 release and should have bumped the SO number for libcdio and libsio9660.
The details are that in the 1.1.0 release I added a parameter to cdio_list_free() which breaks compatibility. Therefore the release should have been 2.0.0 rather than 1.0.0. And since that changes the libcdio library (and since the libiso9660 library gets new routines the corresponding SO numbers should have been changed. In the process, there are a couple more small bug fixes around memory leaks, And since I have MinSys2 working on Windows there are some MinGW fixes. I'll post a release candidate probably in a couple of days.
