JHOVE 1.22 Release Candidate 2 is available today (April 2).
An issue which was noted but isn’t fixed in this release is the handling of the command line parameters. I don’t think that code has changed significantly since I worked on it. It’s so old that it was already there when I took over the project in 2005, so don’t blame me. :) Hopefully version 1.23 will have revamped command line handling using a modern code library.
