The next siegfried release will be out shortly. I have been busy making changes to address two thorny issues: verbose basis and missing results. I have some fixes in place but, when doing large scale testing against big sets of files, I noticed some performance and quality regressions. You can see these regressions on the new develop benchmarks page. There’s also a new benchmarks page to measure siegfried against comparable file format identification tools (at this stage just DROID).
