Chris Lamb made a large number of changes to diffoscope, our in-depth “diff-on-steroids” utility which helps us diagnose reproducibility issues in packages:
- Ensure Debian substvar generation is deterministic regardless of installed packages. (#908072)
- Fix testsuite under LLVM >= 7.0. (#908074)
- Disable binwalk’s configuration for predictable results, etc. (#903444)

- Don’t print GPG output.
- Ensure we return bytes objections from Command.filter to prevent LLVM tracebacks.
These changes were then uploaded as diffoscope version

- Update the build variation documentation to reflect we’re currently doing fewer kernel variation tests.
