The diffoscope maintainers are pleased to announce the release of
version 150 of diffoscope.

diffoscope tries to get to the bottom of what makes files or
directories different. It will recursively unpack archives of many
kinds and transform various binary formats into more human readable
form to compare them. It can compare two tarballs, ISO images, or PDF
just as easily.

Version 150 includes the following changes:

  [ Chris Lamb ]
  * Don't crash when listing entries in archives if they don't have a listed
    size (such as hardlinks in .ISO files).
    (Closes: reproducible-builds/diffoscope#188)
  * Dump PE32+ executables (including EFI applications) using objdump.
    (Closes: reproducible-builds/diffoscope#181)
  * Tidy detection of JSON files due to missing call to File.recognizes that
    checks against the output of file(1) which was also causing us to attempt
    to parse almost every file using json.loads. (Whoops.)
  * Drop accidentally-duplicated copy of the new --diff-mask tests.
  * Logging improvements:
    - Split out formatting of class names into a common method.
    - Clarify that we are generating presenter formats in the opening logs.
  [ Jean-Romain Garnier ]
  * Remove objdjump(1) offsets before instructions to reduce diff noise.
    (Closes: reproducible-builds/diffoscope!57)
