diffoscope is our in-depth and content-aware diff utility that can locate and diagnose reproducibility issues.

  • diffoscope 77 was unblocked by the release team for stretch.
  • Mattia Rizzolo uploaded 77~bpo8+1 to jessie-backports. development is our experiment into how to process, store and distribute .buildinfo files after the Debian archive software has processed them.

Website development

  • Ed Maste made the upcoming FreeBSD release almost 100% reproducible (see above).
  • Holger Levsen added the number of configured and running builder jobs to the performance stats page.
  • Holger Levsen improved the scheduler, so that untested packages and versions are tried sooner.
  • Holger added logging for submitting .buildinfo files to ` and added notification about this failure.
  • Holger also made some minor improvements to the generated HTML.


This week’s edition was written by Chris Lamb, Ed Maste & Levsen and reviewed by a bunch of Reproducible Builds folks on IRC & the mailing lists.
