title: diffoscope 163 released
author: Chris Lamb <lamby@debian.org>
---

The diffoscope maintainers are pleased to announce the release of diffoscope
version `163`. This version includes the following changes:

```
[ Chris Lamb ]
* Bug fixes & new features:
  - Normalise "ret" to "retq" in objdump output to support multiple versions
    of obdump(1). (Closes: #976760, reproducible-builds/diffoscope#227)
  - Don't show progress indicators when running zstd(1).
    (Closes: reproducible-builds/diffoscope#226)
  - Move the slightly-confusing behaviour of loading an "existing diff" if a
    single file is passed to diffoscope to the new --load-existing-diff
    command.
* Output improvements:
  - Use pprint.pformat in the JSON comparator to serialise the differences
    from jsondiff to make the output render better.
  - Correct tense in --debug log output.
* Code quality:
  * Don't use an old-style "super" call.
  - Rewrite the filter routine for post-processing output from readelf(1).
  - Update my copyright years.
  - Remove unncessary PEP 263 encoding lines (replaced via PEP 3120).
  - Use "minimal" instead of "basic" as a variable name to match the
    underlying package name.
  - Add comment regarding Java tests for diffoscope contributors who are not
    using Debian. (Re: reproducible-builds/diffoscope!58)
* Debian packaging:
  - Update debian/copyright to match copyright notices in source-tree.
    (Closes: reproducible-builds/diffoscope#224)
  - Ensure the new "diffoscope-minimal" package has a different short
    description from the main "diffoscope" one.

[ Jean-Romain Garnier ]
* Add tests for OpenJDK 14.

[ Conrad Ratschan ]
* Add comparator for "legacy" uboot uImage files.
