title: diffoscope 122 released
author: Chris Lamb <lamby@debian.org>

The diffoscope maintainers are pleased to announce the release of diffoscope
version `122`. This version includes the following changes:

```
[ Chris Lamb ]
* Apply patch from László Böszörményi to update the squashfs test output and
  bump the required version for the test itself. (Closes: #935684)
* Skip calls to unsquashfs when we are not root or fakeroot.
  (Re: reproducible-builds/diffoscope#63)
* Include either standard error or standard output (and not just the latter)
  if/when an external command fails.
* Fix a few unicode/bytes issues:
  - Avoid a possible traceback caused by a str/bytes confusion when handling
    the output of failing external commands.
  - Ensure that all of our artificially-created subprocess.CalledProcessError
    instances have `output` instances that are bytes objects, not str.
* Improve debugging output:
  * Add the containing module name to the (eg.) "Using StaticLibFile for ..."
  * Improve and condense output when creating our Comparator object types.
* Correct a reference to `parser.diff` as `diff` in this context is a Python
  function in the module, not the actual output returned from diff(1).
* Add the "wabt" Debian package to the test dependencies so that we run the
  wasm tests.

[ Mattia Rizzolo ]
* Now that we test-require wabt, expect that its tools to be available during
  autopkgtests.
