The diffoscope maintainers are pleased to announce the release of diffoscope
version `87`. This version includes the following changes:

```
[ Juliana Oliveira Rodrigues ]
* comparators:
  + utils:
    - compare: fix comparison between container types.
    - container: add get_path_name() method, aiming at preventing hitting
      OS' max filename length.
  + gzip: replace dest_path generation with self.get_path_name().
  + bzip2: replace dest_path generation with self.get_path_name().
* tests:
  + presenters:
    - skip html_visuals test if 'sng' binary is not available.
  + comparators:
    - test_cointainers: new tests to test cross-container comparisons.
    - add test_containers.py.

[ Chris Lamb ]
* comparators:
  + utils:
    - file: correct reference to path_apparent_size.
  + fonts: loosen matching of file(1)'s output to ensure we correctly also
    match TTF files under file 5.32.
  + binwalk:
    - new comparator to deal with (e.g.) concatenated CPIO archives using
      the new optional python module 'binwalk'.  Closes: #820631
* diffoscope.diff: Correct reference to self.buf.
* debian/rules: run flake8 during the tests, and fail the build in case the
  "underfined name" flake8's check fails.
* tests/comparators:
  + test_cpio: check we identify all CPIO fixtures.
* main:
  + print a debugging message if we are reading diff from stdin.
* presenters:
  + html: use logging.py's lazy argument interpolation.
* debian/control: bump Standards-Version to 4.1.0.
* Code style improvements across all of the codebase.

[ Mattia Rizzolo ]
* debian/changelog: retroactively close a bug in an old changelog entry.
* setup.py: add a check to prevent people from installing diffoscope under
  python < 3.5 (i.e. python2) and give them a usable error message otherwise.
* Code style improvements across all of the codebase.

[ Ximin Luo ]
* comparators:
  +  add a fallback_recognizes() method to work around file(1)'s bug #876316.
     Closes: #875282
  + add a --force-details flag for debugging.
  + deb:
    - if --force-details then don't skip files with identical md5sums either.
* presenters:
  + html:
    - prune all descendants properly.  Closes: #875281
    - don't show pointer-cursor when jquery is disabled.
* config:
  + force-set a value if it must be less than another, and it was not set on
    purpose.  Closes: #875451
* readers: convert bytes to str in the right place.
* diff: use diff_split_lines everywhere.
* difference:
  + in fmap/map_lines, don't forget about self._visuals.
  + also copy self._comment properly, compare self._visuals in equals().
* tests/comparators:
  + test_deb: make test_md5sums less brittle.
