The diffoscope maintainers are pleased to announce the release of diffoscope
version `89`. This version includes the following changes:

```
[ Mike Hommey ]
* comparators:
  + elf:
    - Add fallbacks to elf code section disassembly.  Closes: #879003
  + utils/libarchive:
    - Extract libarchive members with the file extension.

[ Ximin Luo ]
* Auto-generate manpage using help2man, so it's no longer out-of-date.
* difference:
  + Add a Difference.from_command_exc() to help distinguish excluded
    commands from commands returning an empty diff.
* comparators:
  + utils/command:
    - Replace the feed_stdin() feeder into the simpler stdin() function,
      which provides (if needed) a simple file opject instead of a feeder.
  + utils/container:
    - Add a perform_fuzzy_matching() method (wrapping the already existing
      method) so that comparators can easily override it.
  + deb:
    - Loose matching for .deb archive members, so it's possible to e.g.
    compare deb with different control.tar.{gz,xz}.  Closes: #881937
  + elf:
    - Improve disassembly fallbacks with Difference.from_command_exc().
  + png:
    - Cater for the feed_stdin() removal.
  + zip:
    - Run zipinfo on /dev/stdin instead of a variable path to avoid including
     the temporary file name in the output.  Closes: #879011
    - Cater for the feed_stdin() removal.
* presenters/formats:
  + Allow non-text formats to output an empty diff.
* debian/clean:
  + Remove the egg file when cleaning.

[ Chris Lamb ]
* comparators:
  + utils/file:
    - Handle case where a file to be "fuzzy" matched does not contain enough
      entropy despite being over 512 bytes.  Closes: #882981
  + android:
    - Add support for Android ROM boot.img introspection.  Closes: #884557
  + symlink:
    - Make cleanup of placeholders idempotent.

[ Juliana Oliveira Rodrigues ]
* tests:
  + utils/tools:
    - Add a skip_if_tool_version_is() function.
  + elf:
    - Skip some tests if readelf is version '2.29', where its behaviour
      was accidentally changed to exit with code 1 when it previously
      didn't.  Closes: #877728

[ Holger Levsen ]
* debian/control: Bump Standards-Version to 4.1.2.  No changes required.

[ Mattia Rizzolo ]
* debian/control: Set Rules-Requires-Root: no.
* Bump Debhelper compat version to 11.
