The diffoscope maintainers are pleased to announce the release of diffoscope
version `84`. This version includes the following changes:

```
[ Ximin Luo ]
* comparators:
  + directory:
    - raise warning for getfacl and remove a redundant try-clause.
    - add a --exclude-directory-metadata option.  Closes: #866241
* diff:
  + Restore artificial limit when calculating linediff, to prevent memory
    blow up.  Closes: #865660
* presenters:
  + text:
    - fix recursive header display in the text output, deeply-nested headers
      were not getting indented far enough.
  + add a PartialString class.
  + html:
    - in html-dir mode, put css/icon in separate files to avoid duplication.
    - split index pages up if they get too big.
    - add a size-hint to the diff headers and lazy-load buttons.
    - diffcontrol UI tweaks:
      * don't toggle buttons for diffs that haven't been loaded yet;
      * make the diffcontrol headers clickable.
    - more intuitive "limit" flags, with some backwards-incompatible changes:
      --max-report-size:
        Old: in --html-dir this limited only the parent page
        New: in --html-dir this applies across all pages
      --max-diff-block-lines:
        Old: in --html-dir 4 * this number applied across all pages
        New: in --html-dir this applies across all pages
      --max-page-size:
        New flag
        Applies to the sole --html page, or the top-level --html-dir page
      --max-report-child-size
        Renamed to
      --max-page-size-child:
        No behavioural changes
      --max-diff-block-lines-parent
        Renamed to
      --max-page-diff-block-lines:
        Old: Only applied to the top-level --html-dir page
        New: Applies to the sole --html page or the top-level --html-dir page
* main:
  + temporarily add old flags back for backwards-compatibility.
  + warn if loading a diff but also giving diff-calculation flags.
  + implement proper boolean flags to fix test failure in previous commit.
* tests:
  + handle existing but not importable modules.
    This fixes the tests during the Python 3.6 transition, where some
    modules (like rpm) exists but are not yet rebuilt for 3.6.
  + fix progressbar failure that was exposed by the previous importing fixes.
  + presenters:
    - skip visual test if tools aren't installed.  Closes: #865625
  + comparators
    - sqlite: test for sqlite 3.19.
    - fsimage: move the guestfs cache out of the default /var/tmp/ into a
      "more temporary" directory.

[ Mattia Rizzolo ]
* debian/control: fix Vcs-Git field.

[ Chris Lamb ]
* debian/control: bump Standards-Version to 4.0.0.

[ Daniel Shahaf ]
* Fix markup in the man page synopsis.  Closes: #866577
 Thanks to Niels Thykier for the report.
