ReRun old diffoscope results using newer diffoscope version
Many diffoscope results on https://verification.f-droid.org/ are generated with old diffoscope version. for example the file:
https://verification.f-droid.org/org.thoughtcrime.securesms_239.html
is generated with diffoscope 77, while the latest version currently is 146
ReRun with newer diffoscope version will probably result in better report (due to improvements to presenters, bug-fixed, new comparators, etc..)
So add option/code to auto-detect reports generated with old diffoscope version & regenerate then using newer version.
