• PkgVersion warns when a file declares a perl v5.38 class, which it
  cannot version because PPI cannot parse class syntax (github #742)
  
• AutoPrereqs no longer lists the dist's own main module as a prereq
  when main_module lives outside lib/ (github #672, rt.cpan.org #55680)
  
• add a security policy in SECURITY.md (github #736)
  
• Dist::Zilla::Tester now uses autodie correctly, so in rare cases you
  might get an exception where previously something failed silently
  
• the test suite no longer leaves a tmp directory behind
  
• copyright_year may now be any string, not just an integer, and
  the string $this_year in it is replaced with the current year, so
  "2008 - $this_year" works (thanks, Dave Rolsky; github #578)
  
• the copyright_year in the %Rights stash is now a Str, not an Int
