- Sonata Admin 4.43, Block 5.5, Classification 4.11 (no longer pinned),
  Media 4.20, DoctrineORMAdmin 4.21, Formatter 5.5, Intl 3.3, Translation
  3.7, twig/form/doctrine-extensions 2.x: they all support Symfony 6.4,
  7.3+ and 8.0. StimulusBundle registered (required by Sonata Admin).
- Datepicker form theme: the form-extensions 2 one (ours was an exact copy
  of the form-extensions 1 theme).
- doctrine-extensions 2 has no JsonType: Doctrine's json type is used.
- Filter\Configurator: the Sonata 4 actions (dashboard, search,
  autocomplete, ajax form fields...) replace the Sonata 3 CoreController
  and HelperController. Since the Sonata 4 upgrade, the enabled_filter was
  no longer disabled for them (disabled entities missing in the admin
  autocompletes). ConfiguratorTest added.
- php-http/guzzle6-adapter (13 security advisories) removed: Payum uses
  symfony/http-client (HTTPlug), geocoding uses Psr18Client. psr/log 3.
- lib/ekyna/payum-payzen: psr/log 1-3, no Guzzle requirement.
- /admin/search works again for 3 profiles (baseline updated); still a 500
  for the 5 others, as before the migration.
