* [#3625] Fixed crashes during StUF response parsing when certain ``nil`` values are
  present.
* Updated CSP ``frame-ancestors`` directive to be consistent with the ``X-Frame-Options``
  configuration.
* [#3605] Fixed unintended number localization in StUF/SOAP messages.
* [#3613] Fixed submission resume flow not sending the user through the authentication
  flow again when they authenticated for forms that have optional authentication. This
  unfortunately resulted in hashed BSNs being sent to registration backends, which we
  can not recover/translate back to the plain-text values.
* [#3647] Fixed a backend (logic check) crash when non-parsable time, date or datetime
  values are passed. The values are now ignored as if nothing was submitted.
