EPiServer.ContentDeliverApi 3.12.0

Enhancement

  • Added support for the ContentAreaItem property. You can GET, CREATE, UPDATE, and PATCH the ContentAreaItem property through Content Management API.

Bug fix

  • HAPI-2846 – Fixed an issue in ErrorsStartupFilter that redirected 4nn responses to the corresponding view /Util/Errors/Error4xx. This caused a problem when the partner challenged a 401 response, the filter caught it and redirected it to the Error401 view (which does not even exist) and other weird behavior.
