PowerFolder 23.3: Content Security Policy and faster login

Version 23.3 arrived three weeks after 23.2 as a service pack. It protects the web portal with a Content Security Policy against cross-site scripting and clickjacking, renews the HARICA certificate of the desktop client and reworks token and session handling for WebDAV. Calculating used storage became faster, which speeds up login; invitations in large folder structures behave more reliably.
