Current changes are:

    • Fixed: Downloading the TLS server certificate from the certificate chain view is now blocked.
  • OS4X Enterprise:
    • New: A new partner option, „Webaccess notice“ is available, which informs Webaccess users as soon as this HTML configuration is populated at a partner’s site.
    • Optimized: The Permission plugin now also allows empty configuration values ​​for group and owner (and does not change them) without the plugin displaying an error.
    • Fixed: Saving recipients is now possible when a non-unique email address is emptied (the „Save“ button becomes active instead of remaining grayed out).
  • OS4X Portal:
    • Updated: All cURL calls have been switched to the latest library version.
  • OS4X admininistrative web interface:
    • Optimized: The „Possible configuration problems“ section checks for the existence and correctness of the Apache module mod_rewrite.

As the latest version of OS4X available, we recommend to update to this version as fast as possible.
