If you’re wondering what new features this major version brings, we can tell you that CUPS 2.2 implements support for local IPP Everywhere print queues, along with support for using the http*Connect protocol in Linux-based systems when the CUPS daemon is not running, and an updated database of supported IPP Everywhere media types. Other than the above, CUPS 2.2 improves the IPP backend to correctly validate Transport Layer Security (TLS) credentials, updates the printer-state-message attribute to be cleared after an errorless print job, updates various localizations, makes the CUPS-Add-Modify-Printer and CUPS-Add-Modify-Class operations more informative about failures, and adds support for PPD files whose names are longer than 127 bytes.
