- `httpUpdate` did not reset the socket file descriptor when the TLS
negotiation failed (Apple #5915)
- The `ippeveprinter` tool now automatically uses an available port.
+- The IPP backend now retries Validate-Job requests (OpenPrinting #132)
- Removed support for the (long deprecated and unused) `KeepAliveTimeout`
directive in `cupsd.conf` (Issue #5733)
