CHANGES IN CUPS V1.5.0 - Documentation updates. - Localization update (STR #3865) - Needed to limit TLS to v1.0 on some versions of Mac OS X. - The snmp backend did not work with some printers. CHANGES IN CUPS V1.5rc1 - Compile fixes (STR #3849, STR #3850) - The scheduler didn't check for empty values for several configuration directives (STR #3861) - ipptool didn't generate valid XML when a test was skipped. - Added additional error checking to the 1284 device ID code (STR #3858) - Fixed some compatibility issues migrating from the old usblp backend to the libusb backend (STR #3860) - Fixed the wake-from-sleep printing behavior on Mac OS X. - The scheduler incorrectly allowed jobs to be held from a terminating state. - The cups-driverd program could crash when a PPD was renamed. - The dnssd backend took too long to discover printers on large or busy networks with the new default timeout used by lpinfo and the web interface.
