191 - ppdOpen*() incorrectly loaded PPDs with multiple JobPatchFile
192 keywords.
193 - The network backends no longer report the SNMP "offline" or
194 maintenance status bits since they are inconsistently implemented and
195 often unreliable.

201 printer had other reasons associated with it.
202 - cupsSendRequest() did not clear old local certificate auth data.

242 its jobs.
243 - The default BrowseLocalProtocols value was not set properly.
