+ * Device numbers are now sent as separate major/minor values
+ with 32-bit accuracy for each one (protocol 28). Previously
+ hard-link device data was sent as a single 64-bit number, and
+ copied devices were sent as a single 32-bit number. This will
+ make inter-operation of 64-bit binaries more compatible with
+ their 32-bit brethren. Note that optimizations in the binary
+ protocol often sends the device data using fewer bytes than
+ before, even though more precision is now available.

+ * Some cleanup of the exclude/include structures and its code
+ made things clearer, simpler, and more efficient.
