+ - Removed the unused function write_int_named(), the unused variable
+ io_read_phase, and the rarely used variable io_write_phase. This also
+ elides the confusing 'phase "unknown"' part of one error message.
+
+ - Removed two unused configure checks and two related (also unused)
+ compatibility functions.
+
+ - The xattrs.diff patch received a security fix that prevents a potential
+ buffer overflow in the receive_xattr() code.
