Yes, rsync 2.6.0 has some big improvements in the checksum processing
for large files (which makes them transfer with fewer chances for
mismatched blocks):
* Per-file dynamic block size is now sqrt(file length). The
per-file checksum size is determined according to an algorithm
provided by Donovan Baarda which reduces the probability of rsync
algorithm corrupting data and falling back using the whole md4
checksums. (J.W. Schultz, Donovan Baarda)
