The main change in the past year has been the psy optimizations that were added; before the psy optimizations, x264 was roughly on par with Mainconcept, one of the better commercial encoders. The psy optimizations--adaptive quantization and psy-RD (both on by default)--put x264 way over the top. Recently, the new MB-tree algorithm (also on by default) has boosted quality quite a bit as well. The main catch with psy optimizations is that they're nearly impossible to measure mathematically, and in fact, unless you disable them, they will make the "mathematical" measures of quality (mean squared error/PSNR) much worse.
It's always nice when free software solutions trash the commercial alternatives.
