New version not yet offered by FileHippo

Piriform imforms me that the latest version is 4.18.4844. On following the links to download it I am taken to FileHippo, which states that the latest version is 4.18.4842

Doesn't Piriform have its own site from which downloads may be obtained?

And when will FileHippo catch up?
