-Improved functional sequence for Contrast AF and improved total speed until in focus.
Hence the term 'silent update'. Proven or not, Pentax (maybe other brands too) are regarded to include unannounced fixes to f/w releases. This allows them not to officially acknowledge any problems.
Yes the link is in the front page, but for a few days, that also showed a 'page not found error'.
I'm not saying there was a silent update, or there is a conspiracy here. I'm just saying it may be a possibility.
As a K-r owner myself, I also want this issue resolved. And the seemingly positive feedback on the K-5 update is really an inspiring thing
