We already know that HTC has delivered the KitKat ROM for its Google Play edition HTC One, and now the kernel source and framework files from that release have been posted on HTCdev. If you blink, you might miss the beginning of the OTA.

The software version this time around is 3.58.1700.5, and the kernel is still at 3.4.10 for this release. These files are mainly of interest to developer types, but you can still download the framework and kernel if you like. They clock in at 371.7MB and 99.8MB respectively. HTC might have decided to drop these downloads after hearing back from Mountain View about the ROM it submitted. Hopefully that means all is well and the OTA is about to get underway.
