The 4.4.2 release was produced in parallel with this work, but regardless, the updates were probably too significant to include in what was essentially an emergency bugfix release for Firestorm with specific targeted changes anyway.
Cinder (the video uploader) is one of the Firestorm developers and is just showing a working merge of Qarl's update in Firestorm. That will need to be bundled with probably many other Firestorm fixes and updates in a future release, hopefully coming in the not too distant future.
The current status with respect to SL is here https://jira.secondlife.com/br... although it also indicates Cinder's progress (near the end). All of that will need to be merged with other FS updates first though and packaged into a full release.
