I think this pressure to appease users that purchase new camera models as soon as they are released is compromising the testing of new features and bug fixes, as evidenced by the problems and new bugs that get introduced with each and every update.
A possible solution to alleviate this issue is to provide updates for Camera Raw support and Lens Profiles with their own updates, since these two issues no not normally create problems.
Updates for Bug fixes and New Features can then be released when they have been fully tested and not released prematurely.
As far as I am aware the camera profiles and lens profiles are installed into their own specific folders and are shared by Lightroom and Adobe Camera Raw.
Surely Adobe should be able to store them online and users download the ones they need as they are available and place them in the appropriate folder.
