Is there a location where I can go to see OS version and build release notes?
Roku doesn't supply that information.
From the Roku blog, https://www.roku.com/blog/roku-os-10-5, there is a link to release notes.

Thanks, but I was looking for something a little more detailed. Example: I am on 10.5.1 build 4049-CU. I’m interested not only in what features the added with each release but also what fixes they deployed.
