Our Roku OS developer release notes are regularly posted at Release notes.
We’ve just posted a preview of what developer API changes are coming soon with Roku OS 16.0, along with a link to how to join the beta program if you want to test with the new OS before it goes to all your Roku device users,
As a reminder, if you are a beta user, please use the Centercode program to provide feedback, including bug reports. Until we start our “release to all” for an OS version, it is under a Non-Disclosure Agreement (NDA). Your feedback is very valuable for the Roku OS development team, but we need it to be done through non-public channels for us to continue these early releases.
