Periodically, the video screen on the Peloton Bike & Tread will say a software update has been downloaded and installed. However, there is typically no screen or message saying what has changed with the update. This prompts the question of how do you find release notes for what changed in the most recent Peloton update.
Unfortunately, there are no official release notes provided. When major new features are released, Peloton will display a special popup promoting the feature. For most updates, no prompt will be provided. Many updates are bug fixes and performance increases.
