As of now, I have not found a public change log of the firmware provided for the Elite Suito (Suito-T) trainer. So I gather the information available here.
Firmware 203 (released around June 2025)
(no noticeable effects)
Firmware 201 (released around August 2024)
As some other users beside me have reported, the device no longer shuts off automatically. If the device is connected, the trainer will stay on and connected indefinitely. This has not been the case in previous versions, where e.g. the connected IPad with Zwift would lose its connection once the Elite trainer shuts down. This has also been reproduced with other Bluetooth devices that are connected to the trainer.
