After the Nintendo Switch and Nintendo Switch 2 consoles received the system update to version 23.5.0, the Nintendo Switch 2 Dock and Pro Controller also received firmware updates with the same version number. Currently, both accessories can be manually updated.
Users can enter System Settings and check for and perform updates separately via the "Console" or "Controller" options. However, the full changelog for the Dock and Pro Controller firmware has not been released, so it is currently unconfirmed whether this update fixes specific issues, improves connection stability, or adds new features.
The console's version 23.5.0 is said to include preparations for a new gift feature. The earlier version 23.0.0, released in early September, added Variable Refresh Rate (VRR) output support for TV mode on the Nintendo Switch 2. The "Nintendo Switch 2 Secrets Exhibition" also updated its VRR slider demo, but these changes have not been confirmed to be directly related to this accessory firmware update.
It is currently confirmed that the Nintendo Switch 2 Dock and Pro Controller are both available for manual update to version 23.5.0. Users whose devices are functioning normally may also wait for Nintendo to release further instructions before learning about the specific changes in this upgrade.
