@GDAlex,
We have not seen any reported issues for the firmware as of now. The users who have already upgraded have tended to ask questions regarding the function of either the new IoT network or the new VPN Client/Server features.
The Full Patch Notes are available on your product page:
New features:
1. Added VPN server/client features, including Open VPN, L2TP VPN and PPTP VPN.
2. Added the static route function.
3. Added the ability to customize the MTU.
4. Added IOT network function.
Improvements:
1. Optimized the MAC Clone function.
2. Optimized the Client List.
3. Improved system reliability and security.
Notes:
1. Please update your Deco APP to the latest version for the new features.
2. If there are other Deco models in your Deco network, you may miss some new features till other models release updates in the near future.
