Based on the description of the firmware update Deco M4(EU)_V2_1.5.6_2212291.5.6. of version V2 of the M4:

Modifications and Bug Fixes:
1. Newly added ECO Mode (includes Power Mode, Wi-Fi Schedule, and LED Control) to save energy.
2. Fixed some minor bugs.

and the description of the firmware update Deco M4(EU)_V4_1.1.0 Build 20230112 of version V4 of the M4:

New features:
1. Support for customizing Satellite Deco signal source.
2. Support for customizing Clients connection preference.
3. Support for Reboot Schedule.
4. Support for NO-IP and DynDNS.
5. Support for setting Effective Time and Bandwidth Limit for guest network.
6. Support detection of WAN-side Ethernet cable specifications and prompts for exceptions in the app.
7. Support IPv6 plus and Dual-Stack Lite.
8. Added Smart DHCP switch under Access Point mode.

In my opinion think there is more than ".....however given the current situation in the industry version changes are purely reactionary based on supply, there is no reason to suspect that v3 or v4 is better than v2, it just uses different components to achieve the same result".

Is version V4 of the Deco M4 avaibale in The Netherlands?

Please advise.

Thanks.
