 - `services.monero` now includes the `environmentFile` option for adding secrets to the Monero daemon config.
 
+- The new option [networking.ipips](#opt-networking.ipips) has been added to create IP within IP kind of tunnels (including 4in6, ip6ip6 and ipip).
+  With the existing [networking.sits](#opt-networking.sits) option (6in4), it is now possible to create all combinations of IPv4 and IPv6 encapsulation.
+
+- It is now possible to configure the default source address using the new options [networking.defaultGateway.source](#opt-networking.defaultGateway.source),
+  [networking.defaultGateway6.source](#opt-networking.defaultGateway6.source).
+
+- Potential race conditions in the network setup when using `networking.interfaces` have been fixed by disabling duplicate address detection (DAD)
+  for statically configured IPv6 addresses.

 - `amdgpu` kernel driver overdrive mode can now be enabled by setting [hardware.amdgpu.overdrive.enable](#opt-hardware.amdgpu.overdrive.enable) and customized through [hardware.amdgpu.overdrive.ppfeaturemask](#opt-hardware.amdgpu.overdrive.ppfeaturemask).
   This allows for fine-grained control over the GPU's performance and maybe required by overclocking softwares like Corectrl and Lact. These new options replace old options such as {option}`programs.corectrl.gpuOverclock.enable` and {option}`programs.tuxclocker.enableAMD`.
