Microsoft has rolled back the kernel for the Windows Subsystem for Linux (WSL) from version 6.6.36.3 to 5.15.153.1-2 while debugging issues. This rollback is a precautionary measure to address potential problems linked to iptables, which is important for Docker. The changelog includes fixes for a race condition when stopping a WSL2 distribution, a format attribute for printf errors, segmentation faults during initialization, added Hyper-V firewall rules for inbound mDNS traffic, an update to the Windows SDK to version 26100, and a refresh of the Microsoft.Windows.ImplementationLibrary to version 1.0.240803.1. Users on the stable release of WSL2 are not experiencing issues, but those on the pre-release version may need to download the latest release for a better experience.
