Release Notes Update - July 3rd, 2024: Kernel Module Support in WSL2

We are very excited kernel module support is now available in WSL2! With this latest kernel update, a large set of loadable modules has been introduced, accompanied by an overall config file update. However, please be aware that when using a custom kernel, the default module support is disabled for now. If you’re using a custom kernel, we recommend you edit your kernel config file to build-in all of the modules that you need.

Thank you for your continued support!
