Microsoft, during the Build developer conference in May, made the groundbreaking announcement that the Windows Subsystem for Linux (WSL) would embrace open-source principles. Today, the WSL 2.6 version is officially launched, marking its debut as the pioneering release under Microsoft's open-source initiative. Although the source code for WSL 2 has been publicly accessible since the Build 2025 conference, this marks the first occasion where new feature updates are introduced in an open-source format.
