Microsoft has released an update to Windows Subsystem for Linux (WSL). The updated package includes version 4.19.128. The update is available for systems which have WSL enabled.

Windows Subsystem for Linux (WSL) is a feature of Windows 10 that is intended to be helpful for developers, mostly web developers, who can run native Linux daemons and binaries in a familiar environment. No virtual machines, and no remote servers are required when you have the Windows Subsystem for Linux enabled. Developers who prefer Windows 10 over alternative operating systems and over previous Windows versions are probably happy to have this tool in their arsenal. Initially, it supported only a single Linux distro - Ubuntu. Starting in Fall Creators Update, the user is be able to install other distros like the SUSE Linux family from the Microsoft Store.

It looks like the released package is the update for the WSL v1. Unfortunately, there is no change log provided for this patch.

Windows Insiders running Dev channel builds can activate WSL 2, which is a major update to the feature. WSL 2 is a new version of the architecture that powers the Windows Subsystem for Linux to run ELF64 Linux binaries on Windows. This new architecture changes how these Linux binaries interact with Windows and your computer’s hardware, but still provides the same user experience as in WSL 1 (the current widely available version).

WSL 2 uses the latest and greatest in virtualization technology to run its Linux kernel inside of a lightweight utility virtual machine (VM). However, WSL 2 will NOT be a traditional VM experience. When you think of a VM, you probably think of something that is slow to boot up, exists in a very isolated environment, consumes lots of computer resources and requires your time to manage it. WSL 2 does not have these attributes. It will still give the remarkable benefits of WSL 1: High levels of integration between Windows and Linux, extremely fast boot times, small resource footprint, and best of all will require no VM configuration or management.
