Dona Sarkar, the new owner of the Windows Insider Big Red Release Button has just announced the release of Windows 10 Anniversary Update Insiders Build 14361 to the fast-ring: Start your download engines - this is a release filled with huge improvements, too numerous to list here, but which are nicely summarized in the release email.
Also included in this release are a large number of very important improvements to Bash on Ubuntu on Windows and the Windows Subsystem for Linux (WSL). The WSL team have published a list of the most notable changes to this (and previous) builds on the WSL release notes page.
One of the most exciting new features in this build is support in WSL for Pseudo Terminals (PTY) which finally enables Tmux support! What is Tmux and why should you care? Read more about this feature including a getting started tutorial on this accompanying post.
As we near the end of our engineering period for Windows 10 Anniversary Updates, we encourage everyone interested in helping improve Bash on Ubuntu on Windows to install this and subsequent builds, and to file any new issues on our GitHub Issues repo: We greatly appreciate your help testing and validating Bash on Ubuntu on Windows and WSL - the issues you've reported have resulted in many important and meaningful fixes making it into the product, making this first release better for all.
