Release Notes for Windows Subsystem for Linux in the Microsoft Store

These release notes are for WSL inside of the Microsoft Store.

Known Issues:

  • Launching Windows Subsystem from Linux from session zero does not currently work (for example from an ssh connection).
  • The Linux icon in Windows Explorer will only appear if you have the Windows Subsystem for Linux Optional Component installed.

0.48.2.0

  • Fix issue preventing Windows binaries from launching from inside the Linux filesystem [GH 7521].
  • Fix error handling condition for wsl --mount --bare.
  • Add localized strings for the following locales: cs-CZ;da-DK;de-DE;en-GB;en-US;es-ES;fi-FI;fr-FR;hu-HU;it-IT;ja-JP;ko-KR;nb-NO;nl-NL;pl-PL;pt-BR;pt-PT;ru-RU;sv-SE;tr-TR;zh-CN;zh-TW. We are investigating an issue where some strings are not being properly localized.
  • Fix for /etc/fstab mounts so they are present in both elevated and non-elevated mount namespaces.
  • Added a 5 second retry timeout to wsl.exe --mount operations.
  • Simplify vm idle termination logic
  • Update wsl.exe --mount to support passing options before the disk name for example: wsl.exe --mount --vhd foo.vhdx
  • Allow individual distros to opt-out of GUI applications via a new /etc/wsl.conf setting:
    [general]
    guiApplications=false
    
  • Ensure requested amount of swap size is available to Linux (previously was a page smaller than requested due to mkswap overhead).

0.47.1.0

  • WSLg is now bundled as part of the WSL app!
    • Update Microsoft.WSLg to version 1.0.29
    • Switch to msrdc.exe for WSLg

    • Allow environment variables used by WSLG to be overridden by WSLENV
  • New wsl.exe –mount features!
    • Add mount --vhd to make mounting VHD files easier.
    • Implement filesystem detection for wsl.exe --mount. This change implements filesystem type detection if no --type is specified when using wsl.exe --mount.
    • Add --name feature to wsl.exe --mount. This change adds support for optionally naming a mountpoint when mounting a disk through WSL.
  • Update Linux kernel to 5.10.60.1
    • Enable additional USB kernel configuration options for interacting with an Arduino over USB
    • Update to upstream stable kernel release 5.10.60
    • Enable virtio-pmem with support for PCI BAR-relative addresses
    • Enable vPCI support under Hyper-V for ARM64
    • Enable io_uring support
    • Enable USB over IP support
    • Enable paravirtualized spinlock support for x86_64
    • Refresh dxgkrnl driver to pick up bug fixes and code cleanups
    • Enable NFS client support for NFSv4.1* Improve the error message when 9p or fstab mounts fail
  • Fix \\wsl$\ and \\wsl.localhost\ issues on ARM64.
  • Switch to mkfs.ext4 instead of pre-formatted ext4 VHD.
  • Switch to using mkswap and swapon instead of custom swap file logic. [GH 5476]
  • Add logic to dynamically update the MTU of the NAT network
  • Fix for /etc/wsl.conf generateResolvConf not working as expected [GH 6977]
  • Added progress indicator helper function used to show a Please Wait message with animated dots on the conversion process to show users that WSL is still running.
  • Switch wslhost.exe to a win32 app.
  • Switch wsl.exe --install to not require the --distribution argument. This change switches wsl.exe --install to not require the --distribution argument but maintains support to avoid breaking existing scripts.
  • Add wsl.exe --version command
  • Add Windows version to wsl.exe --status and wsl.exe --version
  • Cleanup wsl.exe invalid argument handling to make syntax errors easier to self-diagnose.
  • If the app is launched via the tile, prompt the user for input before closing the console window.
  • Add error message dialog for wslg.exe
  • Simplify print for unsupported command line arguments.
  • Print a better error message if the user runs wsl.exe --install when WSL is already installed
  • Add special error codes for custom kernel not present, and custom kernel not supported (ARM64)
  • Update wsl.exe --update to launch the store page.
  • Improved stability and performance of localhost relay.
  • Additional performance and stability improvements.
