Windows Terminal Preview 1.17 now out with Mica support and process restart

Windows Terminal became the default command line tool in Windows 11 back in October 2022, which means that Microsoft is more focused than ever on making it a suitable CLI for millions of customers. The company regularly updates Windows Terminal with new functionalities, while maintaining two release branches: Windows Terminal and Windows Terminal Preview. Now, it has released Windows Terminal Preview 1.17 and updated the stable release to version 1.16 too.

Windows Terminal Preview 1.17 includes support for dropdown customization to add folders, separators, and profiles by editing the settings.json file. Additionally, another feature some might like is the ability to restart a process by pressing Enter after it has terminated. Moreover, launch position parameters in the Startup section of the Settings UI can be configured too.

On the aesthetics side, there is support for Mica as a background material in Windows 11 by setting the useMica property to "true" in the settings.json file. Similarly, the Color schemes page has been updated again to be more intuitive. You'll even be able to see a preview of a color scheme before you select it.

Other items from the changelog are quoted below:

  • Other Color Scheme Improvements
    • You can now configure a color scheme (per profile) to apply in System Light theme and System Dark theme
    • You can now configure a color scheme (per profile) to apply in Application theme
  • Virtual Terminal (VT) and Output
    • HUGE shoutout to @j4james for his amazing contributions in the VT space. James worked tirelessly to improve support for VT features, including rewriting how text output is processed in Windows Terminal. Here is a brief summary of the VT contributions that James made for this release:

    • Added support for private options in DSR queries
    • Added support for selective erase operations (DECSED)
    • Added support for the DECRQM escape sequence
    • Added support for the rectangular area operations (DEC*RA)
    • Merged the legacy and extended attributes
    • Rewrote how we handled text embedded in a stream of VT, which closed 8 bugs!
    • Added support for line rendition attributes (DECDHL) over ConPTY
    • Added support for soft fonts over (DECDLD) ConPTY as well
    • Wide characters will no longer cause weird cursor leavings
    • VT reports once again work when DECARM is disabled
    • Thanks again for all your help, James!

    • We now attempt to account for transparent tab backgrounds when calculating the text foreground color
