Windows Terminal Preview 1.20.10293.0 for Windows 10 and Windows 11

UPDATE 1/31:



Welcome to Windows Terminal Preview 1.20! We've got a pretty small release this time, since we focused mostly on backportable bug fixes (50% of all checkins were backported to 1.19!). We did land some excellent community contributions this time, however, so take a peek at the notes below for more.

Why are there so many assets? How do I choose?​

Please visit our page documenting the different Windows Terminal Distributions!

• The new rendering engine is now enabled by default in all channels (#16277)
• Double-clicking a wrapped word will now select the entire thing. I know, it's 2024. (#16441) (thanks @js324!)

VT and terminal emulation​
