Windows Terminal Preview v1.15.186

It's Summer in the US, which means that it's really hot there's a new Terminal preview release!

Here's what's in it:

Why are there so many packages? How do I choose?

This version of Windows Terminal is distributed in two bundles, one of which works on Windows 10-11 and the other of which only works on Windows 11. The Windows 11 version is much smaller because we no longer need to work around a platform issue related to our dependencies.

If you intend on using Terminal as an unpackaged application--that is, extracting the msix file--we recommend that
you use the Win10 bundle. You will need the Visual C++ runtime
redistributable.

In addition, if you install the packaged version on either Windows 10 or Windows 11, it now depends on the Visual C++
Universal Runtime
Package.

Despite these distributions having different version numbers, they are built from the same code and there is no
functional difference between them.

If you install the Windows 10 version on Windows 11, it will probably automatically upgrade itself to the Windows 11
version. It turns out that it is impossible to have two bundles with the same version number, so it has to be this
way.

More Escape Sequences and expanded VT support

Courtesy of @j4james:

• Applications can now use DECCTR to alter the terminal's color scheme (#13139) (#13227)
• The same applications can now use DECAC to assign a color to the default foreground and background colors, as well as change the tab background color (#13058)
• Other applications can now use DECPS to play a basic sequence of musical notes (#13208)
  • This feature is preview-only until we can make sure the MIDI sound font is available everywhere Stable ships.

Documentation

• building.md and mouseInput.cpp got cleaned up a bit (#13333) (thanks @ofek and @oferze!)
• We added a Gannt chart to the roadmap (#13234)

On the back end...

• @lhecker rewrote how we handle coordinates across the project, paving the way for a longer scrollback history and removing a bunch of sources of assertion failures; if you see anything weird that seems like a coordinate system issue, please file it! (#13025)

Bug Fixes

• We no longer suppress black background or gray foreground for PowerShell (#13352)
  • We have chosen to remove this workaround as newer versions of PowerShell's PSReadline component contain a fix for the issue.
  • This was a compatibility band-aid that was impacting the capabilities of great projects such as Oh My Posh.
  • ❗ If you see unexpected black backgrounds appearing behind text while typing a command in PowerShell, make sure your PSReadline version is up to date. You can update your version of PSReadline by running the command, Update-Module PSReadline.
• The Default Terminal banner is now hidden if you opened a session via default terminal (#13344)
  • AKA: We won't nag you to set Terminal as your default if it's demonstrably the default ;P

• AtlasEngine no longer secretly increases the font size of HTML/RTF copies when the font changes (#13384)
• Keyboard selection is now limited to the scrollable area (#13318)
• The "Open in Terminal" shell extension is now hidden when accessing a non-filesystem path like "Quick Actions" (#13206) (thanks @leejy12!)
• Clearing the screen via cls or Clear-Host won't leave behind an erroneous line of text (#13324) (thanks @j4james!)
• Default Terminal sessions now properly pass focus events when opened (#13247)
• Terminal will now use Unicode 14.0 to determine the width of some Unicode characters (#13292)
