Claude Code v2.1.248

Windows terminals are switched out of win32-input-mode on startup

You'll notice
Useful3 Signal2
Windows

On Windows, Claude Code now turns off win32-input-mode so terminals send normal VT input.

What

On Windows, when Claude Code first puts the terminal into raw mode it now writes a sequence disabling win32-input-mode (DEC private mode 9001), alongside the existing bracketed-paste, focus and theme sequences. Terminals that had it on will send normal VT input instead.

Details
  • Platform-limited: only written when the platform check reports windows. No flag.
  • Only the disable sequence is built; there is no enable counterpart in the bundle.
Evidence

WIN32_INPUT_MODE: 9001

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
