What

The tmux selection prop and its handling are gone from the prompt input and related components.

Details
  • tmuxSelected was threaded through the prompt input, status line and exit-message components; it and the vs === "tmux" derivation are both gone.
  • The case "tmux": branch it fed did nothing but break.
  • Other tmux integrations are untouched: clipboard, session management and iTerm2 -CC detection all remain.
Evidence

tmuxSelected

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