DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.251

Background terminals now also kill the REPL session behind them

You'll notice

Background Tasks

Killing a background terminal now also ends the REPL process behind it.

What

A background pseudo-terminal now looks up and remembers the session id of the REPL process it belongs to when it first connects, and signals that session too when the terminal is killed or exits, so stray processes are less likely to survive.

Details
  • The session id is surfaced through an onRepl callback on the background-pty client.
  • Skipped on Windows.
Evidence

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