Claude Code 2.1.191: /rewind Can Now Jump Back Past /clear

Copy article as Markdown

The releases up to 2.1.191 add something many of us have wanted for a long time: /rewind can now roll back to before an accidental /clear. There's also sturdier streaming and a fix that finally keeps stopped background agents stopped.

If you use Claude Code daily, you know the sinking feeling after an accidental /clear: the whole context gone, the session effectively reset. That’s exactly what the release wave up to 2.1.191 addresses — with a fix I was genuinely happy to see.

/rewind now jumps back past /clear

Until now, /clear was a one-way street. From now on, /rewind can roll a conversation back to the point before you ran /clear. It sounds minor, but it rescues the exact situation where you’d otherwise start over — one wrong keystroke, and the context you carefully built up isn’t lost anymore, just one rewind away.

For the record: versions 2.1.188 and 2.1.189 never made it to npm, and 2.1.190 only carried the usual “Bug fixes and reliability improvements.” So the interesting stuff lives in 2.1.191.

Streaming that no longer stutters

The second big chunk is stability fixes around streaming:

  • When scrolling back through earlier output, the view used to jump back to the bottom while a response was still streaming. Fixed.
  • If the connection drops mid-stream, the partial response you already received is now preserved instead of being replaced by a raw error. The spinner no longer gets stuck on “running tool” either.
  • Background agents you stopped from the tasks panel are now actually stopped — no more zombies coming back to life.

There are smaller but welcome fixes too: /voice now explains why it’s disabled when an organization blocks it by policy, instead of just showing a generic “not available.” The /login URL no longer wraps into something unusable in Windows Terminal, and Cmd+click on links works again in Ghostty’s fullscreen over SSH/tmux.

Noticeably lighter under the hood

Performance comes on top: roughly 37% less CPU usage during streaming, and the memory growth in long sessions — caused by the terminal output cache — has been reined in. For marathon sessions where you leave Claude Code running for hours, that genuinely matters.

My take

These aren’t headline features — they’re friction removal. But it’s exactly these unassuming releases that make a tool grow up. /rewind past /clear is a classic “why didn’t it always work this way?” feature — and once you’ve used it, you never want to give it back. Anthropic keeps polishing Claude Code right where power users bump into rough edges every day. I like that.
