Claude Code 2.1.179

Mid-stream connection drops now preserve partial responses instead of showing a raw error, and the spinner no longer gets stuck at "running tool". This release also fixes a WSL2 mouse-wheel scrolling regression from 2.1.172, a sandbox denyRead/allowRead glob over a large directory tree that made the Bash tool description enormous and froze Linux sessions, and the welcome screen stacking multiple promotional banners, alongside improved plugin loading performance in remote sessions.

What changed

Claude Code 2.1.179 shipped on June 16, 2026. It’s a stability-focused release with no new features, cleaning up mid-stream connection drops, remote-session background task display, terminal and platform regressions, and welcome-screen and focus UI bugs. It also improves plugin loading performance in remote sessions.

Key improvements

  • Improved plugin loading performance in remote sessions

    Loading plugins in remote sessions was slow. This release improves plugin loading performance in remote sessions.

Bug fixes

Streaming and sessions

  • Mid-stream connection drops — When a connection dropped mid-response, the partial response received so far was lost, a raw error was shown, and the spinner got stuck at “running tool”. Partial responses are now preserved and the spinner no longer gets stuck.
  • Remote session background tasks appearing stuck as “still running” between turns — Fixed.

Terminal and platform

  • Mouse-wheel scrolling in WSL2 — Mouse-wheel scrolling didn’t work in WSL2 under Windows Terminal and VS Code (a regression in 2.1.172). Fixed.
  • Sandbox denyRead/allowRead glob over a large directory tree — A glob expanded over a large directory tree made the Bash tool description enormous and the session unusable on Linux. Fixed.

UI and focus

  • Feedback survey capturing a single-digit reply as a session rating — The survey treated a single-digit reply typed immediately after a turn completed as a session rating. Fixed.
  • Welcome screen stacking multiple promotional banners — At most one promo now shows per session.
  • Ctrl+O not showing the subagent’s transcript when viewing a subagent — Fixed.
  • Clicking the prompt input not returning focus from the subagent/footer panel — Fixed.

Notes

  • Stability release, no new features — 2.1.179 is made up of bug fixes and a performance improvement, with no new features.
  • 2.1.172 WSL2 regression resolved — The WSL2 mouse-wheel scrolling issue under Windows Terminal and VS Code was a regression introduced in 2.1.172 and is restored in this release. If you hit scrolling problems in that environment, updating resolves them.
  • Check sandbox read globs on Linux — If a denyRead/allowRead glob over a large directory tree was freezing your session, it works correctly after updating.
