TL;DR

  • Mid-stream connection drops no longer eat your response. Partial output is now preserved when the connection breaks, and the spinner no longer gets stuck at "running tool."

  • WSL2 mouse-wheel scrolling works again in Windows Terminal and VS Code (more below). A regression from 2.1.172 disabled scroll in that environment; update if you have been arrow-keying through output.

  • Linux sandbox glob rules over large directory trees no longer blow up the Bash tool description. If a broad denyRead/allowRead glob was making your session unusable, this is the fix.

New in 2.1.179

2.1.179 (June 17, 2026)

  • Fixed mid-stream connection drops: partial responses are now preserved instead of showing a raw error, and the spinner no longer gets stuck at "running tool"
  • Fixed mouse-wheel scrolling in WSL2 under Windows Terminal and VS Code (regression in 2.1.172)
  • Fixed a sandbox denyRead/allowRead glob over a large directory tree making the Bash tool description enormous and the session unusable on Linux
  • Fixed the feedback survey capturing a single-digit reply as a session rating immediately after a turn completes
  • Fixed the welcome screen stacking multiple promotional banners, at most one promo now shows per session
  • Fixed 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 remote session background tasks appearing stuck as "still running" between turns
  • Improved plugin loading performance in remote sessions

Notes

WSL2 scroll regression

2.1.172 disabled mouse tracking on Windows consoles that don't fully support it. That change inadvertently caught WSL2 sessions running inside Windows Terminal and VS Code, which do support mouse wheel events. The result was six days without scroll in that environment. If you skipped 2.1.172 through 2.1.178 because of this, 2.1.179 is the version to land on.
