| Claude Code v2.1.259 fixes two multi-session bugs — running several concurrent sessions no longer silently reverts another session's ~/.claude.json changes, and Stop now actually halts background agents in remote-control sessions.

The spec change we led with yesterday, landing in the product a day later. | · Anthropic · claude.com |
