Claude Code 2.1.265 Ships a 1 GB Tool-Result Cap and Three Prompt-Cache Reuse Fixes, Then 2.1.266 Reverts a Gateway Regression Hours Later
Released 2026-09-08 at 20:37 UTC, v2.1.265 adds a 1 GB cap on tool results saved to disk with truncation noted in the preview, supports pointing --plugin-dir at a folder of plugins with live add and remove, and fixes three separate causes of broken prompt-cache reuse involving resumed subagents, agent teammates and SubagentStart hook context. It also fixes non-interactive sessions resetting the shell working directory each turn so a cd now persists, and http-configured MCP servers that only speak legacy HTTP+SSE never connecting. v2.1.266 landed 3 hours 18 minutes later to undo a 2.1.265 regression where the undocumented CLAUDE_CODE_USE_GATEWAY variable began forcing Cloud-gateway sign-in on its own and failed every request with "Not signed in to the Cloud gateway."
