Claude Code v2.1.265 (Sep 8) lets --plugin-dir point at a folder of plugins with live add/remove detection, caps tool results saved to disk at 1 GB with truncation notices, and fixes several prompt-cache-breaking subagent resume bugs plus a plugin path backslash bypass of the symlink containment check on macOS and Linux. v2.1.266 followed hours later to fix a 2.1.265 regression that forced Cloud-gateway sign-in for LLM-gateway and proxy setups using CLAUDE_CODE_USE_GATEWAY with an API key.

Why it matters

The gateway regression broke every request for proxy-based Claude Code setups, and the plugin security fix closes a sandbox-escape path.

Importance: 2/5

Minor versions with real changes: plugin sandbox fix and a same-day gateway regression fix
