The Claude Code Changelog

Claude Code 2.1.269 brings a dedicated plugin eval CLI for reproducible benchmarking, with scored JSON output and an HTML report to catch regressions before shipping. The episode also covers higher workflow concurrency via CLAUDE_CODE_WORKFLOW_MAX_CONCURRENT_AGENTS and new /output style controls for cleaner remote and headless runs.

We break down a Claude Code bug that caused SessionEnd hooks to be killed after just 1.5 seconds, even when a global timeout was set, leading to truncated teardowns, missing uploads, and corrupted logs. The episode also covers the fix, best practices for per-hook timeouts, and related updates for gateway pricing sync and OpenTelemetry exports.

We break down how Claude Code 2.1.267 helps teams control AI spending with a hard cap on extended thinking across cloud providers, while still letting subagents and custom prompts use lower effort levels when appropriate.

The episode also covers the new system prompt snapshot toggle, giving prompt engineers faster live iteration without restarting sessions.

Claude Code 2.1.265 brings hot-reloading for local plugins, letting you point plugin dir at a parent folder and load or unload multiple tools live without restarting your session. The episode also covers symlink safety checks, clearer truncation notices for large tool logs, and a refreshed workflows UI for debugging nested agent activity.

We break down new safeguards for AI coding agents in auto mode, including out-of-bounds read protection, stricter cloud metadata containment, and safer behavior in headless CI runs. The episode also covers terminal usability upgrades and clearer diagnostics for proxy and policy issues.

Claude Code gets a major workflow upgrade with larger inline output buffers that keep long test failures and stack traces in context, cutting out extra file-read tool calls. The episode also covers the token tradeoffs, smarter test filtering, and a handful of CLI polish improvements like subagent prompt files, Bash-style keybindings, and stronger safety checks.
