The Claude Code Changelog

We break down Claude Code 2.1.277’s enterprise networking fixes, including a new egress-boundary flag that skips local DNS lookups and hands hostname resolution to your forward proxy. We also cover static upstream headers in gateway config, telemetry proxy behavior, streaming gotchas, and a few quality-of-life improvements for worktrees and background tasks.

We break down the latest Claude Code point releases, including the new dynamic boundary for prompt caching that can cut input token costs dramatically, plus practical tips for avoiding cache misses caused by whitespace and line-ending changes.

Also covered: automatic prompt sanitization to strip invisible Unicode injection tricks, smoother plugin marketplace registration, and a handy Auto mode status update in slash status.

Claude Code 2.1.277 tackles prompt injection in multi-agent workflows with structural subagent result framing, making it harder for untrusted text to hijack orchestration. The episode also covers better headless error handling, invisible prompt sanitization, and clearer Grep/Glob diagnostics.

Anthropic’s latest Claude Code update moves safety classification checks to the server, cutting token costs for auto mode unless a proxy strips the required headers and forces a fallback. The episode also covers how to diagnose eligibility with /status, disable server checks with an environment variable, and the new AGENTS.md fallback for repo instructions.
