Claude Code CLI 2.0.64 adds async subagents – 4 upgrades turn it agentic

Anthropic quietly turned Claude Code from a linear chat helper into a small agent platform today. Version 2.0.64 lands four big upgrades: async subagents, a now‑paused “instant compact” context trim, custom session naming, and a /stats usage view—all from a quick claude update. This is a CLI release, not a new model, but it changes how you can actually work with the thing.

Async subagents are the headline: you can spin off background workers to crawl a monorepo, tail logs, or watch CI while you stay focused on a foreground task, then have the main agent “wake up” when the side jobs finish with a consolidated report. Early users are already wiring this into repo exploration and bash workflows, treating Claude more like a process supervisor than a chat window. Instant compact tried to keep a continuously summarized history so trims felt instant, but Anthropic pulled it within hours for over‑aggressively summarizing live conversations.

The softer touches—session renaming and /stats—matter once you have dozens of long‑running threads. Naming lets teams organize by feature or client instead of timestamps, and stats make it obvious when you’re leaning too hard on expensive models. Taken with this week’s Cursor council and Mistral Vibe 200k context bump, the coding‑agent race is clearly moving from “smart autocomplete” to orchestration, monitoring, and real project hygiene.
