Claude Code Just Got 4 Huge Upgrades — Here's What Each One Actually Does

I've been using Claude Code for a while now, and most updates are incremental — a quality-of-life tweak here, a small model improvement there. But the v2.1.71 drop (March 2026) genuinely changed how I think about what Claude Code is. Four features landed at once. Together they shift Claude Code from "chat that helps me code" to something closer to an autonomous system that keeps working while I'm not. Let me walk through each one so you know exactly when and why to use it. 🧠 Feature 1: /loop — Recurring Prompts Inside Your Session Before this, if you wanted Claude to check something repeatedly, you had to keep coming back, typing the same prompt, waiting, coming back again. Tedious. /loop changes that. You give it a task in plain English and it sets up a cron job inside your current session that fires automatically. # Check inbox every 10 minutes — no babysitting needed /loop every 10 minutes check my inbox for important emails # Daily content repurposing — runs the skill automaticall
