Join this channel to get access to perks: https://www.youtube.com/channel/@aicodeking/join In this video, I'll go through the Claude Code updates from the last month, 23 releases from version 2.1.293 to 2.1.319, and show you what each one actually does. I'll start with the new Claude Haiku 5.5 model, then the ultrathink and subagent effort fixes, idle compaction and the new limit warnings, and the big upgrades to background work. After that, I'll cover the new permission and auto mode settings, a set of smaller terminal improvements, and everything that changed in the desktop app's Code tab, including Claude Duet and the Claude Design closing notice. For each update, I'll also show you how PandaCode handles the same thing, and I'll finish with the limitations of both before giving you my verdict. -- Key Takeaways: 🚀 Claude Code shipped 23 releases this month, going from version 2.1.293 to 2.1.319, plus a lot of changes to the desktop app's Code tab. 💸 Claude Haiku 5.5 came out on October 7th with a 1 million token context window at 10 cents per million input tokens and 50 cents per million output tokens. 🧠 Typing ultrathink now runs that turn at extra high effort on Opus 5.5, Sonnet 5.5, Haiku 5.5 and Fable 5.1, and subagents on another model now use that model's saved effort. 📊 Idle compaction summarizes conversations over 200 thousand tokens after about 54 minutes idle, just before the one-hour prompt cache expires, and you can turn it off in slash config. ⚠️ Pro and Max users now get a warning before resuming an old conversation that would use a noticeable part of their 5 hour limit, and slash usage flags things that quietly burn tokens. 🔀 MCP task tool calls now move to the background right away, and slash tasks lets you reopen and message a finished subagent even after a restart. ✅ The new slash auto mode setup command, deny instead of prompting setting, and a block on writes outside your working folders make long unattended runs safer. 💻 Terminal upgrades include Program Status Protocol, click to send queued messages, the Vim percent motion, and more powerful mods. ⚡ The desktop Code tab got idle compaction, background and fork subagents, a findings card for slash code review, and a bunch of annoying bug fixes. 🎯 Verdict: none of these upgrades are flashy on their own, but together they make long Claude Code sessions cheaper and a lot less annoying, and PandaCode adds multi-agent work on top.

Your idea can be anything. At our last workshops, people built plant-based nutrition businesses, a way to measure planetary resilience, crochet headwear and a way to connect lonely people living in the same building. This fourth workshop is a full day at KOKO with Nick Sarafa, learning to build with Claude Code. Bring the thing you keep meaning to start. We’ll bring the pizza.
