What's new

A weekly digest of notable Claude Code features, with code snippets, demos, and context on why they matter.

The weekly dev digest highlights the features most likely to change how you work. Each entry includes runnable code, a short demo, and a link to the full docs. For every bug fix and minor improvement, see the changelog.

<Update label="Week 17" description="April 20–24, 2026" tags={["v2.1.114–v2.1.119"]}> /ultrareview opens as a public research preview: a fleet of bug-hunting agents runs in the cloud and findings land back in your CLI or Desktop automatically.

Also this week: session recap shows you what happened while a terminal was unfocused; custom themes let you build and ship color palettes from /theme or a plugin; and Claude Code on the web gets a redesign with a new sessions sidebar and drag-and-drop layout.

<Update label="Week 16" description="April 13–17, 2026" tags={["v2.1.105–v2.1.113"]}> Claude Opus 4.7 lands as the new default on Max and Team Premium, with a new xhigh effort level that's the recommended setting for most coding work and an interactive /effort slider to dial it in.

Also this week: Routines on Claude Code on the web fire templated cloud agents from a schedule, GitHub event, or API call; /ultrareview runs parallel multi-agent code review in the cloud; /usage shows what's driving your limits; and the CLI moves to native binaries.

<Update label="Week 15" description="April 6–10, 2026" tags={["v2.1.92–v2.1.101"]}> Ultraplan enters early preview: draft a plan in the cloud from your CLI, review and comment on it in a web editor, then run it remotely or pull it back local. The first run now auto-creates a cloud environment for you.

Also this week: the Monitor tool streams background events into the conversation so Claude can tail logs and react live, /loop self-paces when you omit the interval, /team-onboarding packages your setup into a replayable guide, and /autofix-pr turns on PR auto-fix from your terminal.

<Update label="Week 14" description="March 30 – April 3, 2026" tags={["v2.1.86–v2.1.91"]}> Computer use comes to the CLI in research preview: Claude can open native apps, click through UI, and verify changes from your terminal. Best for closing the loop on things only a GUI can verify.

Also this week: /powerup interactive lessons, flicker-free alt-screen rendering, a per-tool MCP result-size override up to 500K, and plugin executables on the Bash tool's PATH.

<Update label="Week 13" description="March 23–27, 2026" tags={["v2.1.83–v2.1.85"]}> Auto mode lands in research preview: a classifier handles your permission prompts so safe actions run without interruption and risky ones get blocked. The middle ground between approving everything and --dangerously-skip-permissions.

Also this week: computer use in the Desktop app, PR auto-fix on Web, transcript search with /, a native PowerShell tool for Windows, and conditional if hooks.
