# Week 16 · April 13–17, 2026
> Claude Opus 4.7 with the new xhigh effort level, Routines on Claude Code on the web, /ultrareview cloud code review, a /usage breakdown that shows what's driving your limits, and native binaries replacing the bundled JavaScript.
Releases v2.1.105 → v2.1.113
5 features · April 13–17
Claude Opus 4.7
new model
Anthropic's strongest coding model yet is now the default on Max and Team Premium, and available everywhere else from /model. It adds a new xhigh effort level that sits between high and max: best results for most coding and agentic tasks, applied as the default the first time you switch to 4.7. /effort now opens an interactive arrow-key slider when you call it without arguments, so you can dial intelligence against speed without remembering the level names.
Switch model and effort in one go:
```text Claude Code theme={null}
> /model opus
> /effort xhigh
```
Model config: effort levels
Routines
web
Templated cloud agents that fire on a schedule, a GitHub event, or an API call. Define a routine once on Claude Code on the web with a prompt, the repos it can touch, and the connectors it needs, then let PR-opened, release-published, or your own webhook trigger it without your machine running. The trigger picker now covers GitHub events with optional filters and gives every routine a tokened /fire endpoint for external systems.
Create one from the web UI, or scaffold from your terminal:
```text Claude Code theme={null}
> /schedule daily PR review at 9am
```
Routines guide
/usage breakdown
CLI
More visibility into where your Claude Code usage goes. /usage now shows what's driving your limits: parallel sessions, subagents, cache misses, and long context, each with a percentage of your last 24 hours and a tip to optimize it. Press d or w to switch between day and week views.
Run it any time:
```text Claude Code theme={null}
> /usage
```
Commands reference
/ultrareview
v2.1.111
Comprehensive code review in the cloud. Ultrareview fans your branch out across parallel reviewers on Claude Code on the web, runs an adversarial critique pass over each finding, and returns a verified findings report while your terminal stays free. Call it with no arguments to review your current branch, or pass a PR number to fetch and review that PR. The launch dialog now shows a diffstat so you know what's going up before you confirm.
Review the branch you're on:
```text Claude Code theme={null}
> /ultrareview
```
Or point it at a PR:
```text Claude Code theme={null}
> /ultrareview 1234
```
Ultrareview guide
Native binaries
v2.1.113
The claude CLI now spawns a native per-platform binary instead of bundled JavaScript, so the installed claude command no longer invokes Node. The npm package pulls the right binary in through an optional dependency such as @anthropic-ai/claude-code-darwin-arm64, so your install command doesn't change. The standalone installer already shipped this binary; npm now matches it.
Upgrade and check what you're running:
```bash theme={null}
claude update
claude --version
```
Setup guide
Other wins
Auto mode is now available for Max subscribers on Opus 4.7, and the --enable-auto-mode flag is no longer required
Session recap shows a one-line summary of what happened while you were away; run /recap on demand or turn it off from /config
New /tui command and tui setting switch between classic and flicker-free rendering mid-conversation; focus view moved from Ctrl+O to its own /focus command
Push notification tool: with Remote Control connected and "Push when Claude decides" enabled, Claude can ping your phone when it needs you
Plugins can ship background watchers via a top-level monitors manifest key that auto-arms at session start or on skill invoke
"Auto (match terminal)" option in /theme follows your terminal's dark/light mode
/fewer-permission-prompts scans your transcripts for common read-only Bash and MCP calls and proposes an allowlist for .claude/settings.json
Claude can now discover and run built-in commands like /init, /review, and /security-review via the Skill tool
PreCompact hooks can block compaction by exiting with code 2 or returning "decision":"block"
ENABLE\_PROMPT\_CACHING\_1H opts API key, Bedrock, Vertex, and Foundry users into 1-hour prompt cache TTL
sandbox.network.deniedDomains setting carves specific domains out of a broader allowedDomains wildcard
/undo is now an alias for /rewind, and /proactive is an alias for /loop
Hardened Bash permissions: deny rules now match through env/sudo/watch wrappers, and Bash(find:\*) allow rules no longer auto-approve -exec or -delete

# Week 17 · April 20–24, 2026
> /ultrareview opens as a research preview, automatic session recaps when you return to a terminal, custom color themes you can build and ship in plugins, and a redesigned Claude Code on the web.
Releases v2.1.114 → v2.1.119
4 features · April 20–24
/ultrareview
research preview
Now in public research preview. Ultrareview runs a fleet of bug-hunting agents in the cloud against your branch or a PR, and findings land back in the CLI or Desktop automatically. Run it before merging critical changes such as auth or data migrations.
Review the branch you're on:
```text Claude Code theme={null}
> /ultrareview
```
Or point it at a PR:
```text Claude Code theme={null}
> /ultrareview 1234
```
Ultrareview guide
Session recap
CLI
Switch focus away from a session and come back to a one-line recap of what happened while you were gone. Helpful for staying in flow while running several Claude sessions at once.
Generate a recap on demand, or turn the automatic one off from /config:
```text Claude Code theme={null}
> /recap
```
Interactive mode: session recap
Custom themes
v2.1.118
Build and switch between named color themes from /theme, or hand-edit JSON files in \~/.claude/themes/. Each theme picks a base preset and overrides only the tokens you care about. Plugins can ship themes too.
Open the theme picker and create a new one:
```text Claude Code theme={null}
> /theme
```
Terminal config: create a custom theme
Claude Code on the web
web
A new look for claude.ai/code that matches the redesigned desktop app: sessions sidebar, drag-and-drop layout, and a refreshed routines view. Key parts were rebuilt for quicker responses and a more reliable experience.
Claude Code on the web
Other wins
Vim visual mode: press v for character selection or V for line selection in the prompt input, with operators and visual feedback
Hooks can now call MCP tools directly via type: "mcp\_tool", so a hook can hit an already-connected server without spawning a process
/cost and /stats are merged into /usage; the old names still work as typing shortcuts that open the relevant tab
/config changes (theme, editor mode, verbose, and similar) now persist to \~/.claude/settings.json and follow the same project/local/policy precedence as other settings
Forked subagents can be enabled on external builds with CLAUDE\_CODE\_FORK\_SUBAGENT=1: a fork inherits your full conversation context instead of starting fresh
Default effort level for Pro and Max subscribers on Opus 4.6 and Sonnet 4.6 is now high (was medium)
Native macOS and Linux builds replace the Glob and Grep tools with embedded bfs and ugrep available through Bash, for faster searches without a separate tool round-trip
\--from-pr now accepts GitLab merge request, Bitbucket pull request, and GitHub Enterprise PR URLs in addition to github.com
Auto mode: include "$defaults" in autoMode.allow, soft\_deny, or environment to add custom rules alongside the built-in list instead of replacing it
New claude plugin tag command creates release git tags for plugins with version validation
Opus 4.7 sessions now compute against the model's native 1M context window, fixing inflated /context percentages and premature autocompaction
/resume on large sessions is up to 67% faster and now offers to summarize stale, large sessions before re-reading them
