9The 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](https://code.claude.com/docs/en/changelog.md).
10
11**Week 37**
12
13September 7–11, 2026
14
15**`claude plugin eval`**: run your plugin against a suite of test cases, score the results, and compare against a no-plugin baseline. `claude plugin eval init` drafts the cases and graders for you.
16
17Also this week: pop any **Claude Code Desktop pane** out into its own window and dock it back later; the **`maxEffortLevel`** setting caps the effort level on every provider; and a page that **WebFetch** hasn't finished downloading within five minutes fails instead of hanging.

21**Week 36**
22
23August 31 – September 4, 2026
24
25**Claude Fable 5.1**: available in Claude Code with a 1M-token context window.
26
27Also this week: on Pro and Max plans, **computer use in the Desktop app** works in the background on macOS while you keep working; in fullscreen rendering, **`/diff`** opens a live panel beside the conversation that refreshes as Claude edits; and **`/skill-doctor`** shows what each of your skills costs in context and how often it gets used.

31**Week 35**
32
33August 24–28, 2026
34
35**Resume terminal sessions in the Desktop app**: type `/resume` in the Claude Code Desktop prompt box to pick up any session you started from the CLI, with the full conversation and context intact.
36
37Also this week: **Claude-drafted feedback** has Claude write up a feedback report when something goes wrong in a session, which you review and send from `/feedback`; **`--restricted`** starts a session without the command-running tools or your user and project settings, for evaluation harnesses on shared machines; and the **`modelPicker`** setting controls which models the `/model` picker lists.

40
41**Week 34**
42
43August 17–21, 2026
44
45**`/design`**: a research preview that brings Claude Design's artboard workflow into the CLI and Claude Code Desktop, built on artifacts, so Claude drafts editable artboards for your UI and implements the one you pick.
46
47Also this week: the built-in **Concise output style** makes Claude lead with the result and skip preamble; any machine running `claude remote-control` shows up as a **device card** on your phone so you can start a session on it from the Code tab; and **`ANTHROPIC_DEFAULT_MODEL`** sets the model new sessions start on.

50
51**Week 33**
52
53August 10–14, 2026
54
55**Auto-continue after a usage limit on Desktop**: when you hit your session limit in Claude Code Desktop, check **Auto-continue when limits reset** on the limit card and the app retries the interrupted turn once the limit resets.
56
57Also this week: **fork mode** is on by default in interactive sessions, so Claude can delegate a side task to a subagent that inherits the full conversation; **GitLab** merge request URLs work with `--worktree` and the `claude agents` view, and marketplaces clone bare `gitlab.com` URLs; and typing **`@`** in the prompt mentions another Claude session by name.

60
61**Week 32**
62
63August 3–7, 2026
64
65**Cross-session messaging**: on macOS and Linux, your Claude Code sessions can now message each other, so Claude passes a finding or a decision from one session to another instead of you re-explaining it.
66
67Also this week: **self-hosted environments** run Claude Code cloud sessions on infrastructure your organization operates, in public beta on Team and Enterprise plans; **auto mode** becomes the default permission mode for new sessions on Pro, Max, and Team plans starting August 14; and the **VS Code extension** gets Focus view.

71**Week 30**
72
73July 20–24, 2026
74
75**Claude Opus 5**: the new default Opus model in Claude Code, with a 1M-token context window and fast mode at \$10/\$50 per MTok.
76
77Also this week: **Claude Code Desktop** opens an iOS Simulator pane in public beta so Claude can run your app and tap through it while you watch; the **Claude Security plugin** runs a multi-agent vulnerability scan of your codebase and turns the findings you pick into patches you apply yourself; and **`/code-review`** runs as a background subagent.

80
81**Week 29**
82
83July 13–17, 2026
84
85**Artifacts call your MCP connectors**: a published artifact can pull live data and take actions through each viewer's own MCP connectors when they open the page, and this week also adds public sharing links, editor roles on Team and Enterprise, and artifacts created from Claude Tag sessions.
86
87Also this week: **screen reader mode** replaces the visual terminal interface with plain, linear text for screen readers such as VoiceOver and NVDA; **`/fork`** copies your conversation into a new background session while you keep working; and **auto mode** no longer needs an opt-in variable on Amazon Bedrock, Google Cloud's Agent Platform, and Microsoft Foundry.

91**Week 28**
92
93July 6–10, 2026
94
95**In-app browser on Desktop**: Claude Code on desktop gets a built-in browser, so Claude can pull up docs, designs, or any other site and interact with pages the same way it does with your local dev server previews.
96
97Also this week: **`/doctor`** is a full setup checkup that diagnoses issues and can fix them, with `/checkup` as its alias; **auto mode** blocks transcript tampering and asks before `rm -rf` on unresolved variables; and **agent view rows** show a colored state word and a classifier-written headline.

102
103June 29 – July 3, 2026
104
105**Claude Sonnet 5**: the new default model for Pro, Team Standard, and Enterprise subscription seats, with top-tier coding and tool use at Sonnet pricing, a native 1M-token context window, and adaptive thinking on by default.
106
107Also this week: **Claude in Chrome** is generally available on all direct Anthropic plans; **subagents run in the background by default** so Claude keeps working while they run; **Claude Desktop on Linux** lands in beta on Ubuntu and Debian; and **`/radio`** tunes into Claude FM lo-fi radio.

111**Week 26**
112
113June 22–26, 2026
114
115**`claude mcp login`**: authenticate a configured MCP server from your shell instead of the interactive `/mcp` menu, and clear its stored credentials later with `claude mcp logout`.
116
117Also this week: **shell mode responds to command output** (`! npm test` gets an explanation without a second prompt); **`/rewind`** can resume a conversation from before `/clear` was run; and **background subagents** now surface permission prompts in the main session instead of auto-denying.
118

120
121**Week 25**
122
123June 15–19, 2026
124
125**Artifacts**: turn a session's output into a live, shareable page on claude.ai that updates in place as the session works, now in beta on Team and Enterprise plans.
126
127Also this week: **deny and ask rules match tool parameters** with `Tool(param:value)`, for example `Agent(model:opus)`; **`/config key=value`** sets any setting from the prompt, in `-p` mode, and from Remote Control; and **auto mode blocks destructive git commands** when you didn't ask to discard local work.

172
173May 11–15, 2026

192
193April 27 – May 1, 2026

201**Week 17**
202
203April 20–24, 2026
204
205**`/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.
206
207Also 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.

212
213April 13–17, 2026
214
215**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.
216
217Also this week: **Routines** on Claude Code on the web fire templated cloud agents from a schedule, GitHub event, or API call; **mobile push notifications** ping your phone when a long task finishes or Claude needs you; `/usage` shows what's driving your limits; and the CLI moves to native binaries.

220
221**Week 15**
222
223April 6–10, 2026
224
225**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.
226
227Also 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.

231**Week 14**
232
233March 30 – April 3, 2026
234
235**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.
236
237Also 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`.

240
241**Week 13**
242
243March 23–27, 2026
244
245**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`.
246
247Also 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.
