9September 7–11, 2026

911**`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.
1012
1113Also 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.

1721**Claude Fable 5.1**: available in Claude Code with a 1M-token context window.
1822
1923Also 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.

29August 24–28, 2026
30
2531**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.
2632
2733Also 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.

3238
39August 17–21, 2026
40
3341**`/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.
3442
3543Also 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.

49August 10–14, 2026
50
4151**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.
4252
4353Also 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.

4858
59August 3–7, 2026
60
4961**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.
5062
5163Also 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.

79July 13–17, 2026
80
6581**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.
6682
6783Also 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.

7391**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.
7492
7593Also 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.

109June 22–26, 2026
110
89111**`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`.

91113Also 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.
