19 <p className="digest-feature-lede">`--plugin-dir` now accepts a <code>.zip</code> plugin archive in addition to a directory, and the new `--plugin-url` flag fetches a plugin archive from a URL for the current session. Useful for trying a plugin before adding it to a marketplace, or for shipping internal plugins from an artifact store.</p>

36 <p className="digest-feature-lede"><code>Ctrl+R</code> reverse-search now defaults to all prompts across every project, restoring the behavior from before v2.1.124. Press <code>Ctrl+S</code> while searching to narrow back to the current project or session. Handy when you remember a command you ran in another repo last week and don't want to go digging for it.</p>

44 <div className="digest-wins-grid">

45 <div>New <code>worktree.baseRef</code> setting (<code>fresh</code> | <code>head</code>) controls whether <code>--worktree</code>, the <code>EnterWorktree</code> tool, and agent-isolation worktrees branch from the remote default branch or local <code>HEAD</code>; the default <code>fresh</code> keeps unpushed commits out of new worktrees</div>

46 <div>New <code>settings.autoMode.hard\_deny</code> rules block matching actions unconditionally in auto mode, regardless of allow exceptions, for actions that should never run automatically even when broader allow rules apply</div>

47 <div>Hooks now receive the active effort level via the `effort.level` JSON input field and the `$CLAUDE_EFFORT` environment variable, and Bash tool commands can read <code>\$CLAUDE\_EFFORT</code></div>

48 <div><code>CLAUDE\_CODE\_DISABLE\_ALTERNATE\_SCREEN=1</code> opts out of the fullscreen alternate-screen renderer and keeps the conversation in the terminal's native scrollback</div>

49 <div><code>CLAUDE\_CODE\_PACKAGE\_MANAGER\_AUTO\_UPDATE</code> lets Homebrew or WinGet installations run the upgrade in the background and prompt to restart</div>

50 <div><code>CLAUDE\_CODE\_SESSION\_ID</code> is now in the Bash tool subprocess environment, matching the <code>session\_id</code> passed to hooks</div>

51 <div><code>/mcp</code> now shows the tool count for connected servers and flags servers that connected with 0 tools</div>

52 <div><code>--channels</code> now works with console (API key) authentication</div>

53 <div>Subprocesses such as Bash, hooks, MCP, and LSP no longer inherit <code>OTEL\_\*</code> environment variables, so OTEL-instrumented apps run via the Bash tool no longer pick up the CLI's own OTLP endpoint</div>

54 <div>Sub-agent progress summaries now hit the prompt cache, cutting <code>cache\_creation</code> token cost by roughly 3x</div>

55 <div>Several OAuth and credential reliability fixes: parallel sessions no longer dead-end at 401 after a refresh-token race, MCP OAuth refresh tokens are no longer lost when multiple servers refresh concurrently, and a rare login loop from a concurrent credential write is fixed</div>

56 <div>New <code>parentSettingsBehavior</code> admin key lets admins opt SDK <code>managedSettings</code> into the policy merge</div>
