## Full text

What's changed Claude in Chrome is now generally available Added background agent notifications in claude agents — sessions that need input or finish now fire the Notification hook (agent_needs_input / agent_completed) Added /dataviz skill for chart and dashboard design guidance with a runnable color-palette validator Gateway: added Claude Platform on AWS (anthropicAws) as an upstream provider; model-not-found responses now advance the failover chain Background agents launched from claude agents now commit, push, and open a draft PR when they finish code work in a worktree, instead of stopping to ask The built-in Explore agent now inherits the main session's model (capped at opus) instead of running on haiku Subagents and context compaction now inherit the session's extended thinking configuration, improving output quality on delegated tasks Fixed brief network drops mid-response aborting the turn — transient errors like ECONNRESET now retry with backoff instead of failing Fixed excessive background classifier requests when sandboxed processes repeatedly accessed the same network host Fixed background tasks in web, desktop, and VS Code task panels getting stuck on "Running" after they finish or after resuming a session Fixed agent teams: a teammate that dies on an API error now reports "failed" to the lead, and messaging a stuck teammate wakes it to retry immediately Fixed the /diff panel not refreshing when you switch branches or commit outside the session Fixed markdown tables overflowing and wrapping their right border when rendered in fullscreen mode Fixed Claude Platform on AWS and Mantle sessions dead-ending with "Please run /login" when the STS token expires — awsAuthRefresh now runs automatically Fixed "no route to host" for local-network hosts in macOS background agent sessions by declaring Local Network entitlements Fixed /desktop failing with "Cannot determine working directory" after entering and exiting a worktree Fixed background agents repeatedly showing "Reconnecting…" every ~52 seconds on macOS while the agents view was open Fixed pressing ← inside claude attach <id> exiting to the shell instead of opening the agent view Fixed claude --bg silently creating an unattachable session when combined with --print/-p; the conflicting flags are now rejected up front Fixed the workflow progress view dropping the earliest agents from the list while the phase counter stayed correct in SDK and desktop-app sessions Fixed .claude/rules/ conditional rules not loading when the target file is reached via a symlinked path Fixed Cmd+click not opening URLs in fullscreen mode in Warp on macOS Fixed double-click word selection in fullscreen mode to select the entire URL including the scheme Fixed plan mode not auto-allowing read-only tool calls when a session starts in plan mode Fixed /branch deriving its default fork name from the compaction summary instead of the first real prompt Improved focus mode: subagents launched in a turn now appear in its activity summary, and completed background notifications fold into a single count Improved syntax highlighting accuracy in code blocks, diffs, and file previews by upgrading to highlight.js 11 Keyboard shortcut hints now show opt/cmd instead of alt/super when connected from a Mac over SSH Improved API retry UX: the error reason is now shown after the second attempt, and a status page link replaces the spinner tip when the API is overloaded /login now opens the sign-in dialog from the claude agents view instead of saying it isn't available Subagents now treat messages from the agent that launched them as normal task direction; an agent's message is still never treated as the user's approval Removed the /agents wizard; ask Claude to create or manage subagents, or edit .claude/agents/ directly
