claude-code

What's changed

• Added /resume support for background sessions — sessions started via claude --bg or agent view now appear alongside interactive ones, marked with bg
• Added elapsed duration to background subagent completion notifications (e.g. "Agent completed · 3h 2m 5s")
• The /plugin browse and discover panes now show when a plugin was last updated
• /model now changes the model for the current session only; press d in the model picker to set a default for new sessions
• Renamed "extra usage" to "usage credits" across CLI copy; /extra-usage is now /usage-credits (old name still works)
• Fixed startup hanging up to 75s when api.anthropic.com is unreachable (captive portal, firewall, VPN issues) — side-channel API calls now time out after 15s
• Fixed garbled terminal output after a missed window-resize event (e.g. dragging a VS Code split-pane divider) — now self-heals on the next frame instead of requiring Ctrl+L
• Fixed progressive terminal display corruption (stale/garbled glyphs) that could appear in very long sessions and only cleared on terminal resize or restart
• Reduced terminal rendering glitches in VS Code by reducing spinner animation color count
• Fixed macOS background sessions crashing with "exit 1 before init" when the project lives under a Full Disk Access-protected folder (regression in 2.1.143)
• Fixed an unrecoverable conversation when reading a file whose image extension doesn't match its contents (e.g. HTML saved as .png) — now falls back to text
• Fewer spurious tool errors during search: head/tail file views now satisfy the read-before-edit check, and a "no matches" result (exit code 1) from egrep, fgrep, git grep, or git diff is no longer reported as a command failure
• Fixed /branch failing with "No conversation to branch" after entering a worktree or in some background sessions
• Fixed pressing Escape in the AskUserQuestion notes field aborting the turn instead of returning to answer selection
• Fixed model selection not applying when changed via the IDE model picker or applyFlagSettings after startup
• Resumed sessions now keep the model they were using instead of picking up another session's /model choice
• Fixed Bedrock and Vertex users unable to select "Opus (1M context)" from the /model picker (regression in v2.1.129)
• Fixed remote-session login failing with "Can't access this organization" for users with forceLoginMethod and forceLoginOrgUUID set
• Fixed MCP servers with paginated tools/list responses only returning the first page, silently dropping tools
• Fixed MCP images with unsupported MIME types (e.g. SVG) breaking the conversation — now saved to disk and referenced in the tool result
• Fixed file descriptor exhaustion when a build runs inside a skill directory — non-.md files no longer trigger skill reloads
• Fixed session title being generated from plugin monitor output instead of the user's first prompt
• Fixed Skill tool failing with permission error in headless mode (regression in v2.1.141)
• Fixed plugins enabled in your own settings showing "not cached" errors after first load on a fresh machine; plugins enabled only by a project's .claude/settings.json now show an actionable claude plugin install hint
• Fixed claude mcp list silently reporting no servers when .mcp.json can't be parsed (e.g. using VS Code's "servers" key instead of "mcpServers") — now shows configuration errors
• Fixed background side-queries on custom ANTHROPIC_BASE_URL setups and Bedrock Mantle not using Haiku — now falls back correctly when a first-party API key is configured or no Haiku model is set
• Fixed scrolling in attached background sessions on Windows — PgUp/PgDn, mouse wheel, and Ctrl+O transcript navigation now work
• Fixed a crash when closing the terminal while attached to a background session
• Fixed ! <cmd> exec sessions not responding to Ctrl+C while attached — now interrupts the running command
• Fixed agent view shell-command rows lingering under Working after completion, and pressing Enter on a completed row re-running the command after its output expired
• Fixed on Windows, pressing ← in claude agents leaving the list unresponsive to keyboard input
• Fixed ghost characters at the left edge when switching panes in Agent View on Windows Terminal with CJK content
• /bg and ←-detach now preserve directories added via /add-dir
• Fixed Edit/Write refusing with "background session hasn't isolated its changes yet" right after detaching a session that was already editing in place
• Fixed claude respawn <id> on a stopped background session showing "stopped" instead of running
• Fixed /resume picker not showing sessions forked from a background session
• Fixed opening a session from claude agents or running claude logs <id> hanging when the background service is unresponsive — now times out after 10s with a recovery hint
• Fixed background Bash tasks spawned by subagents staying "Running" in SDK task panels after the process exits
• Fixed completed or stopped background sessions briefly failing to wake being permanently marked as a startup crash
• Fixed markdown links in claude agents attached sessions rendering as plain text instead of clickable hyperlinks
• Fixed custom spinnerVerbs applying to the post-turn duration message — past-tense built-ins like "Worked for 5s" are restored there
• claude agents / --bg rejection messages now name the specific gate (non-TTY, env var, or setting) instead of a generic message
• claude --bg --name <label> now echoes the name in the post-spawn confirmation
• claude agents: renaming a background session with Ctrl+R now updates the attached session's banner immediately
• Background session worktree isolation guard now applies for non-git VCS users with WorktreeCreate hooks configured
• Plugin marketplace add/update now respects CLAUDE_CODE_PLUGIN_PREFER_HTTPS
• /plugin now returns to the Installed list after enabling, disabling, or uninstalling a plugin
• /doctor now shows an exec-form example when a command hook is missing the command field
• Skill-listing truncation is no longer shown as a startup notification — run /doctor for the full breakdown
• Improved recovery from rare pre-response stream stalls — now retries streaming once instead of falling back to a slower non-streaming request
• Improved SDK/headless MCP startup: pre-wait now overlaps startup instead of blocking before the first turn (up to 2s faster with slow MCP servers)
• The post-survey follow-up hint now appears after every non-dismiss survey response with context-aware copy, making it easier to share more detail via /feedback.
