## 2.1.144

- 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 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.
