[Release] anthropics/claude-code v2.1.147: v2.1.147

Claude Code v2.1.147 introduces significant improvements to background session management, renames the `/simplify` command to `/code-review` with enhanced bug detection capabilities, and delivers numerous bug fixes across the auto-updater, shell tools, PowerShell integration, and UI rendering. Key enhancements include better session persistence, improved diff performance, and fixes for enterprise login enforcement. The release addresses 40+ issues spanning headless mode compatibility, plugin management, and cross-platform stability.

Key Points

• •Pinned background sessions now persist when idle, auto-restart to apply updates, and are only shed under memory pressure after non-pinned sessions
• •Renamed `/simplify` to `/code-review` with configurable effort levels (e.g., `/code-review high`) and `--comment` flag for posting findings as inline GitHub PR comments
• •Enhanced auto-updater with transient network failure retries, specific error categorization, OS error code reporting, and version display on failures
• •Improved diff rendering performance for large file edits and fixed prompt history to prevent consecutive duplicate entries
• •Fixed enterprise login restrictions (`forceLoginOrgUUID`, `forceLoginMethod`) not being enforced against third-party and API-key sessions
• •Resolved PowerShell tool issues on Windows including exit code 1 failures with winget/Microsoft Store installations and output dropping with default formatters
• •Fixed shell snapshot dropping user functions with single underscore prefixes and plugin agents dropping multiple `Agent(...)` type declarations
• •Corrected hook condition matching for PowerShell patterns and fixed `/effort` slider initialization to start at current effort level
• •Fixed UI issues including `/help` broken tab headers, `/theme` dialog Esc key responsiveness, and full-screen strobing in Windows Terminal background sessions
• •Resolved text input handling issues including pasted text appearing as placeholders, GNOME Terminal paste failures, and slash commands followed by whitespace being treated as unknown
