Version 2.0.57

What: A comprehensive plugin versioning and caching system that stores plugins by version in a dedicated cache directory, supporting multiple installation scopes (user/project).

How to enable: The feature is controlled by the tengu_enable_versioned_plugins experiment flag.

Details:

• Plugins are cached at ~/.claude/plugins/cache/{scope}/{plugin-name}/{version}/
• New V2 file format (installed_plugins_v2.json) supports multiple installations per plugin
• Intelligent component copying analyzes plugin manifests to copy only necessary files
• Version resolution uses manifest version, git SHA (12 chars), npm registry, or timestamp
• Automatic migration from V1 format when enabled
• Evidence: New functions _lA() at line 165557, klA() at line 165606, pQB() at line 165628, C59() at line 476313

What: Promotional UI elements that inform eligible users about their 3 available guest passes for sharing Claude Code.

How it appears:

• Banner in header showing [✻] [✻] [✻] · 3 guest passes at /passes
• Sidebar feed card with styled guest pass promotion
• Only shown to eligible users who haven't visited /passes yet
• Stops showing after 3 impressions

Details:

• Uses existing /passes command infrastructure (the command existed in v2.0.56)
• Tracks passesUpsellSeenCount and hasVisitedPasses in persistent state
• Analytics events: tengu_guest_passes_upsell_shown, tengu_guest_passes_visited
• Evidence: New functions E69() at line 474712, O69() at line 474842, HT3() at line 474824, CI1() at line 474832

What: Automatically disables extended glob patterns in bash and zsh before executing commands to prevent unexpected shell expansion.

How to use:

# Runs automatically - no user action needed
# Before your command executes, Claude Code now runs:
# Bash: shopt -u extglob
# Zsh: setopt NO_EXTENDED_GLOB

Details:

• Prevents patterns like !(pattern), +(pattern), *(pattern) from expanding
• Only applies to bash and zsh shells
• Errors are silently suppressed to avoid breaking command execution
• Evidence: New function NO6() at line 244643, integrated at line 244719

What: Commands that combine directory changes (cd) with output redirection (>, >>) now require explicit user approval.

Details:

• Prevents potential path resolution bypass when final working directory cannot be determined
• Error message: "Commands that change directories and write via output redirection require explicit approval"
• Applies to compound commands like cd /tmp && echo "data" > file.txt
• Single commands without cd or without redirection are unaffected
• Evidence: Enhanced function j85() at line 310479, new parameter G for cd detection

The first-run dialog that prompted users to set up CLAUDE.md has been removed. The /init command remains available for manual use.

Removed functions D89() at line 474327, H89() at line 474425, C89() at line 474428 in v2.0.56

When resuming a conversation from a different directory, the UI now renders a proper React component instead of writing directly to stdout before exit. This provides more reliable message display with a 100ms delay to ensure rendering completes.

New component mb3() at line 519894, state-based rendering at line 519854

Internal upgrade to a newer version of the Zod schema validation library, including JSON Schema generation improvements and new validation utilities.

New class z50 at line 405825, new functions for JSON schema conversion at line 406332

Fixed potential negative dimension calculation when rendering borders in narrow terminal widths.

Modified function r26() at line 218562, added Math.max(0, ...) for width/height calculations

Changed timing of remote ingress URL setting during session hydration to occur in a finally block, ensuring it's set even if hydration fails.

Modified function dH9() at line 513155, moved setRemoteIngressUrl to finally block at line 513248
