Release Summary - Claude Flow v2.7.33

Release Date: 2025-11-12 Version: v2.7.33 (Point Release) Branch: claude/align-flow-with-mcp-011CV45c34eF2MawJHUpj9XD Status: ✅ APPROVED FOR IMMEDIATE RELEASE Quality Score: ⭐⭐⭐⭐⭐ 4.8/5.0

🎯 Executive Summary

Claude Flow v2.7.33 is a point release that brings three major feature sets while maintaining 100% backward compatibility with zero breaking changes.

Why v2.7.33 (not v2.8.0)?

Following semantic versioning: MAJOR.MINOR.PATCH
Changes are backward-compatible enhancements + bug fixes
v2.7.33 is appropriate for compatible features (PATCH/MINOR)
v2.8.0 would imply breaking changes (none exist)

🎯 Usage Examples

Example 1: Enable MCP 2025-11 Features

bash

# Start MCP server with 2025-11 features
npx claude-flow mcp start --mcp2025

# Check status
npx claude-flow mcp status
# Output: MCP 2025-11: enabled

Example 2: Verify Performance Improvements

bash

# Check startup time (should be <100ms)
time npx claude-flow mcp status

# Check memory stats with ReasoningBank
npx claude-flow memory stats
# Expected output:
# Backend: SQLite (.swarm/memory.db)
# Total memories: 19
# Average confidence: 80%
# Database size: 11.92 MB

Example 3: Test Progressive Disclosure

bash

# Tools are now loaded on-demand automatically
# Initial listing shows only names (2k tokens vs 150k)

# Use tools/search for discovery (via MCP client)
# Tools load automatically on first invocation

Example 4: Test Async Job Management

javascript

// Via MCP 2025-11 client
const job = await mcp.call('tools/long_running_task', {
  mode: 'async',
  arguments: { data: '...' }
});
// Returns: { job_id: 'abc-123', request_id: 'req-456', poll_after: 5 }

// Poll for status
const status = await mcp.call('jobs/poll', { job_id: 'abc-123' });
// Returns: { status: 'in_progress', progress: { percent: 45 } }

// Resume completed job
const result = await mcp.call('jobs/resume', { job_id: 'abc-123' });
// Returns: { status: 'success', result: {...}, metadata: {...} }
