## What's New in v3.11.0 (Current Release)
18+
## What's New in v4.0.0 🎭 **PARADIGM SHIFT**
19+
20+
### **Meta-Orchestration: AI Agents That Compose Themselves**
21+
22+
**The breakthrough:** Instead of manually wiring agent workflows, v4.0 introduces a meta-orchestration system that analyzes tasks, selects optimal agent teams, chooses composition patterns, and learns from outcomes.
23+
24+
**What this means:**
25+
26+
- 🧠 **Automatic task analysis** → Determines complexity, domain, required capabilities
27+
- 🤝 **Dynamic team composition** → Selects optimal agents from 7 pre-built templates
28+
- 📐 **Intelligent strategy selection** → Chooses from 6 composition patterns (Sequential, Parallel, Debate, Teaching, Refinement, Adaptive)
29+
- 📚 **Self-learning** → Saves successful compositions and improves over time
30+
-**Production-ready workflows** → Release Prep (parallel validation), Test Coverage Boost (sequential improvement)
31+
32+
### Quick Start
33+
34+
**Release preparation with 4 parallel agents:**
35+
36+
```bash
37+
empathy orchestrate release-prep
38+
```
39+
40+
Automatically runs:
41+
42+
- **Security Auditor** (vulnerability scan)
43+
- **Test Coverage Analyzer** (gap analysis)
44+
- **Code Quality Reviewer** (best practices)
45+
- **Documentation Writer** (completeness check)
46+
47+
**Boost test coverage to 90%:**
48+
49+
```bash
50+
empathy orchestrate test-coverage --target 90
51+
```
52+
53+
Sequential workflow:
1754

18-
### **Phase 2 Performance Optimizations: 46% Faster, 15% Less Memory**
55+
1. **Coverage Analyzer** → Identify gaps
56+
2. **Test Generator** → Create tests
57+
3. **Test Validator** → Verify coverage
1958

20-
**Data-driven performance improvements based on comprehensive profiling.**
59+
### Python API
2160

22-
-**46% faster project scans** (9.5s → 5.1s for 2,000+ files)
23-
-**66% faster pattern queries** with intelligent caching
24-
-**15% less memory** through generator expression migrations
25-
-**3-5x faster lookups** via O(n) → O(1) optimizations
26-
-**Zero breaking changes** - 100% backward compatible
61+
```python
62+
from empathy_os.workflows.orchestrated_release_prep import (
63+
OrchestratedReleasePrepWorkflow
64+
)
65+
66+
# Create workflow with custom quality gates
67+
workflow = OrchestratedReleasePrepWorkflow(
68+
quality_gates={
69+
"min_coverage": 90.0,
70+
"max_critical_issues": 0,
71+
}
72+
)
73+
74+
# Execute
75+
report = await workflow.execute(path=".")
76+
77+
if report.approved:
78+
print(f"✅ Release approved! (confidence: {report.confidence})")
79+
else:
80+
for blocker in report.blockers:
81+
print(f"{blocker}")
82+
```
83+
84+
### 6 Composition Patterns
85+
86+
The meta-orchestrator automatically selects the best pattern:
87+
88+
1. **Sequential** (A → B → C) - Pipeline processing
89+
2. **Parallel** (A ‖ B ‖ C) - Independent validation
90+
3. **Debate** (A ⇄ B ⇄ C → Synthesis) - Consensus building
91+
4. **Teaching** (Junior → Expert) - Cost optimization
92+
5. **Refinement** (Draft → Review → Polish) - Iterative improvement
93+
6. **Adaptive** (Classifier → Specialist) - Right-sizing
94+
95+
### Learning System
96+
97+
Successful compositions are saved and improved over time:

from empathy_os.pattern_library import PatternLibrary
100+
from empathy_os.orchestration.config_store import ConfigurationStore
101+
102+
store = ConfigurationStore()

31-
library = PatternLibrary()
32-
# Automatically uses O(1) index structures - 5x faster!
33-
patterns = library.get_patterns_by_tag("debugging")
104+
# Find best composition for task
105+
best = store.get_best_for_task("release_prep")
106+
print(f"Success rate: {best.success_rate:.1%}")
107+
108+
# Reuse proven composition
109+
agents = [get_template(a["role"]) for a in best.agents]
