## 🚀 Key Features

### 1. Atomic Function Documentation

**Before v1.6.0**: 15-20 individual API calls
```python
rename_function(addr, "ProcessEvent")
set_function_prototype(addr, "void ProcessEvent(int param1)")
rename_variable(func, "param1", "eventType")
set_plate_comment(addr, "Processes UI events")
# ... 15+ more calls
```

**After v1.6.0**: 1 atomic API call
```python
document_function_complete(
    function_address="0x401000",
    new_name="ProcessEvent",
    prototype="void ProcessEvent(int eventType)",
    variable_renames={"param1": "eventType"},
    plate_comment="Processes UI events",
    labels=[{"address": "0x401010", "name": "handle_click"}],
    decompiler_comments=[{"address": "0x401020", "comment": "Validate event"}]
)
# ✅ All operations succeed or all roll back
```

### 2. Pre-flight Validation

**Prevent errors before they happen:**
```python
# Validate type exists
result = validate_data_type_exists("MyStruct")
# {"exists": true, "type_category": "struct", "size": 28}

# Validate prototype syntax
result = validate_function_prototype(
    function_address="0x401000",
    prototype="int foo(char* bar)"
)
# {"valid": true, "parsed_return_type": "int", ...}

# Check rename capability
result = can_rename_at_address("0x401000")
# {"can_rename_data": false, "type": "code", "suggested_operation": "rename_function"}
```

### 3. Enhanced Function Search

**Powerful filtering and sorting:**
```python
# Find undocumented functions with 2+ xrefs
search_functions_enhanced(
    name_pattern="FUN_",
    min_xrefs=2,
    has_custom_name=False,
    sort_by="xref_count",
    limit=50
)

# Regex search for specific patterns
search_functions_enhanced(
    name_pattern="^Process.*Event$",
    regex=True,
    calling_convention="__fastcall"
)
```

### 4. Comprehensive Function Analysis

**Single call for complete analysis:**
```python
result = analyze_function_complete(
    name="FUN_401000",
    include_xrefs=True,
    include_callees=True,
    include_callers=True,
    include_disasm=True,
    include_variables=True
)
# Returns: decompiled code, xrefs, call graph, disassembly, variables
# Replaces 5+ individual API calls
```

## 🔄 Migration Guide

### Breaking Changes
**NONE** - All changes are 100% backward compatible

### New Recommended Workflows

#### Function Documentation (Recommended)
```python
# OLD WORKFLOW (still works)
rename_function(addr, name)
set_function_prototype(addr, prototype)
# ... multiple individual calls

# NEW WORKFLOW (recommended)
document_function_complete(
    function_address=addr,
    new_name=name,
    prototype=prototype,
    variable_renames={...},
    labels=[...],
    plate_comment="...",
    # All operations atomic
)
```

#### Function Analysis (Recommended)
```python
# OLD WORKFLOW (still works)
decompiled = decompile_function(name)
xrefs = get_function_xrefs(name)
callees = get_function_callees(name)
callers = get_function_callers(name)

# NEW WORKFLOW (recommended)
result = analyze_function_complete(
    name=name,
    include_xrefs=True,
    include_callees=True,
    include_callers=True
)
# Single call with all data
```

## 🐛 Known Issues

### Resolved in This Release
- ✅ No way to validate operations before execution (FIXED - validation tools added)
- ✅ Complex workflows require 15-20 API calls (FIXED - atomic operations added)
- ✅ No advanced function search capabilities (FIXED - enhanced search added)
- ✅ Documentation scattered across root and docs/ (FIXED - reorganized)

### Remaining (Low Priority)
- ⚠️ `readMemory` endpoint exists but no Python wrapper (use `inspect_memory_content` instead)
- ⚠️ Legacy camelCase endpoints (renameData, renameFunction, renameVariable) still exist for compatibility
