# 1.0.1: New Analyzers & Improved Accuracy

Dec 28, 2025 · New · legacy Python tool

Security, performance, and complexity analyzers with context-aware confidence scoring.

## Highlights

- **Security analyzers**: Detect SQL injection, SSRF, and weak cryptography patterns.
- **Performance analyzers**: Identify N+1 query patterns and inefficient loops.
- **False positive reduction**: Context-aware analysis with confidence scoring and rule whitelisting.

## Major features

- **Security analyzers.** Detect SQL injection, SSRF, and weak cryptography patterns.
- **Performance analyzers.** Identify N+1 query patterns and inefficient loops.
- **Complexity analyzers.** Flag deeply nested loops and excessive method chaining.
- **False positive reduction.** Context-aware analysis with confidence scoring and rule whitelisting.
- **Test coverage.** 96.8% coverage across all analyzer modules with comprehensive edge case tests.
