 ## [Unreleased]
 
-### Added
+### Planned
 
-- Steel framework support (planned)
-- Enhanced testing utilities (compute units, account state validation)
+- Steel framework support
+- Enhanced testing utilities (account state validation)
 - Integration with popular Solana testing patterns
 
+## [0.2.0] - 2024-06-11
+
+### Added - CU Benchmarking Framework
+
+- **Systematic CU analysis framework** with instruction and transaction paradigms
+- **Dual benchmarking modes**: Pure instruction measurement vs complete transaction workflows
+- **Statistical analysis engine** with percentile-based estimates (min, conservative, balanced, safe, very_high, unsafe_max)
+- **Rich execution context discovery** through simulation (SVM state, program details, CPI analysis)
+- **Professional tooling integration** with env_logger and clean JSON output
+- **Comprehensive unit tests** (324 lines) covering edge cases and percentile calculations
+
+### Framework Features
+
+- `InstructionBenchmark` trait for pure CU measurement without framework overhead
+- `TransactionBenchmark` trait for multi-program workflow analysis
+- Two-phase measurement: simulation for context + execution for statistics
+- Address book system for human-readable program names
+- Type-safe domain modeling with `StatType` enum
+
+### Examples & Documentation
+
+- **Working benchmarks**: SOL transfer (150 CU), SPL token transfer, token setup workflow (28K-38K CU)
+- **Comprehensive guide**: [`BENCHMARKING.md`](crates/litesvm-testing/BENCHMARKING.md) with living documentation approach
+- **Enhanced README**: Repositioned as testing + benchmarking platform
+
+### Technical Improvements
+
+- Fixed percentile calculation bugs that showed incorrect variance
+- Removed automatic ComputeBudgetInstruction for measurement transparency
+- SVM state accumulation for realistic vs isolated measurements
+- Professional logging (quiet by default, optional progress via RUST_LOG)
+
+### Breaking Changes
+
+- None - all existing testing functionality preserved
+- New benchmarking features require `--features cu_bench` opt-in
+
