Add Meteora DAMM V2 trading protocol with instruction builder, type definitions, and fixed_output_token_amount parameter for precise output control. Update all examples and documentation.
- Merge BuyParams and SellParams into unified SwapParams structure
- Add USD1 token pool support with related constants and configurations
- Refactor trade executor by combining buy_with_tip and sell_with_tip into swap method
- Update all protocol instruction builders to support new parameter structure
- Standardize ATA creation/closing parameter naming conventions
- Update example code to use new API interfaces
- Optimize trading logic with automatic direction detection based on input token type
- Add open_seed_optimize parameter for transaction CU optimization using createAccountWithSeed
- Add create_mint_ata parameter to control automatic mint token account creation
- Update all examples to include new create_mint_ata parameter (set to true)
- Enhance documentation with detailed explanations of seed optimization features
- Add warnings about compatibility requirements when using seed optimization
- Support conditional mint ATA creation across all trading protocols (PumpFun, PumpSwap, Bonk, Raydium)
BREAKING CHANGE: All buy functions now require create_mint_ata parameter
- Replace auto_handle_wsol with create_wsol_ata and close_wsol_ata
- Enable fine-grained control over wSOL account lifecycle
- Update all trading protocols and documentation
- Add open_seed_optimize support in fast functions
This provides better flexibility for batch operations and advanced trading.
- Simplify TradeExecutor interface by integrating middleware and swqos clients into params
- Refactor parallel execution module with dedicated buy/sell execute functions
- Add SOL wrapping/unwrapping functionality for wSOL management
- Remove redundant parameter passing in sell operations
- Delete example main.rs file
- Optimize transaction building with integrated parameter structures
BREAKING CHANGE: TradeExecutor interface simplified, middleware and swqos_clients now passed through params
- Replace dynamic PDA calculations with cached vault addresses for better performance
- Add support for pre-calculated pool state and observation state addresses
- Optimize instruction data creation using fixed-size arrays instead of Vec
- Refactor vault account resolution with fallback to PDA calculation
- Use fast ATA address calculation to reduce computation overhead
- Extract common wSOL handling logic to reduce code duplication
- Add RaydiumCpmmParams::from_trade() constructor for event-driven trading
- Improve memory allocation efficiency with Vec::with_capacity()
- Consolidate protocol constants to unified module
- Pre-build AccountMeta objects using once_cell::Lazy
- Reduce instruction building overhead across all DEX protocols
- Improve code maintainability and performance
- Remove src/common/address_lookup.rs and tip_cache.rs to simplify common modules
- Move protocol-specific utility functions from trading/ to instruction/utils/
- Refactor utility functions for PumpFun, PumpSwap, Raydium AMM V4, and Raydium CPMM
- Consolidate constant definitions by inlining seeds and accounts modules into respective utility files
- Update all import paths to ensure code consistency
- Optimize trading parameter construction and executor logic
- Improve address lookup cache and nonce management mechanisms

Enhanced MEV protection services with FlashBlock and Node1 integration.
Updated instruction modules for bonk, pumpswap, and raydium_cpmm.
Improved SWQOS modules for better transaction handling.
- Add comprehensive calculation utilities for all protocols (bonk, pumpfun, pumpswap, raydium)
- Refactor instruction modules to reduce code complexity and improve maintainability
- Optimize trading parameters structure and enhance common utilities
- Separate calculation logic from trading modules for better code organization
- Update dependencies and module exports
- Add Raydium CPMM constants, instruction builder and pool implementation
- Implement unified buy/sell trading interface and event parsing system
