-This release refreshes PumpFun V2 and USDC quote-pool handling, keeps the default RPC submit lane active alongside SWQoS lanes, restores the fast-submit result window to 5 seconds, and aligns Raydium CPMM fixed-output swaps with the on-chain `swap_base_out` instruction. Trade execution requires a caller-supplied `recent_blockhash` or durable nonce; hot-path execution does not query RPC for blockhash, account, or balance data.

 ## ✨ Features
 
-1. **PumpFun Trading**: Unified SDK-side `buy`, `sell`, and `buy_exact_quote_in` flow, selecting legacy or V2 on-chain instructions as needed (SOL + USDC)

 3. **Bonk Trading**: Support for Bonk trading operations
 4. **Raydium CPMM Trading**: Support for Raydium CPMM (Concentrated Pool Market Maker) trading operations
