- Bump version to 3.6.4 in Cargo.toml
- Update version references in README.md and README_CN.md
- Add RELEASE_v3.6.4.md with English release notes
- All workspace examples verified to compile (cargo build --workspace)
- Remove RELEASE_v3.6.3.md and docs/ASYNC_EXECUTOR_REVIEW.md
- Minor updates in types, lib, transaction_builder, async_executor, executor, params
Made-with: Cursor
- transaction_pool: add PARALLEL_SENDER_COUNT (18), ensure prefill >= 18 so
multi-channel build never serializes; prefill 64 with max(PREFILL, 18)
- async_executor: document that pool prefill must match sender thread count
- executor: do not sort submit_timings (avoids any extra work); comment that
log order is completion order
- docs: add ASYNC_EXECUTOR_REVIEW.md
- remove RELEASE_NOTES_v3.6.2.md; minor example/types/lib/params updates
Made-with: Cursor
- Log build_instructions / before_submit once; per-channel submit, confirmed, total (all from grpc_recv_us)
- confirmed = per-channel submit-to-confirm duration; total = batch start-to-confirm when need_confirm
- No logging between execute_parallel and poll_any_transaction_confirmation to reduce latency
- Clone submit_timings only when log_enabled; all logging after result is ready
- Use provider name (Jito, Helius, etc.) in log lines instead of generic SWQOS
- Timing format: .4 ms; simulate (dry-run) label for simulate mode
- execute_parallel returns 4-tuple with submit_timings for per-channel timing
Made-with: Cursor
- Add Helius Sender client (helius.rs) with dual routing and swqos_only mode
- Helius min tip: 0.0002 SOL default, 0.000005 SOL when swqos_only=true
- Add TradeConfig.check_min_tip (default false) to skip min-tip validation for lower latency
- Thread check_min_tip through SwapParams and execute_parallel; only call min_tip_sol when enabled
- Add SWQOS_ENDPOINTS_HELIUS and HELIUS_TIP_ACCOUNTS in constants
- Extend SwqosConfig/SwqosType for Helius; add Helius to get_endpoint and get_swqos_client
- Update trading_client, shared_infrastructure and middleware_system examples
Made-with: Cursor
In v3.5.0, confirmation was split out of execute_parallel into
poll_transaction_confirmation, but it only polled sig[0]. When
multi-channel submit is used, each channel produces a different
signature and only one lands on-chain. If the landed sig is not
sig[0], the poll times out after 15s and reports failure despite
a successful on-chain transaction.
Add poll_any_transaction_confirmation() that passes all signatures
to get_signature_statuses in a single RPC call per poll, returning
the first one that confirms. The executor now uses this instead of
polling a single signature.

Replace the global AddressLookupTableCache with a direct fetch function to simplify address lookup table management. This change improves code maintainability by removing global state and makes the API more explicit.
Key changes:
- Remove AddressLookupTableCache and AddressLookupManager
- Add new fetch_address_lookup_table_account function
- Update TradeBuyParams and TradeSellParams to use AddressLookupTableAccount instead of Pubkey
- Update all examples to use the new direct fetch approach
- Update documentation to reflect the simplified workflow
- Bump version from 1.2.0 to 1.2.1
- Change trade methods return type from Signature to (bool, Signature)
- Improve parallel execution error handling and status tracking
- Update CLI examples to match new API interface
- Enhance transaction success/failure reporting capabilities
Breaking Change: Trade API now returns tuple (success_status, signature)
- 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
