- Always derive bonding curve and associated bonding vault from mint (avoids stale cached PDAs / wrong pool).
- Use non-default fee_recipient from parser/stream as account #2 without extra authorization filtering (addresses Pump 6000 NotAuthorized when event fee was rejected).
- Rework resolve_creator_vault_for_ix: default-creator cases, phantom default PDA, fee-sharing vault; add unit tests.
- PumpFunParams: respect explicit mayhem_mode from events; fallback creator_vault via get_creator_vault_pda when resolve returns None.
- Remove unused lazy_static tip-cache stub and lazy_static dependency.

- PumpFunParams::from_trade/from_dev_trade: add mayhem_mode Option; infer Mayhem
via is_mayhem_fee_recipient when None (fixes fee recipient / NotAuthorized 6000
when AMM protocol fee pubkey is used).
- Add is_mayhem_fee_recipient and is_amm_fee_recipient helpers in pumpfun utils.
- Bump solana-* crates to 3.1.12; align tonic/prost; use solana-message for
AddressLookupTableAccount; add solana-system-interface 3.0.
- Update examples and latency script for new PumpFunParams signature.
- SWQoS and transaction builder adjustments for dependency changes.

Bump crate/docs version to 4.0.2 and add release notes covering IPv4/IPv6 address-family handling, direct-IP candidate preference, and endpoint failover rotation for more stable low-latency QUIC submission.

## Changes since v4.0.0
### Bug Fixes
- Fixed BlockRazor gRPC endpoints to use correct gRPC service URLs
- Set gRPC as the default transport layer for BlockRazor with HTTP fallback
This release improves the reliability and performance of BlockRazor integration by prioritizing gRPC communication while maintaining HTTP fallback compatibility.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Major changes:
- Switch BlockRazor default transport from gRPC to HTTP to avoid FRAME_SIZE_ERROR
- gRPC mode still available via explicit SwqosTransport configuration
- Fix ZeroSlot Binary-Tx JSON-RPC 2.0 response parsing
- Properly handle success responses with "result" field
- Properly handle error responses with "error" field containing code and message
- Update version to 4.0.0
- Update README files to reflect new version
Technical details:
- BlockRazor: HTTP mode is now the default (SwqosTransport::Http or None)
- ZeroSlot: Parse JSON-RPC 2.0 format responses instead of plain text
- Proto code: Pre-generated gRPC code for BlockRazor (no protoc required)

- Add TradeConfig::with_swqos_cores_from_end(bool) to use last N CPU cores for SWQOS, reducing contention with main thread and default tokio workers.
- Add recommended_sender_thread_core_indices(swqos_count) to get the same last-N core indices for with_dedicated_sender_threads (recommended combo for lower latency).
- Document core affinity and latency in async_executor and with_dedicated_sender_threads.

- 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
- Add pumpfun_copy_trading and pumpfun_sniper_trading to workspace members
- Add grpc_recv_us field to all TradeBuyParams/TradeSellParams in examples
- Switch address_lookup and nonce_cache to sol-parser-sdk, use event is_cashback_coin
- Remove invalid rustls call from pumpfun examples for successful build
- All 18 examples pass cargo check --workspace
Made-with: Cursor
- Bump version to 3.5.4; update README and README_CN
- Astralane: irisb binary API (no Base64), POST /irisb with query api-key&method; constants use /irisb endpoints; ping POST getHealth
- BlockRazor: Send Transaction v2 (plain Base64 body, Content-Type text/plain, auth in URI only); ping POST /v2/health; use default_http_client_builder
- SWQOS: all clients use default_http_client_builder (nextblock, temporal, zeroslot, astralane, lightspeed, jito, flashblock); remove unused Duration imports
Made-with: Cursor
These examples depend on a local path to sol-parser-sdk which is not
available in the public repo, causing build failures for consumers.
