v1.0.0-beta.28

Patch Changes

• fe77a3d: 处理 Binance PAPI 私有 WS ACCOUNT_CONFIG_UPDATE 事件，使用 ac.s/ac.l 实时更新已有仓位的 leverage。

v1.0.0-beta.27

Major Changes

• f05af49: Replace market websocket subscribe/unsubscribe methods with per-consumer subscription leases. Use client.market.acquireL1BookSubscription() and client.market.acquireFundingRateSubscription() to obtain a MarketSubscriptionLease, await lease.ready for the first snapshot, and call lease.close() to release only that consumer. L1 book and funding rate streams now ref-count active leases independently and only close the underlying websocket stream after the final lease is closed.

v0.4.0-beta.26

Minor Changes

• 8fb896f: Add client.market.fetchFundingRateHistory() for Binance perpetual funding rate history queries.
• 5711f3d: Add client.market.fetchPublicTrades() for public aggregate market trades and make client.market.fetchPublicRawTrades() ready for Binance raw historical trades when a market API key is configured. fetchPublicTrades() uses public aggTrades without credentials; fetchPublicRawTrades() uses aggTrades as a locator and then historicalTrades with CreateClientOptions.market.venues.binance.apiKey or BINANCE_MARKET_API_KEY, so its available lookback follows the data available from both Binance endpoints.

v0.4.0-beta.25

Minor Changes

• 4f2f7db: BREAKING: remove client.order.getSymbolFeeRate(). Fee rate lookup is now owned by the new client.fee manager.

  Add client.fee.subscribe(), client.fee.getSymbolFeeRate(), client.fee.getSymbolFeeRates(), and client.fee.fetchSymbolFeeRate() for account-scoped symbol fee rates. The fee manager keeps a local cache, returns market-type defaults before venue values are available, and slowly refreshes Binance swap rates through the existing PAPI UM commissionRate endpoint.

v0.4.0-beta.24

Minor Changes

• 9c231de: 新增 CreateClientOptions.onMetric 同步可观测性钩子，并公开 MetricType、OnMetric 与 METRIC_NAMES。SDK 现在会输出下单 RTT、WebSocket 消息延迟、WebSocket reconnect 和事件 buffer overflow 指标；未配置 hook 时热路径跳过 latency 与 tags 构造，hook 抛错不会打断主流程。

v0.4.0-beta.23

Minor Changes

• 716185b: 收紧并扩展公开行为：OrderSnapshot.type / raw order type 归一为小写 OrderType 并通过 rawType 保留 venue 原始串；SDK 生成的 client order id 加入进程级熵；account getter 返回冻结快照；stop() 兑现 graceful drain、timeout 和 stopped client 清理，并在停止后通过 assertStarted 拦截新命令。

  新增 Binance PAPI 风控面：私有流 riskLevelChange 会发布 account.risk_level_change，RiskSnapshot 新增 riskLevel，并用事件中的 riskRatio、equity 和 maintenance margin 字段实时回填风险快照。

Patch Changes

• 716185b: 修复内部事件流和恢复流程：AsyncEventBus 的并发 next() pending reader 现在按 FIFO 队列唤醒，close() 会结束全部等待中的 reader；market resumeStreams() 改为并发恢复订阅，并保留每条流自己的错误隔离。

v0.4.0-beta.22

Minor Changes

• 6dc95fa: Breaking: 账户级 venue 专属配置统一迁移到 account.venues.<venue>。移除旧的 account.binance、account.juplend 与顶层 listenKeyKeepAliveMs 配置入口；Binance 私有流、风险轮询与 reconcile 调优项现在放在 account.venues.binance，Juplend RPC/API key 与 polling 配置放在 account.venues.juplend。

  同时改进内部交易所扩展基础设施：Binance 私有链路 symbol 归一化改走共享 market catalog，修正交割合约/私有流映射一致性；流协议层新增可选应用层 heartbeat 钩子，用于后续 OKX/Bybit 等需要客户端文本 ping 的 venue，未配置 heartbeat 的现有 Binance 连接行为不变。

v0.4.0-beta.21

Patch Changes

• 74507eb: 打磨行情流层：优化 decimal 字符串 canonical 快路径和行情 tick 快照复用，移除健康连接下的 per-subscription stale 误判，并为 WebSocket 重连退避加入默认 ±20% jitter。

v0.4.0-beta.20

Minor Changes

• d3bcffa: 新增 Binance 订单逐笔成交事件 events.order.trades()，逐笔暴露成交价量、手续费、maker 标记与 realized PnL；订单快照字段保持不变。

v0.4.0-beta.19

Patch Changes

• 8cf0a72: Binance private signing timestamps now use a default server-time synchronized clock with startup sampling, periodic resync, and timestamp-error-triggered resync. Passing CreateClientOptions.clock continues to fully override signing time and disables the default sampler.
