 ## 🔄 Migration Guide
 
+### Upgrading to v1.5.16
+
+Version 1.5.16 fixes `StreamingOrdered` delivery for transactions that parse into multiple events. Events from the same `(slot, tx_index)` are admitted as a group, the streaming watermark advances once per transaction, and stable sorting preserves parser order for equal transaction indexes. It also pins `yellowstone-grpc-proto` to the `12.4.x` API used by `sol-parser-sdk 0.5.15` so CI and clean installs do not resolve an incompatible newer proto crate.
+
 ### Upgrading to v1.5.15
 
 Version 1.5.15 tracks `sol-parser-sdk 0.5.15` at GitHub rev `36ec202`. Pump.fun `create_v2` now distinguishes 16-account SOL-sentinel creates from 19/20-account quote-pool creates, models Yellowstone gRPC loaded writable/readonly addresses correctly, rejects PumpFun program-account fillers as quote mints, and keeps ShredStream from guessing ALT-loaded quote mints when the static transaction keys do not contain them. gRPC/RPC inner instruction parsing now handles guarded 8-byte ordinary CPI instructions for all SDK-supported DEX parsers, so PumpSwap `create_pool` reads `is_cashback_coin` from instruction args before merging with log-derived `CreatePoolEvent` output. ShredStream remains outer-instruction only, but its outer discriminator gate is shared with the SDK parser and no longer diverges for supported DEX protocols.

 如果同时启用 `sdk-parse-borsh` 和 `sdk-parse-zero-copy`，`sol-parser-sdk 0.5.15+` 会优先使用 zero-copy 后端。
 
 ## 🔄 迁移指南
 
+### 升级到 v1.5.16
+
+v1.5.16 修复 `StreamingOrdered` 模式下同一交易解析出多个事件时的投递问题。同一 `(slot, tx_index)` 的事件会作为一组进入缓冲，streaming watermark 每笔交易只推进一次，并用 stable sort 保留相同交易索引下的解析器输出顺序。同时将 `yellowstone-grpc-proto` 固定到 `sol-parser-sdk 0.5.15` 使用的 `12.4.x` API，避免 CI 和干净安装解析到不兼容的新 proto crate。
+
 ### 升级到 v1.5.15
 
 v1.5.15 跟随 GitHub rev `36ec202` 上的 `sol-parser-sdk 0.5.15`。Pump.fun `create_v2` 现在会区分 16 账户 SOL sentinel 创建和 19/20 账户 quote-pool 创建；填充账户时会先选择实际的 create/create_v2 指令，再读取 quote 字段。gRPC/RPC inner instruction 解析现在会按 program id + discriminator 守卫解析所有 SDK 已支持 DEX 的 8-byte 普通 CPI instruction，PumpSwap `create_pool` 因此能从 instruction args 读取 `is_cashback_coin` 并与 log 事件合并。ShredStream 仍只解析外层指令，但外层 discriminator gate 已和 SDK 统一，避免支持协议之间规则分叉。
