+### Upgrading to v1.4.7
 
-Version 1.4.6 uses `sol-parser-sdk 0.4.11` from crates.io and supports the Pump.fun / PumpSwap fee-recipient upgrade accounts and Pump.fun v2 trade instructions across Yellowstone gRPC, ShredStream, RPC transaction parsing, and account parsing while preserving the existing subscription and callback API. Existing bots can usually upgrade by changing only the crate version.
+Version 1.4.7 uses `sol-parser-sdk 0.4.11` from crates.io and adds the SDK-compatible Yellowstone gRPC ordering modes to the streamer facade while preserving the existing subscription and callback API. Existing bots can keep the default ultra-low-latency `Unordered` mode or opt into `Ordered`, `StreamingOrdered`, or `MicroBatch` through `ClientConfig`.
 
 New optional capabilities:
 
 - `solana_streamer_sdk::parser_sdk` re-exports the raw `sol-parser-sdk` crate.
 - `solana_streamer_sdk::sdk_bridge` adapts raw SDK events back into streamer `DexEvent`.
 - `fetch_rpc_transaction_as_streamer_events` and `parse_encoded_rpc_transaction_as_streamer_events` parse RPC transactions into streamer events.
+- `grpc::ClientConfig::order_mode` supports `Unordered`, `Ordered`, `StreamingOrdered`, and `MicroBatch`.
 - `sdk-parse-zero-copy` enables the SDK zero-copy parser backend.
