### Use crates.io
```toml
# Add to your Cargo.toml
solana-streamer-sdk = "1.5.16"
solana-streamer-sdk = "2.0.1"
```
Parser backend features:
```toml
# Default: sol-parser-sdk parse-borsh backend
solana-streamer-sdk = "1.5.16"
solana-streamer-sdk = "2.0.1"
# Zero-copy parser backend for latency-sensitive bots
solana-streamer-sdk = { version = "1.5.16", default-features = false, features = ["sdk-parse-zero-copy"] }
solana-streamer-sdk = { version = "2.0.1", default-features = false, features = ["sdk-parse-zero-copy"] }
```
If both `sdk-parse-borsh` and `sdk-parse-zero-copy` are enabled, `sol-parser-sdk 0.5.15+` uses the zero-copy backend.
If both `sdk-parse-borsh` and `sdk-parse-zero-copy` are enabled, `sol-parser-sdk 0.6.1+` uses the zero-copy backend.
## 🔄 Migration Guide
### Upgrading to v2.0.1
Version 2.0.1 uses `sol-parser-sdk 0.6.1` from crates.io. PumpSwap Buy/Sell events now preserve the complete current cashback, buyback, signed virtual quote reserve, boost, and base-supply tail through dispatcher and SDK bridge paths. Truncated current layouts are rejected consistently by the default and zero-copy parser backends while historical layouts remain supported.
### 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.
