```toml
# Add to your Cargo.toml
solana-streamer-sdk = { path = "./solana-streamer", version = "1.5.1" }
solana-streamer-sdk = { path = "./solana-streamer", version = "1.5.2" }

### Use crates.io
```toml
# Add to your Cargo.toml
solana-streamer-sdk = "1.5.1"
solana-streamer-sdk = "1.5.2"
```
Parser backend features:
```toml
# Default: sol-parser-sdk parse-borsh backend
solana-streamer-sdk = "1.5.1"
solana-streamer-sdk = "1.5.2"
# Zero-copy parser backend for latency-sensitive bots
solana-streamer-sdk = { version = "1.5.1", default-features = false, features = ["sdk-parse-zero-copy"] }
solana-streamer-sdk = { version = "1.5.2", default-features = false, features = ["sdk-parse-zero-copy"] }
```
If both `sdk-parse-borsh` and `sdk-parse-zero-copy` are enabled, `sol-parser-sdk 0.5.1+` uses the zero-copy backend.
If both `sdk-parse-borsh` and `sdk-parse-zero-copy` are enabled, `sol-parser-sdk 0.5.2+` uses the zero-copy backend.
## 🔄 Migration Guide
### Upgrading to v1.5.2
Version 1.5.2 uses `sol-parser-sdk 0.5.2` from crates.io. ShredStream delivery now uses the SDK direct-callback path to avoid the extra queue consumer task, reuses parser event buffers across entries, preserves unknown ShredStream `tx_index` as `None`, and keeps `PumpFunCreateToken` filters backward-compatible with `CreateV2` events. User callbacks on the direct path should avoid blocking work.
### Upgrading to v1.5.1
Version 1.5.1 uses `sol-parser-sdk 0.5.1` from crates.io. It improves ShredStream ALT handling by parsing outer instructions best-effort with default placeholders for ALT-loaded accounts, adds dropped-event queue observability, and keeps CPI/inner-only events documented as a ShredStream limitation.
