Cache Overhaul: delivering 30–40% faster transaction processing
Higher Single-Account Compute Limit: raises the single account limit to 40% of a block’s CUs
New Scheduler TransactionView Struct: improving scheduling efficiency
eXpress Data Path (XDP) for Turbine: a prerequisite for 100 million CU blocks
Increased CPI Nesting Depth: raises the CPI nesting limit from 4 to 8
Relax Entry Constraints: simplifies scheduling logic and is necessary for async execution
Faster Startup Times: nodes now come back online faster
Loaded Transaction Data Size Specification: standardizes how loaded transaction data is calculated
RPC Improvements: faster, more reliable real-time updates for dApps using PubSub WebSockets
WebSockets introduce a host of challenges that can undermine reliability, which is detrimental in high-throughput environments such as Solana. Issues ranging from random disconnects to inadequate filtering have historically compelled developers to dedicate significant time and effort to custom mitigations, often at the expense of core product innovation.
We’re now excited to announce that Enhanced WebSockets are now powered by the same infrastructure that powers LaserStream, our next-gen gRPC streaming service built for speed, simplicity, and fault-tolerance.
This integration provides gRPC-level reliability to WebSocket streams in a JSON-native format, eliminates fragile connections, and enables frontend developers to focus on delivering the best UX possible.
