Highlights

• Network and gossip: Stream-based gossip with synchronous APIs, bounded channels, and cleanup (removed ping), improving stability and backpressure handling.
• Snapshot streaming: Snapshot creation now streams files, reducing memory spikes and speeding up snapshot generation.
• Storage limits: Hierarchical block storage to avoid EXT4 directory index limits; added RocksDB cache and memtable limits.
• Mempool extraction: Moved mempool into a dedicated crate for clearer ownership and scalability.
• State sync and reliability: Multiple fixes and improvements to state sync and restart handling after DB/block store cleanup.
• Security: Fixed panicking out-of-bounds access in add_signatures_to_transaction (ARC-548).
• Resharing: Resharing now leverages the gossip manager for more reliable coordination.
• SDK and testing: Added InnerInstruction type and expanded syscall test coverage; fixed missing metadata program in release builds.

Added

• Stream-based gossip transport and synchronous gossip APIs.
• Streaming of files during snapshot creation.
• RocksDB cache and memtable limit configuration.
• sdk type: InnerInstruction.
• Manual trigger for SDK sync workflow.
• New monitor crate and supporting types.

Changed

• Extracted mempool into its own crate and updated references across the workspace.
• Gossip stack cleanup: removed ping handling and stale sync code; generalized manager usage for resharing.
• Improved restart behavior after DB/block store cleanup.
• Refactors around account update event publishing and apply-block flow.
• Linux default arg precedence adjustments.

Fixed

• Panicking OOB in add_signatures_to_transaction.
• Snapshot creation stability (streaming) and related error handling.
• Missing metadata program in release builds.
• Various exporter unwraps and stale functions.

Performance and Observability

• Stream-based gossip and bounded channels improve throughput under load and reduce tail latencies.
• Snapshot streaming minimizes memory usage and improves snapshot time predictability.
• RocksDB limits help prevent cache/memtable overgrowth and stabilize I/O behavior.

RPC and API Changes

• No breaking RPC changes.
• SDK: new InnerInstruction type available to consumers.

Breaking Changes

• None known.

Migration Guidance

• No action required for node operators.
• SDK consumers may adopt InnerInstruction as needed.
• No configuration changes required; storage and gossip improvements are backward-compatible.

Documentation

• Updated notes around snapshot streaming, SDK sync triggers, and gossip improvements.
