• Compare: v0.5.12...v0.5.13
• Date range: 2025-09-23 → 2025-09-30
• Stats: 93 files changed, +3737 / −859
• Top impact areas: validator (15), syscall-bench (13), program (7), examples (6), (root) (6), snapshot-manager (5), ebpf (5), db_core (5), runtime (3), resharing (3), programs (3), network (3), local_validator (3), bitcoin-internal (3), .github (3), tpu (2), runtime-tests (2)

Highlights

• QUIC transport: Switched to QUIC for improved network performance and reliability.
• Rune syscall: Added syscall to retrieve rune information, expanding Bitcoin-related program capabilities.
• Solana compatibility: Restored Solana 2.2.x-compatible sol_log_data ABI and behavior for ecosystem interoperability.
• UTXO validation: State-only transactions now validate UTXOs; anchor checks prevent conflicts; signature checks tightened.
• Snapshot and resharing: Single concurrent snapshot enforcement; snapshot, resharing, rollback, and libp2p telemetry improvements.
• Performance: Switched to jemalloc allocator; benchmarking infrastructure added (syscall-bench).
• SDK sync: apl_token_metadata now included in arch-sdk sync workflow with dynamic dependency pinning.
• Transaction validation: Checks for fee payer affordability and proper errors for stale blockhash.

Added

• QUIC transport layer.
• Syscall to retrieve rune information.
• UTXO validation for state-only transactions.
• Test for UTXO anchoring.
• Benchmarking crate (syscall-bench).
• Fee payer affordability check (can_fee_payer_afford_transaction).
• Error handling for recent blockhash "too old" condition.

Changed

• Network transport: TCP → QUIC.
• Memory allocator: system default → jemalloc.
• Account executable flag: now set even if program is already deployed.
• Snapshot concurrency: enforced single concurrent snapshot.
• SDK sync workflow: includes apl_token_metadata; dynamically pins workspace dependencies.
• sol_log_data ABI restored to Solana 2.2.x compatibility.
• Use include_bytes! instead of rust-embed for embedded assets.

Fixed

• Out-of-bounds (OOB) issue in validator.
• Deployment-related edge cases.
• Signature checks for transactions.
• Renamed and corrected apl_token_metadata references.

Performance and Observability

• QUIC reduces latency and improves throughput.
• jemalloc improves memory allocation patterns under load.
• Benchmarking infrastructure allows systematic performance tracking.
• Expanded telemetry for snapshots, resharing, rollback, and libp2p.

RPC and API Changes

• No breaking RPC changes.
• New syscall: retrieve rune information (programs).
• sol_log_data now matches Solana 2.2.x ABI.

Breaking Changes

• None known.

Migration Guidance

• No action required for node operators or users.
• Programs relying on rune information can now call the new syscall.
• Ensure SDK consumers update to pick up apl_token_metadata if needed.

Documentation

• Benchmarking and syscall docs embedded; workflow and example updates.
