• Top impact areas: validator (37), structs (12), network (11), db_core (10), arch-cli (10), token-metadata (8), tpu (6), dkg (6), sdk (5), runtime (5), key_manager (5), bootnode (5), resharing (4), local_validator (4), examples (4), bitcoin-internal (4), .github (4), telemetry (3), snapshot-manager (3), programs (3), program (3)

Highlights

• Token Metadata Program: Integrated arch-token-metadata and wired builds into gossip tooling.
• Versioning simplification: Centralized workspace and program versions; workflows now derive VERSION for token and associated-token-account.
• Reliability and correctness: Execution result cache, atomic update fixes, early-error return correctness, and BTC-related account handling hardening.
• Telemetry and DB metrics: Reference-based telemetry with expanded DB metrics for better visibility.
• CLI and UX: Ensured arch-cli outputs base58 addresses; removed deprecated --auto-create-ata from docs/demos.
• Structural refactors: Moved network messages and mode into arch_structs for reuse and clarity.
• Node ops: Support starting using a secret key file; added “with seeds” system program instructions.
• TPU robustness: Added missing error handling in tpu::post_process(); Titan async blocking issue fixed.

Added

• arch-token-metadata program integration and build workflow hook.
• System program instructions “with seeds”.
• Execution result cache.
• Support for starting via a secret key file.
• Reference-based telemetry and DB metrics.

Changed

• Centralized versioning across workspace; workflows derive VERSION for token and associated-token-account.
• Network messages and network mode moved to arch_structs.
• Increased code reuse in account preparation; docs and demo scripts updated.
• Gossip script builds token metadata artifacts.

Fixed

• Atomic update edge cases and early error returns on transaction failure.
• Avoid replacing an account modified by a BTC tx with a state-only tx.
• Defers BTC txid extraction on failures to avoid misleading states.
• Titan blocking in async runtime.
• CLI outputs base58 instead of hex for addresses.
• Walkthrough URL and minor stability fixes.

Performance and Observability

• Execution result cache improves throughput under load.
• Expanded telemetry and DB metrics enhance monitoring and tuning.

RPC and API Changes

• No breaking RPC changes.
• New on-chain program: arch-token-metadata.
• CLI address formatting standardized to base58.

Breaking Changes

• None known.

Migration Guidance

• If importing network messages/mode directly, update imports to arch_structs.
• Ensure any scripts rely on base58 addresses from arch-cli.
• No protocol-level actions required for node operators.

Documentation

• Docs and demo scripts cleaned; deprecated ATA flag removed; walkthrough link fixed.
