Highlights

• State Sync V2: New end-to-end state sync pipeline landed, improving sync robustness and throughput.
• Safety and correctness: Added previous_block_hash check for finalization, leader peer ID checks for ROAST, and removed risky unwrap paths in state transitions; fixed partial-update abort behavior.
• Bitcoin integration: Prevents broadcasting a Bitcoin tx when the corresponding Arch tx fails; adds Bitcoin sync initialization tests and ensures Titan is at tip.
• CLI UX: arch-cli now normalizes all user-facing identifiers to base58 for consistency.
• Programs/SDK: Introduced constant program IDs for Token and ATA; ensured program accounts are funded for minimum rent.
• DevEx: Docker stacks updated and made compatible with macOS/Podman; examples and e2e coverage expanded.

Added

• State Sync V2 across the validator/runtime.
• Bitcoin sync initialization tests and tip checks for Titan.
• Redeploy e2e test.
• Constant IDs for Token and Associated Token Account programs.

Changed

• arch-cli: normalize all user-facing identifiers to base58.
• Docker stacks updated; compatibility for macOS/Podman.
• Fund program account for minimum rent.
• Updated examples/helloworld program.
• Removed minimum account lamports constant.
• Hasher trait implementation adjustments.
• Call depth handling tightened.

Fixed

• Avoid unwrap in state transition path.
• Corrected partial update behavior during abort.
• Restored set_last_modified_accounts in block save path.
• Added previous_block_hash finalization check.
• Leader peer ID checks for ROAST and out-of-bounds issues fixed.
• Do not broadcast Bitcoin tx if the Arch tx failed.

Performance and Observability

• State Sync V2 improves synchronization performance and stability; expanded tests increase coverage.

RPC and API Changes

• arch-cli now standardizes to base58 identifiers; no breaking protocol changes.
• Program IDs for Token and ATA are now fixed constants.

Breaking Changes

• None known.

Migration Guidance

• Update to v0.5.9. Ensure scripts/clients pass base58 identifiers to arch-cli.

Documentation

• No major docs added; examples and workflows saw routine updates.
