Arch-Network/arch-node v0.6.3-rc3 on GitHub

This release candidate introduces significant internal refactoring and infrastructure improvements to prepare for the v0.6.3 stable release.

Highlights

CI/CD Infrastructure Overhaul: Consolidated and streamlined GitHub Actions workflows, removing redundant pipelines and improving build efficiency
Crate Organization: Migrated to arch-titan crates structure with improved modularity and dependency management
Transaction Pool Redesign: Introduced hybrid transaction pool implementation with improved state management and performance characteristics
SDK Enhancements: Added async RPC client capabilities and improved program deployment helpers with better error handling
DKG Refactoring: Reorganized Distributed Key Generation module with cleaner trait abstractions and enhanced test utilities
Developer Tooling: Added new CI scripts for eBPF program state computation and automated release note generation

This release includes extensive changes across 304 files with major updates to:

GitHub Actions workflows (consolidated from multiple files into streamlined ci.yml, updated release and nightly build processes)
Docker infrastructure (new wrapper Dockerfiles, improved build scripts, updated Antithesis configuration)
Transaction pool implementation (new hybrid pool with separate state management in transaction_pool/src/hybrid/)
SDK client architecture (split into blocking/async patterns with new transport abstractions)
DKG module structure (renamed files to simpler names, added traits and test utilities)
Database utilities (enhanced genesis block handling and program account tests)
E2E and example tests (updated imports and test patterns throughout)

For Node Operators:

Review updated configuration parameters in validator/default-config-params.toml for transaction pool settings
New Docker wrapper images available for easier deployment workflows
Verify compatibility with updated bootnode health check mechanisms

For Developers:

SDK now provides async alternatives for RPC calls; update client code to use new async_rpc module if needed
Program deployment helpers have been reorganized; check sdk/src/helper/ for new async variants
Transaction pool performance benchmarks have been removed; use new test suite in transaction_pool/tests/
