🚀 Arch Network v0.5.0 Release Notes

Highlights

Initial implementation of on-chain governance primitives, including stake delegation, vote tracking, and caching optimizations.

Enables configurable fee payer accounts for more flexible transaction handling.

Strengthened VM safety with trait-based sanitization and new test coverage for re-entrancy edge cases.

Added support for tracking and limiting compute usage per transaction to prepare for production-grade resource management.

A minimal working example of an orderbook leveraging APL token standards, now with market order support and cleaner structure.

Enhanced the robustness of distributed key generation (DKG), including better leader retry logic and message filtering.

Unified Docker setup, simplified local dev workflow, improved arch sdk, and better error messages (e.g., removed unsafe unwraps).

Core runtime logic added to handle replaying historical transactions securely and deterministically.

Significant improvements to node liveness, twin node functionality, connection recovery, and roasting continuation after restart.

Added serde to key enums and enhanced identity generation and printing during bootstrap.

Added stake + escrow usage demo and full-block helpers for dApp developers.

Removed deprecated programs, resolved merge conflicts, refactored syscalls, and improved build tooling across the repo.
