v0.66.0

Overview

The Hedera JSON-RPC Relay v0.66.0 release brings key improvements to configuration management and system reliability. A major update enhances type inference in ConfigService.get(), ensuring more explicit type resolution and reducing type mismatches across the codebase. This update also establishes a single source of truth for configuration values, improving consistency, maintainability, and correctness by aligning default values with documentation and replacing hardcoded constants with configurable values.

Alongside these refinements, the release includes minor bug fixes, dependency upgrades such as updates to @mui/material, ethers, and go-ethereum, as well as internal improvements like enhanced Grafana dashboard visibility for Ethereum RPC execution methods. These updates contribute to a more reliable and seamless developer experience.
