July 2025 development summary across two core repositories focused on reliability, usability, and developer experience. Key outcomes include: 1) release-plz/release-plz: Configuration Validation on Load — the default configuration loader now returns an explicit error if invalid TOML is detected, preventing silent fallbacks to other sources and potential runtime issues (commit bc1905d78df39af229257f869d60c3a62d1142b8). 2) 0xPolygonMiden/miden-client: Miden Client Init Command Improvements (CLI and Network Configuration Guidance) — updated docs and CLI help for the init command to clarify network configuration options and improve user guidance (commit e44f1705f4b34ebee5826b82b216cbe41cb0c492).
