June 2025 performance summary for Shopify/nixpkgs: Implemented stability enhancements to the update tooling and the build pipeline. Fixed semantic versioning parsing for the Erigon update script to ensure only standard semantic versions (X.Y.Z) are recognized, preventing mis-identification of pre-release or non-standard strings. Strengthened build reliability by adding the missing 'whenever' dependency to the Prefect package configuration, addressing a build failure not captured by the automated script. These changes reduce release risk, improve CI reliability, and accelerate safe deployments across nixpkgs. Commits: 8b618490f18d88d08c56be277d76aa5cb6ad70a1 (erigon: fix update script); b181066893ca5221cc765cba413416f86cd21097 (prefect: fix build).
