What it does

BreakShield CI is a GitHub App that automatically detects breaking API changes in every pull request. It parses TypeScript interfaces and OpenAPI specs using a full AST — not regex — and finds exactly which files and lines will break. Results appear as a PR comment and Check Run within seconds. What makes it different: - AST-verified evidence with exact file:line locations - Confidence scoring filters out noise automatically - Blocks merge on HIGH/CRITICAL risk - Free during beta

Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
