+Changelog: @dagrejs/graphlib (v3.0.0+)
+
+Major Improvements & Modernization
+Organization Migration: Transitioned package ownership to the @dagrejs scope for long-term community maintenance.
+
+Toolchain Overhaul: * Replaced JSHint with ESLint for modern syntax support and stricter code quality.
+
+Removed legacy build tools including Karma, Browserify, and Bower.
+
+TypeScript Enhancements: * Significant updates to index.d.ts to improve IntelliSense and type safety.
+
+Refined generic type definitions for Graph, Node, and Edge objects.
+
+Fixes & Refactoring
+Formatting Standardization: Resolved the conflict between .eslintrc and .editorconfig to enforce a consistent 2-space indentation across the codebase.
+
+Dependency Audit: Cleared high-severity security vulnerabilities by updating core devDependencies via Dependabot.
+
+Project Structure: Cleaned up the root directory by removing deprecated configuration files (bower.json, karma.conf.js).
+
+Breaking Changes
+Bower Support Dropped: Official support for Bower has been removed. Users are encouraged to migrate to npm or yarn.
+
+Development Workflow: Developers contributing to the library must now use npm run lint (ESLint) instead of the previous JSHint commands.
