This major upgrade to ESLint v10 introduces significant breaking changes, most notably the complete removal of the legacy .eslintrc configuration system. All projects must migrate to the eslint.config.js (flat config) format.

Key Breaking Changes:

• Removal of .eslintrc: Support for .eslintrc.* and .eslintignore files has been completely removed. [1, 2, 7] You must migrate to a eslint.config.js file. [5, 10] Related CLI flags like --no-eslintrc and --ignore-path are also removed. [1]
• Node.js Version Requirement: Support for Node.js versions older than v20.19.0 has been dropped. [1, 2] You must ensure your environment is running a compatible Node.js version. [5]
• New Config Lookup: The configuration file is now located by searching from the directory of each linted file, which is a change from the previous behavior of searching from the current working directory. [1, 6]
• eslint-env Comments: Using /* eslint-env */ comments will now cause linting errors. [2, 5]

Recommendation:
This upgrade requires a mandatory migration of your ESLint configuration from the legacy .eslintrc format to the modern eslint.config.js flat config format. Follow the official Configuration Migration Guide before upgrading. [2, 10]

WARNING: Hardcoding eslint to 10.0.0 breaks the workspace catalog convention

Every other package in this monorepo uses catalog:devTools, which currently resolves to ^9.39.2 in pnpm-workspace.yaml:25. After this change, the fastify package will run ESLint v10 while the shared @modelcontextprotocol/eslint-config and all other workspace packages still run v9. This breaks monorepo consistency and is especially risky with ESLint v10, which drops legacy config support, changes config lookup behavior, and makes eslint-env comments cause errors.
