Merge Risk: High

This major upgrade to ESLint v10 introduces significant and mandatory breaking changes. All projects must migrate to the new "flat config" format (eslint.config.js), as support for the legacy .eslintrc.* configuration files has been completely removed.

Key Breaking Changes:

  • Node.js Requirement: Support for Node.js versions older than v20.19.0 has been dropped.
  • Configuration Overhaul: The legacy .eslintrc configuration system is no longer supported. You must migrate to a eslint.config.js file. ESLint provides codemods to help automate this transition.
  • New Config Lookup Algorithm: ESLint now locates the configuration file by searching up from the directory of each linted file, which improves behavior in monorepos.
  • API Removals: Deprecated methods on the context and SourceCode objects have been removed, which will affect custom rules and plugins.
  • Updated Rules: The eslint:recommended ruleset has been updated, which may result in new linting errors after upgrading.

Recommendation:
This upgrade requires significant action. Do not merge until you have:

  1. Ensured your environment is running Node.js v20.19.0 or newer.
  2. Migrated your project's configuration from .eslintrc to the eslint.config.js flat config format. Review the official migration guide and consider using the provided codemods.
