ESLint v8.44.0 released

Highlights

• The no-extra-parens rule has a new option ternaryOperandBinaryExpressions.
• eslint.config.js configuration files can now also export a promise that resolves to the configuration array. This can be useful for using ESM dependencies in CommonJS configuration files.
• The context.parserServices property is now deprecated in favor of SourceCode#parserServices. This change is part of the implementation of language plugins.
• ESLint’s default parser espree now supports RegExp v flag with set notation + properties of strings ES2024 syntax. Please note that the core rules have not yet been updated to support this syntax.
