🚀 🙌 First major version in almost 4 years! 🚀 🤯
Thanks everybody for having the patience. Hopefully this version brings many improvements to your developer experience!

Breaking changes 💥

• Minimum supported Node.js version is now 14+
• Removed deprecated APIs - #993
  • Import paths express-validator/check and express-validator/filter
  • Sanitization-only middlewares (e.g. sanitize(), sanitizeBody(), etc)
  • Deprecated TypeScript types (ValidationParamSchema and ValidationSchema)
• isObject() validator now assumes options.strict = true by default
• Validation errors changed shape
  • Field validation errors param property has been renamed to path
  • oneOf() validation errors no longer have a param: '_error' property
• (TypeScript only) The ValidationError type is now a discriminated union, it might be necessary to use switch or if statements to check that you're dealing with the type that you want to debug/format
• oneOf() signature changed: from oneOf(chains, message) to oneOf(chains, options: { message, errorType })
• oneOf() default error structure now groups errors by their... validation group!, instead of in a flat list
