• BREAKING CHANGE: Rename RegExpMatcher to ArrayMatcher

• createFileResponse now includes charset in Content-Type for text-based files.

• Add detectContentType(extension) function that returns a Content-Type header value with charset for text-based types.

• Add mimeTypeToContentType(mimeType) function that converts a MIME type to a Content-Type header value, adding charset for text-based types.

• Use the :authority header to set the URL of http/2 requests.

• BREAKING CHANGE: Remove BuildRequestHandler type. Use RequestHandler type directly instead.

• BREAKING CHANGE: Remove T generic parameter from RequestHandler type. Request handlers always return a Response.

• Export the MatchData type from the public API. This type is required when creating custom matchers for use with the router's matcher option.

• This is the initial release of the component package.

  See the README for more information.

• Revert "Move next-env.d.ts to dist dir": #87311
