 # httr2 (development version)
 
+* Export `is_online()` as thin wrapper around `curl::has_internet()` (#512).
 * `curl_translate()` now translates cookie headers to `req_cookies_set()` (#431).
 * `curl_transform()` will now use `req_body_json_modify()` for JSON data (#258).
 * `resp_stream_is_complete()` tells you if there is still data remaining to be streamed (#559).
