httr2 1.2.0

Lifecycle changes

• req_perform_stream() has been soft deprecated in favour of
  req_perform_connection().

• Deprecated functions mutli_req_perform(), req_stream(), with_mock() and
  local_mock() have been removed.

• Deprecated arguments req_perform_parallel(pool),
  req_oauth_auth_code(host_name, host_ip, port), and
  oauth_flow_auth_code(host_name, host_ip, port) have been removed.

New features

• Redacted headers are no longer serialized to disk. This is important since it
  makes it harder to accidentally leak secrets to files on disk, but comes at a
  cost: you can longer perform such requests that have been saved and reloaded
  (#721).

• URL construction is now powered by curl::curl_modify_url(), and hence now
  (correctly) escapes the path component (#732). This means that
  req_url_path() now can only affect the path component of the URL, not
  the query params or fragment.

• New last_request_json() and last_response_json() to conveniently see
  JSON bodies (#734).

• New req_get_url(), req_get_method(), req_get_headers(),
  req_body_get_type(), and req_get_body() allow you to introspect a request
  object (#718).

• New resp_timing() exposes timing information about the request measured
  by libcurl (@arcresu, #725).

Minor improvements bug fixues

• Functions that capture interrutps (like req_perform_parallel() and friends)
  are now easier to escape if they're called inside a loop: you can press
  Ctrl + C twice to guarantee an exit (#1810).

• req_perform_iterative(), req_perform_sequential(),
  req_perform_parallel(), req_perform_promise(), and
  req_perform_connection() now support mocking (#651). To mock the response
  from req_perform_connection() create a response with the new StreamingBody
  for a body.

• new_response() is now exported (#751).

• req_body_json() and req_body_form() correctly unobfuscated inputs,
  as documented (#754).

• req_body_json_modify() can now be used on a request with an empty body.

• req_error() errors with long bodies are now correctly wrapped (#727).

• req_oauth_device() gains an open_browser argument that lets you take
  control of whether a browser is opened or the URL is printed (@plietar, #763)

• req_perform_parallel() handles progress argument consistently with other
  functions (#726).

• req_url_query() now re-calculates n lengths when using .multi = "explode"
  to avoid select/recycling issues (@Kevanness, #719).

• All print methods now send output to stdout, not the message stream.
