httr2 1.0.1

• req_perform_stream() gains a round = c("byte", "line") argument to control
  how the stream is rounded (#437).

• req_retry() gives a clearer error if after returns the wrong type of
  value (#385).

• req_template() now works when you have a bare : in a template that
  uses "uri" style (#389).

• req_timeout() now resets the value of connecttimeout set by curl.
  This ensures that you can use req_timeout() to increase the connection
  timeout past 10s (#395).

• url_parse() is considerably faster thanks to performance optimisations
  by and discussion with @DyfanJones (#429).

httr2 1.0.0

Function lifecycle

• local_mock() and with_mock() have been deprecated in favour of
  local_mocked_responses() and with_mocked_responses() (#301).

• multi_req_perform() is deprecated in favour of req_perform_parallel().
  req_stream() is deprecated in favour of req_perform_stream() (#314).

• oauth_flow_auth_code() deprecates host_name and port arguments in favour
  of using redirect_uri. It also deprecates host_ip since it seems unlikely
  that changing this is ever useful.

• oauth_flow_auth_code_listen() now takes a single redirect_uri argument
  instead of separate host_ip and port arguments. This is a breaking change
  but I don't expect anyone to call this function directly (which was confirmed
  by a GitHub search) so I made the change without deprecation.

• req_body_form() and req_body_multipart() now require data ...;
  they no longer accept a single list for compatibility with the 0.1.0
  API.

Multiple requests

• New req_perform_sequential() performs a known set of requests
  sequentially. It has an interface similar to req_perform_parallel() but
  with no limitations, and the cost of being slower (#361).

• New req_perform_iterative() performs multiple requests, where each request
  is derived from the previous response (@mgirlich, #8).

• req_perform_parallel() replaces multi_req_perform() to match the new
  naming scheme (#314). It gains a progress argument.

• req_perform_iterative(), req_perform_parallel(), and
  req_perform_sequential() share a new error handling strategy. By
  default, errors will be bubbled up, but you can choose an alternative
  strategy with the on_error argument (#372).

• A new family of functions resps_successes(), resps_failures(),
  resps_requests() and resps_data() make it easier to work with lists of
  responses (#357). Behind the scenes, these work because the request is now
  stored in the response (or error) object (#357).

• resp_body_json() and resp_body_xml() now cache the parsed values so
  that you can use them repeatedly without worrying about the performance cost.
  This supports the design req_perform_iterative() by avoiding the need to
  carefully pass around a parsed object.

OAuth features

• A new vignette("oauth") gives many more details about how OAuth works and
  how to use it with httr2 (#234), and the OAuth docs have been overhauled to
  make it more clear that you should use req_oauth_*(), not oauth_*() (#330).

• If you are using an OAuth token with a refresh token, and that refresh
  token has expired, then httr2 will now re-run the entire flow to get
  you a new token (#349).

• New oauth_cache_path() returns the path that httr2 uses for caching OAuth
  tokens. Additionally, you can now change the cache location by setting the
  HTTR2_OAUTH_CACHE env var. This is now more obvious to the user, because
  httr2 now informs the user whenever a token is cached.

• oauth_flow_auth_code() gains a redirect_uri argument rather than deriving
  this URL automatically from the host_name and port (#248). It uses
  this argument to automatically choose which strategy to use to get the
  auth code, either launching a temporary web server or, new, allowing you to
  manually enter the details with the help of a custom JS/HTML page hosted
  elsewhere, or by copying and pasting the URL you're redirected to
  (@fh-mthomson, #326). The temporary web server now also respects the path
  component of redirect_uri, if the API needs a specific path (#149).

• New oauth_token_cached() allows you to get an OAuth token while still
  taking advantage of httr2's caching and auto-renewal features. For expert
  use only (#328).

Other new features

• @mgirlich is now a httr2 contributor in recognition of his many contributions.

• req_cache() gains max_n, max_size, and max_age arguments to
  automatically prune the cache. By default, the cache will stay under 1 GB
  (#207).

• New req_body_json_modify() allows you to iteratively modify a JSON
  body of a request.

• New req_cookie_preserve() lets you use a file to share cookies across
  requests (#223).

• New req_progress() adds a progress bar to long downloads or uploads (#20).

• New resp_check_content_type() to check response content types (#190).
  resp_body_json() and friends give better errors if no Content-Type
  header is present in the response (#284).

• New resp_has_body() returns a TRUE or FALSE depending on whether
  or not the response has a body (#205).

• New resp_url(), resp_url_path(), resp_url_queries() and
  resp_url_query() to extract various part of the response url (#57).

• req_url_query() gains a .multi parameter that controls what happens when
  you supply multiple values in a vector. The default will continue to error
  but you can use .multi = "comma" to separate with commas, "pipe" to
  separate with |, and "explode" to generate one parameter for each
  value (e.g. ?a=1&a=2) (#350).

• New secret_encrypt_file() and secret_decrypt_file() for encrypting and
  decrypting files (#237).

Minor improvements and bug fixes

• The httr2 examples now only run on R 4.2 and later so that we can use
  the base pipe and lambda syntax (#345).

• OAuth errors containing a url now correctly display that URL
  (instead of the string "uri").

• curl_translate() now uses the base pipe, and produces escapes with single
  quotes or raw strings in case double quotes can't be used (@mgirlich, #264).
  It gains the argument simplify_headers that removes some common but
  unimportant headers, like Sec-Fetch-Dest or sec-ch-ua-mobile
  (@mgirlich, #256). It also parses the query components of the url
  (@mgirlich, #259) and works with multiline commands from the clipboard
  (@mgirlich, #254).

• local_mocked_responses() and with_mocked_responses() now accept a
  list of responses which will be returned in sequence. They also now correctly
  trigger errors when the mocked response represents an HTTP failure (#252).

• oauth_flow_refresh() now only warns, not errors, if the refresh_token
  changes, making it a little easier to use in manual workflows (#186).

• obfuscated() values now display their original call when printed.

• req_body_json() gains custom content type argument
  and respects custom content-type set in header (@mgirlich, #189).

• req_cache() now combine the headers of the new response with the headers
  of the cached response. In particular, this fixes resp_body_json/xml/html()
  on cached responses (@mgirlich, #277).

• req_perform() now throws error with class httr2_failure/httr2_error if
  the request fails, and that error now captures the curl error as the parent.
  If the request succeeds, but the response is an HTTP error, that error
  now also has super class httr2_error. This means that all errors thrown by
  httr2 now inherit from the httr2_error class. See new docs in ?req_error()
  for more details.

• req_perform()'s progress bar can be suppressed by setting
  options(httr2_progress = FALSE) (#251). Progress bars displayed while
  waiting for some time to pass now tell you why they're waiting (#206).

• req_oauth_bearer_jwt() now includes the claim in the cache key (#192).

• req_oauth_device() now takes a auth_url parameter making it usable
  (#331, @taerwin).

• req_url_query() gains a .multi parameter that controls what happens when
  you supply multiple values in a vector. The default will continue to error
  but you can use .multi = "comma" to separate with commas, "pipe" to
  separate with |, and "explode" to generate one parameter for each
  value (e.g. ?a=1&a=2) (#350).

httr2 0.2.3

• New example_url() to launch a local server, making tests and examples
  more robust.

• New throttle_status() to make it a little easier to verify what's happening
  with throttling.

• req_oauth_refresh() now respects the refresh_token for caching
  (@mgirlich, #178).

• req_perform() now always sleeps before a request, rather than after it.
  It also gains an error_call argument and communicates more clearly
  where the error occurred (@mgirlich, #187).

• req_url_path() and req_url_path_append() can now handle NULL or empty
  ... and the elements of ... can also have length > 1 (@mgirlich, #177).

• sys_sleep() (used by req_retry() and req_throttle()) gains a progress
  bar (#202).

httr2 0.2.2

• curl_translate() can now handle curl copied from Chrome developer tools
  (@mgirlich, #161).

• req_oauth_*() can now refresh OAuth tokens. One, two, or even more times!
  (@jennybc, #166)

• req_oauth_device() can now work in non-interactive environments,
  as intendend (@flahn, #170)

• req_oauth_refresh() and oauth_flow_refresh() now use the envvar
  HTTR2_REFRESH_TOKEN, not HTTR_REFRESH_TOKEN (@jennybc, #169).

• req_proxy() now uses the appropriate authentication option (@jl5000).

• req_url_query() can now opt out of escaping with I() (@boshek, #152).

• Can now print responses where content type is the empty string
  (@mgirlich, #163).

httr2 0.2.1

• "Wrapping APIs" is now an article, not a vignette.

• req_template() now appends the path instead of replacing it (@jchrom, #133)

httr2 0.2.0

New features

• req_body_form(), req_body_multipart(), and req_url_query() now
  support multiple arguments with the same name (#97, #107).

• req_body_form(), req_body_multipart(), now match the interface of
  req_url_query(), taking name-value pairs in .... Supplying a single
  list() is now deprecated and will be removed in a future version.

• req_body_json() now overrides the existing JSON body, rather than
  attempting to merge with the previous value (#95, #115).

• Implement req_proxy() (owenjonesuob, #77).

Minor improvements and bug fixes

• httr_path class renamed to httr2_path to correctly match package name
  (#99).

• oauth_flow_device() gains PKCE support (@flahn, #92), and
  the interactive flow is a little more user friendly.

• req_error() can now correct force successful HTTP statuses to fail (#98).

• req_headers() will now override Content-Type set by req_body_*() (#116).

• req_throttle() correctly sets throttle rate (@jchrom, #101).

• req_url_query() never uses scientific notation for queries (#93).

• req_perform() now respects httr::with_verbose() (#85).

• response() now defaults body to raw(0) for consistency with real
  responses (#100).

httr2 0.1.1

• Fix R CMD check failures on CRAN

• Added a NEWS.md file to track changes to the package.
