# tuber 2.0.0

Released 2026-08-17.

## Breaking API cleanup

* List endpoints now use a consistent `list_*()` prefix. The renamed functions
  are `list_comments()`, `list_comment_threads()`, `list_playlist_items()`,
  `list_playlists()`, `list_subscriptions()`, `list_live_chat_messages()`, and
  `list_super_chat_events()`.
* Resource-specific names replace ambiguous names and abbreviations, including
  `get_video_stats()`, `get_channel_details()`, `list_popular_videos()`,
  `list_video_categories()`, `list_languages()`, and `download_caption()`.
* Singular mutation arguments use singular names, such as `video_id`,
  `comment_id`, and `playlist_item_id`. Plural ID arguments accept vectors.
* Public reads default to API-key authentication. OAuth-only functions no
  longer expose an `auth` choice.
* Simplified list results use fixed snake-case schemas. Set `simplify = FALSE`
  to retain the collected API response. `get_video_details()` remains dynamic
  because its columns depend on `part`.

See `vignette("api-conventions", package = "tuber")` for the full migration
table and endpoint support matrix.

## Correctness

* Video and caption uploads now use Google's resumable upload protocol.
  Thumbnail and channel-banner uploads use explicit media uploads and enforce
  YouTube's file-size limits.
* Comment collection fetches every reply page instead of relying on the reply
  preview embedded in a comment thread.
* Channel, playlist, subscription, comment, live-broadcast, and search wrappers
  now enforce the filter combinations documented by YouTube.
* Pagination treats `max_results` as a total limit and trims the first page as
  well as later pages.
* Quota estimates use Google's current data, search, and video-upload buckets
  and method-specific costs.
* The optional response cache covers reference data, is transparent and
  persistent when configured, and is isolated by authentication credentials.
* Removed wrappers for retired related-video and guide-category endpoints.

## Documentation

* Added an API convention and endpoint coverage vignette.
* Rewrote the README around the supported API and removed obsolete OAuth,
  caption, and TLS instructions.

# version 1.4.1

## Bug fixes

* `list_videocats()` and `list_guidecats()` appended the translated filter to
  the query list as an unnamed element, so the query contained an unnamed
  component. Both `httr` and `httr2` reject such a query ("All components of
  query must be named"), so neither function could issue a request at all. The
  filter is now merged by name, and `regionCode`/`id` reach the API.

  Note for `list_guidecats()` specifically: Google deprecated the
  `guideCategories` endpoint in September 2020 and it no longer returns data.
  The request is now assembled correctly, but the method it targets is gone, so
  this repairs the client rather than restoring the feature.

* `get_live_streams()` accepted `channel_id` and required either that or
  `stream_id`, then sent `channelId` alongside `broadcastStatus`.
  `liveBroadcasts.list` has no `channelId` parameter and accepts exactly one of
  `broadcastStatus`, `id` or `mine`, so a status-only query was impossible and
  the combinations it did send were invalid. It now takes exactly one filter,
  gains `mine`, and errors clearly on the rest.

* `get_comments(simplify = TRUE)` assigned the first comment's id to every row,
  because `raw_res$items[[1]]$id` is a scalar that R recycled over the frame.
  Two comments came back carrying the same id and the second was lost. It also
  sent `pageToken` and `maxResults` alongside a `comment_id` filter, which
  `comments.list` documents as unsupported with `id`.

* `list_videocats()` indexed its filter with `filter$regionCode`. `filter` is a
  named character vector, so this raised "$ operator is invalid for atomic
  vectors" on every call. `list_guidecats()` failed the same way when
  assembling its result: with no items it raised "replacement has 1 row, data
  has 0", and with items it returned a list rather than the documented
  `data.frame`. Both now index by name and return a `data.frame` in every case.

* `get_comments()` documented and validated a `page_token` argument but never
  placed it in the query, so paging through replies with a `parent_id` filter
  always returned the first page. It is now sent as `pageToken`.

* `list_regions()` and `list_abuse_report_reasons()` documented and validated an
  `hl` argument that never reached the query. Both `i18nRegions.list` and
  `videoAbuseReportReasons.list` support `hl`, and the sibling `list_langs()`
  already sent it. It is now sent.

* `get_live_streams()` sent its `status` filter as `eventType`, which is a
  `search.list` parameter. `liveBroadcasts.list` filters on `broadcastStatus`.

# version 1.0.1

* Fixed the cross-ref checks

# version 0.9.9.9000 (development version)

* Added support for API key authentication with two new exported functions, `yt_get_key()` and `yt_set_key()`, and a new `auth` argument to the internal function `tuber_GET()`. Users can now pass `auth = "key"` to any function that uses `tuber_GET()` to enable API key authentication. The behavior of `tuber_GET()` remains unchanged when using the new default, `auth = "token"`, which avoids breaking changes to previously written code (@gvelasq, #117).

# version 0.9.9

* added functionality like upload_video etc. see https://github.com/gojiplus/tuber/commit/2cf53c50e9079af0f6b1a478698d0bda15f4c5e0
