v1.2.1

Version - 1.2.1

Makes enum-typed response fields tolerant of values the server sends that this
SDK version does not yet list.

Changed

• Response enum fields are now open. A value the API returns that is not in
  this SDK's generated enum list (for example a new sourceResolution tier or a
  new status) is preserved as the raw String instead of raising and failing
  the whole response. Known values still decode to their typed enum member, and
  an absent optional field stays nil. Affects the enum fields returned by
  manage_videos (get_media, list_media, updated_media,
  updated_source_access, updated_mp4_support, get_media_clips,
  list_live_clips, track add/update/generate, direct-upload create/list/cancel),
  playback playback-ID responses, and playlist.get_playlist_by_id.

  A response enum field can therefore be either the enum member or a String.
  Guard before calling enum-only methods:

  r = media.source_resolution
  r.respond_to?(:serialize) ? r.serialize : r   # String when the value is unknown

• Request and input models are unchanged — their enum fields still accept only
  known members, so typos are caught before a request is sent.
