- New api: `getQuerySuggestions`: Returns the suggestions youtube provides while making a video search.
|
||||
- Now playlists with more than 100 videos return all the videos. Thanks to @ATiltedTree.
|
||||
- Implemented `ChannelAboutPage`, check the tests their usage.
|
||||
- Implement filters for `search.getVideos`. See `filter` getter.
|
||||
|
||||
## 1.8.0
|
||||
- Fixed playlist client.
