1.8.1

Fixes

• Make TVHTML5EMBEDDED's isEmbedded() getter return true.
• Fix possible recursion problem when loading track information from the Innertube API.
  • This likely only occurs if a client incorrectly has its isEmbedded method return false. Providing or omitting embedded client fields in the payload of embedded clients makes almost no difference to the response Innertube returns so additional provisions have been included to handle this to prevent these kinds of recursion issues in future.
