21.0.1

• Core:
  • Improvements in Update.sourceUser extension
  • Add extension PrivateChat.toUser
  • Builder methods of TextSources (like pre which returns PreTextSource) lost suppression of redundant inline
    due to its redundancy
  • Add mention builders for EntitiesBuilder with UserId as variant instead of User
• BehaviourBuilder:
  • Add support of several rounds for CombinedSubcontextInitialAction. Now it will try hard to execute all its
    SubAction while all actions will not be completed successfully OR all left actions will not complete with errors
