+
+* `Core`:
+  * Improvements in `Update.sourceUser` extension
+  * Add extension `PrivateChat.toUser`
+  * Builder methods of `TextSource`s (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

+    `additionalSubcontextInitialAction` to all triggers

+  * Fields of `OrderInfo` became nullable (fix of [#917](https://github.com/InsanusMokrassar/ktgbotapi/issues/917))
+  * Add default `toString` to `ChatType` (fix of [#919](https://github.com/InsanusMokrassar/ktgbotapi/issues/919))
+  * Fix of method in `CreateInvoiceLink` (merging of [#920](https://github.com/InsanusMokrassar/ktgbotapi/issues/920), made by [byteduck-exploit](https://github.com/byteduck-exploit))
