 This document describes breaking changes of `teloxide` crate, as well as the ways to update code.
 Note that the list of required changes is not fully exhaustive and it may lack something in rare cases.
 
+## 0.10 -> 0.11
+
+### core
+
+Requests can now be `.await`ed directly, without need of `.send()` or `AutoSend`.
+If you previously used `AutoSend` adaptor, you can safely remove it.
+
+`File`'s and `FileMeta`'s fields now don't have `file_` prefix.
+If you previously accessed the fields, you'll need to change remove the prefix:
+
+```diff
+-_ = file.file_size;
++_ = file.size;
+```
+
+`Animation`, `Audio`, `Document`, `PassportFile`, `PhotoSize`, `Video`, `VideoNote` and `Voice` now contain `FileMeta` instead of its fields.
+Together with rename of `FileMeta`'s fields, you'll need to change `_` to `.`:
+
+```diff
+-_ = animation.file_size;
++_ = animation.file.size;
+```
+
+Message id fields and parameters now use `MessageId` type, instead of `i32`.
+You may need to change code accordingly:
+
+```diff
+-let id: i32 = message.id;
++let id: MessageId = message.id;
+```
+```diff,rust
+let (cid, mid): (ChatId, i32) = get_message_to_delete_from_db();
+-bot.delete_message(cid, mid).await?;
++bot.delete_message(cid, MessageId(mid)).await?;
+```
+
+Note that at the same time `MessageId` is now a tuple struct.
+If you've accessed its only field you'll need to change it too:
+
+```diff,rust
+-let MessageId { message_id } = bot.copy_message(dst_chat, src_chat, mid).await?;
++let MessageId(message_id) = bot.copy_message(dst_chat, src_chat, mid).await?;
+save_to_db(message_id);
+```
+
+Because of API updates `Sticker` type was refactored again.
+You may need to change code accordingly.
+See `Sticker` documentation for more information about the new structure.
