 # TelegramBotAPI changelog
 
+## 0.21.0 TelegramBotAPI 4.5
+
+* _**All `MessageEntity`'es now are replaced with `TextPart`**_
+* Added support of strikethrough and underline
+    * Added `UnderlineTextSource`
+    * Added `StrikethroughTextSource`
+    * Added support in `RawMessageEntity`
+* Added support of `MarkdownV2`
+* Now will not be thrown exception when there is income unknown type of `RawMessageEntity`. Instead of this will be
+created `RegularTextSource` with the same text
+* Fixed problem that usually string formatting did not trigger escaping of control characters
+* Actualized work with `pre` type of text - now it is possible to use `language` for formatting of text
+* Removed constructor of `TextMentionTextSource`, which was deprecated previously
+* All `TelegramMediaFile` instances now have field `fileUniqueId`, which represents `file_unique_id` field from API
+* Now `ChatPhoto` have two additional fields: `smallFileUniqueId` and `bigFileUniqueId`
+* Now any administrator object instance have `customTitle` nullable field
+* Added the new request `SetChatAdministratorCustomTitle` to manage the custom titles of administrators promoted by the
+bot.
+* Added the field `slowModeDelay` to the `ExtendedSupergroupChat` objects.
+
+* `CaptionedInput` now have extension `fullEntitiesList` which will return list of `TextPart` with `RegularSource`'s
+* `TextPart` added - it will be used as part of some text and can be not related to telegram bot
+* `MultilevelTextSource` was added - it is type of `TextSource`, which can have subsources as parts of this text
+* In all `TextSource`s all fields now are lazy for avoiding of potential risk for performance issues
+
 ## 0.20.0 MPP Migration
 
 * Time library change: `joda-time` -> `com.soywiz.korlibs.klock:klock`
