  - Changed the type of the field `photos` in `userProfilePhotos` to a list of `userProfilePhoto` instead of
    a list of `photo`. `getUserProfilePhotos` now returns a date for each profile photo.

* Added the possibility to get a Telegram Passport authorization form before asking the user for a password:
  - Removed the parameter `password` from the method `getPassportAuthorizationForm`.
  - Moved the fields `elements` and `errors` from the class `passportAuthorizationForm` to
    the new class `passportElementsWithErrors`.

  - Added the fields `base_language_pack_id`` to the class `languagePackInfo`. Strings from the base language pack
    must be used for untranslated keys from the chosen language pack.
  - Added the fields `plural_code`, `is_official`, `is_rtl`, `is_beta`, `is_installed`, `total_string_count`,
    `translated_string_count`, `translation_url` to the class `languagePackInfo`.

  Previously the size was included into the value of the `database_size` field.
* Added the field `language_pack_database_size` to the `storageStatisticsFast` class which contains the size of the
  language pack database.
* Added the field `is_support` to the class `user` which can be used to identify Telegram Support accounts.
* Added the class `HttpUrl` encapsulating an HTTP URL.
* Added the method `getMessageLink` which can be used to create a private link (which works only for members) to
  a message in a supergroup or channel.

  - Added the method `getChatStatisticsUrl` which returns a URL with the chat statistics.
* Added support for server-side peer-to-peer calls privacy:
  - Added the class `userPrivacySettingAllowPeerToPeerCalls` for managing privacy.
  - Added the field `allow_p2p` to `callStateReady` class which must be used to determine whether
    a peer-to-peer connection can be used.
* Added the option `ignore_background_updates` which allows to skip all updates received while the TDLib instance was
  not running. The option does nothing if the database or secret chats are used.
* Added the read-only option `expect_blocking`, suggesting whether Telegram is blocked for the user.
* Added the read-only option `enabled_proxy_id`, containing the ID of the enabled proxy.
* Added the ability to identify password pending sessions (where the code was entered but not
  the two-step verification password) via the flag `is_password_pending` in the `session` class.
  TDLib guarantees that the sessions will be returned by the `getActiveSessions` method in the correct order.
* Added the classes `JsonValue` and `jsonObjectMember` which represent a JSON value and
  a member of a JSON object respectively as TDLib API objects.

* Added the methods `getApplicationConfig` and `saveApplicationLogEvent` to be used for testing purposes.
* Added the temporarily class `databaseStatistics` and the method `getDatabaseStatistics` for rough estimations of
  database tables size in a human-readable format.
* Made the method `Client.Execute` static in .NET interface.
* Removed the `on_closed` callback virtual method from low-level C++ ClientActor interface.
  Callback destructor can be used instead.
* Updated dependencies in the prebuilt TDLib for Android:
  - Updated SDK to SDK 28 in which helper classes was moved from `android.support.` to `androidx.` package.
  - Updated NDK to r19c, which dropped support for Android versions up to 4.0.4, so the minimum supported version is
    Android 4.1.
  - Updated OpenSSL to version 1.1.1.
  - Added x86_64 libraries.
* Added out of the box `FreeBSD` support.
* Significantly improved TDLib compilation time and decreased compiler RAM usage:
  - In native C++ interface `td_api::object_ptr` is now a simple homebrew const-propagating class instead of
    `std::unique_ptr`.
  - Added the script `SplitSource.php`, which can be used to split some source code files before building
    the library to reduce maximum RAM usage per file at the expense of increased build time.
* The update `updateOption` with the `version` option is now guaranteed to come before all other updates.
  It can now be used to dynamically discover available methods.
* Added the ability to delete incoming messages in private chats and revoke messages without a time limit:
  - Added the parameter `revoke` to the method `deleteChatHistory`; use it to delete chat history for all chat members.
  - Added the fields `can_be_deleted_only_for_self` and `can_be_deleted_for_all_users` to the class `chat`
    which can be used to determine for whom the chat can be deleted through the `deleteChatHistory` method.
  - The fields `Message.can_be_deleted_only_for_self` and `Message.can_be_deleted_for_all_users` can still be used
    to determine for whom the message can be deleted through the `deleteMessages` method.
* Added support for server-generated notifications about newly registered contacts:
  - Setting the option `disable_contact_registered_notifications` now affects all user sessions.
    When the option is enabled, the client will still receive `messageContactRegistered` message in the private chat,
    but there will be no notification about the message.
  - `getOption("disable_contact_registered_notifications")` can be used to fetch the actual value of the option,
    the option will not be updated automatically after a change from another device.
* Decreased the maximum allowed first name and last name length to 64, chat title length to 128,
  matching the new server-side limits.
* Decreased the maximum allowed value of the `forward_limit` parameter of the `addChatMember` method from 300 to 100,
  matching the new server-side limit.
* Added protection from opening two TDLib instances with the same database directory from one process.
* Added copying of notification settings of new secret chats from notification settings of
  the corresponding private chat.
* Excluded the sponsored chat (when using sponsored proxies) from unread counters.
* Allowed to pass decreased local_size in `setFileGenerationProgress` to restart the generation from the beginning.
* Added a check for modification time of original file in `inputFileGenerated` whenever possible.
  If the original file was changed, then TDLib will restart the generation.
* Added the destruction of MTProto keys on the server during log out.
* Added support for hexadecimal-encoded and decimal-encoded IPv4 proxy server addresses.
* Improved the behavior of `changeImportedContacts` which now also deletes contacts of users without Telegram accounts
  from the server.
* Added the ability to call `getStorageStatistics` before authorization.
* Allowed to pass `limit` = -`offset` for negative offset in the `getChatHistory` method.
* Changed the recommended `inputThumbnail` size to be at most 320x320 instead of the previous 90x90.
* Disabled building by default of the native C interface. Use `cmake --build . --target tdc` to build it.
* Numerous optimizations and bug fixes:
  - Network implementation for Windows was completely rewritten to allow a literally unlimited number of
    simultaneously used TDLib instances.
  - TDLib instances can now share working threads with each other. Only a limited number of threads will be created
    even if there are thousands of TDLib instances in a single process.
  - Removed the restriction on the size of update or response result in JSON interface.
  - Fixed pinning of the 5th chat when there is a sponsored chat.
  - Fixed IPv6 on Windows.
  - Improved network connections balancing, aliveness checks and overall stability.
  - Various autogenerated documentation fixes and improvements.
