Scope notification settings are now properly synchronized between all devices and chat notification settings can be reset to their default values: - The `notificationSettings` class was split into `chatNotificationSettings` and `scopeNotificationSettings`. - Only two notification settings scopes are left: `notificationSettingsScopePrivateChats` which is responsible for default notification settings for private and secret chats and `notificationSettingsScopeGroupChats` for all other chats. - `updateNotificationSettings` was split into `updateChatNotificationSettings` and `updateScopeNotificationSettings`. - `setNotificationSettings` was split into `setChatNotificationSettings` and `setScopeNotificationSettings`. - `getNotificationSettings` was replaced with `getScopeNotificationSettings`. * Added the field `filter` to the `searchChatMembers` method to support searching among administrators, bots, restricted and banned members. * Added the ability to use synchronous requests and `setAlarm` before the library is initialized. * Added the ability to send requests that don't need authentication before the library is initialized.
