The new SDK features include Timeouts, Multiple Base URI Support, and Custom Exception Classes. The new feature of Timeouts allows developers to add retry mechanisms with specified timeout values to improve user experience and make applications more robust and reliable. Multiple Base URI Support enables developers to use the SDKs with their already configured environments without hassle, making it easier to separate out different parts of a project. Custom Exception Classes allow developers to define custom exception classes that provide more information about exceptions that occurred during development, enabling them to display error messages in a way that suits their needs. These features are designed to improve the developer's experience and provide value-added features with automatically generated SDKs.
