This is a major release in which many new features have been included. We have introduced support for generating a password protected PDF. In the past, many of our customers have reported issues with how to tell whether the Aspose.Slides license is applied properly in their application. To help them, we have introduced support for verifying if the license is properly applied and even resetting it. We have also introduced support for using custom fonts without installing them from a predefined location. For more details about this feature, please read about custom fonts in our documentation section. We have also resolved many presentation cloning, and presentation and slide rendering issues in this release. The API’s overall rendering performance has been improved as well.
