The following sections summarize the new functionality introduced in the library with links to the relevant documentation that describes how to use the new features.

## What Is New in 2024 Q4

* Introduced a timeout mechanism for import and export of documents. The new `Import` and `Export` methods for all format providers have a mandatory timeout parameter. See [PdfFormatProvider import and export timeout requirements](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/formats-and-conversion/pdf/pdfformatprovider/pdfformatprovider).

## What Is New in 2024 Q2

* Instead of using the `PdfExportSettings`.[ShouldEmbedFont](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/formats-and-conversion/pdf/pdfformatprovider/settings) property, use the `FontEmbeddingType` property to specify whether the full font or a subset is embedded in the document.
* Support for OTF (OpenType Font) font file format.

## What Is New in 2014 Q3

**New Features**
