Major Features

• Disable External Asset Loading in Emails: Added the ability to disable loading of external assets (images, stylesheets) when converting email files, improving security and conversion speed.

• Full Font Embedding for Word to PDF: Introduced support for embedding complete fonts when converting WordProcessing documents to PDF, ensuring consistent text rendering across all systems.

Public API and backward incompatible changes

1. Introduced SkipExternalResources and WhitelistedResources properties in the EmailLoadOptions class to control external asset loading during email conversion.

   To skip loading external resources during email conversion, set the SkipExternalResources property to true:

   var loadOptions = new EmailLoadOptions
   {
       SkipExternalResources = true
   };
   

   When SkipExternalResources is set to true, all external resources (images, CSS, etc.) will be blocked. To allow specific resources, add them to the WhitelistedResources list:

   var loadOptions = new EmailLoadOptions
   {
       SkipExternalResources = true,
       WhitelistedResources = { "trusted-domain.com", ".jpeg", ".png" }
   };
   

   Resources matching any entry in the whitelist will be loaded normally, while all other external resources will be skipped.

2. Introduced EmbedFullFonts property in the PdfConvertOptions class to embed complete fonts when converting WordProcessing documents to PDF.

   var convertOptions = new PdfConvertOptions();
   convertOptions.EmbedFullFonts = true;
