No, this Salesforce release does not impact Apsona PDF conversion functionality.
Salesforce introduced an update where the Apex Blob.toPdf() method now uses the same rendering service as Visualforce PDF rendering. This enhancement provides improvements such as additional fonts, multibyte character support, and changes the default font from sans-serif to serif.
However, after review with the engineering team, it was confirmed that Apsona’s PDF conversion tool does not use the Blob.toPdf() method for PDF generation. Since Apsona uses a different PDF conversion mechanism, no action or configuration changes are required from customers.
Even though the Salesforce rendering service behavior has changed, Apsona PDF merges and conversions continue to function normally because they are independent of the Blob.toPdf() implementation.
