It is exciting to see lots of RISC OS software receiving updates in recent months. The latest good news is version 3 of CDVDBurn. This stalwart now runs on all RISC OS machines which have RISC OS 5.24 or later installed.

The software supports a wide range of USV and S-ATA drives and can now write BD-R and BF-RE media.
 
An exciting new feature is the "Disc Extractor" feature which allows direct access to ISO9660/Joliet Format. There is also a verify feature to check new copies against the original ISO image.
 
There are generous discounts for owners of previous versions looking to update.
