According to the announcement, the new features in version 1.4 include:
- Support for inserting images in SVG, GIF, and PDF formats (yes, PDF)
- Improved Epub validation
- Search and other improvements in iOS and Android Apps
- a New counter object
- Better JS support
At a cost of 600 euros per year for a single-user license (after a 30 day free trial), it's fairly expensive when compared to free apps like Sigil or even paid apps like Oxygen (which costs $423), but then it again PubCoder's niche focus could justify the price. While there are many apps which can make fixed layout ebooks, PubCoder automates more of the process, bringing more features within reach of the less tach-savvy.
