The FX Online Beta has been out for three weeks and we have just uploaded a version that adds three new features. FX Online is our new, mathematical web publishing system.
Add Audio To a Page
You can now add an audio file to any page you create. You can either use an existing file or record your own, dulcet tones to describe the concept on the page.

Arrows
We have also added a new, arrow tool that permits you to add quick arrows to your diagrams.

Example
You can see both of these new tools in action in the Introduction To FX Online example web lesson.
Web Preview
We have also added an option to preview how the page will appear in a web browser.

Using , For Decimal Points
The latest version also fixes an issue where a number of features where not working when used in locations which use , as the decimal point.
