We have released FX Equation 5.005.4.
The main improvement in this version is a greatly improved handling of vertically aligned equations.
Previous releases of FX Equation 5 have struggled with aligning equations when there is a mixture of text and equations on a line. For the past six months we have been recommending that, if you wanted to align equations, you did not include any text sections.
V5.005.4 removes this limitation.
The new aligner follows the following rules
1. Any line which STARTS with an equation will have equals signs vertically aligned.
2. Text AFTER an equation will not affect alignment
3. When two equations are separated by text, only the first equation is vertically aligned.
4. Lines which START with text will not take part in the alignment
This seems to be the most intuitive way to handle vertical alignment and is certainly far superior to what earlier versions have been producing.
