Build 3.0.0.42 of xlsgen fixes a problem related to reading XLSX files using a non-US Windows operating system.
By non-US Windows operating system is meant an OS whose default floating-point separators (thousands and decimal), are different than in US. Germany is one example.
The bug could lead to file corruption as well as various xlsgen calculation and rendering problems.
The bug was introduced in early March 2012 in the development code branch as part as fixing an international-related bug. It is now fixed.
No source code change needed.
