Build 3.0.0.47 of xlsgen is a fix pack. It has the following :

- calc engine fix : an expression such as =3*A1:A10 stops returning a vector unless it's expressed in the context of an array formula (i.e. {=3*A1:A10}). Such function now returns a literal. This change is to comply with Excel behavior.

- exposure of vector shapes collection at the worksheet and chart levels. It is now possible to read and inspect existing vector shapes from a XLS or XLSX file.
