QuantLibXL and ObjectHandler version 0.8.0 have been released and are available for download:
Integration of a generic C++ library such as QuantLib into spreadsheets and other end user tools requires a standalone ObjectHandler component, a repository allowing objects to be stored, shared, updated, interrogated, and destroyed.
QuantLibAddin implements an interface supporting a subset of QuantLib functionality. Constructor, member and utility functions are defined in XML metadata from which Python application gensc generates source code for supported platforms including Microsoft Excel and OpenOffice.Org Calc.
QuantLibXL is the implementation of QuantLibAddin for Microsoft Excel. The QuantLibXL project includes a binary release comprising a compiled Addin and related spreadsheets.
