    1. Resolved issues related to regional/international settings on non-English Windows and Microsoft office (e.g. decimal point interpretation, solver add-in listing, etc.
      (blog: Issues reported with Spanish version of Excel )
    2. Resolved an issue related to MS Excel Solver 2010 which yield to sub-optimal calibration. This was due to a new default (introduced for Excel 2010) for Non-negative values constraints.
      (FAQ: The calibration with Excel 2010 Solver does not give optimal coefficients.)
    3. Fixed an issue related to missing first constraint (stable model check) in the Excel Solver Dialog Box. This issue related to a limitation on Excel Solver, but we added a workaround for it.
      (FAQ: Why does the calibration function in NumXL shows the constraint's rhs of 0.9999?)
