New Features (Requires Feature Pack 3 access):

• Introduced the PIVOTSUM function to be used instead of the SPARSESUM function when summing across dynamic dimensions (dimensions using dynamic ranges). It also simplifies summing across subdimensions. Please note that this function requires Service Release 7. Projects using PIVOTSUM will load in Service Release 6 also, but variables using the function will become undefined.

Improvements:

• Variable tooltips now show additional summary details for array values.
• Studio now allows restoring the permanent value of a single variable through the new Restore Permanent Value command available on the variable's shortcut menu.
• Studio now allows restoring permanent variables at the end of the simulation.
• Studio now gives a warning when using the Restore Permanent Variables command to avoid accidental loss of inputs to such variables.
• Commands for vertical text alignment are now available on the Format menu and on the Format toolbar.
• The Hide Auto Report and Unhide Auto Report commands are now available in the Symbol toolbar.
• Reorganized the commands in the Layout menu and in the Layout toolbar.
• It is now easier to detect unresolvable circularities in connection with series variable feedback structures. Several new error messages have been introduced for this purpose.
• When a worksheet area is dragged from an unsaved Excel document in an attempt to create an XLDATA-based variable, you now get a message box with information about the fact that XLDATA only works with Excel documents that are saved to disk.
• User selections in the Convert Surplus Slices to Shortcuts dialog are now remembered.
• Improved the logic concerning initial selections in the Go To dialog making it easier to locate all variables for a given filter selection.

Bug Fixes:

• Fixed a problem that sometimes caused Studio 8 Service Release 6 to terminate unexpectedly when using a project saved with an older Studio version. This problem occured for projects with diagrams containing a flow in or out of a submodel where the controlling flow variable was a child of the same submodel. Files that no longer can be opened in Studio 8 Service Release 6 due to this problem can now be opened.
• Fixed several problems to make Studio handle insufficient memory better.
• Fixed a problem that caused incorrect numbers to be displayed in the Elements column of the Equations Window and the Details Window for variables with dynamic dimensions (dimensions using dynamic ranges).
• Fixed a problem where a failure to calculate a variable with a complex definition involving huge arrays (evaluation stack too small) could cause calculation problems for other variables as well. Not only the variable causing the problem, but also the other variables, would report NAN values.
• Studio now provides better error messages when the SERIESRANGE, FIRSTSERIESRANGE, and LASTSERIESRANGE keywords are used prior to specifying the series resolution.
• Fixed a problem with the SORT and SORTIDX functions that prevented sorting vectors with dynamic dimensions (dimensions based on dynamic ranges).
• Fixed a problem that caused the FRAC function with three parameters to return an incorrect result if the last parameter was non-zero and an incorrect result unit if used with a point unit.
• Fixed a problem with the ^ and #^ operators that prevented use of index variables in the first operand unless the operand was unitless.
• Fixed a problem that prevented use of the DERIVN function with 2 parameters if an index variable based on a dynamic range was used in the first parameter.
• Fixed a problem that prevented use of the SPARSEVECTOR and SPARSESUM functions if an index variable based on a dynamic range was used in any of the parameters.
• Fixed a problem that prevented use of the SCAN functions with 4 parameters if an index variable based on a dynamic range was used in one of the three first parameters.
• Fixed a problem that prevented use of the ARRAVERAGE, ARRMAX, ARRMIN, ARRPRODUCT, ARRSTDEVP, ARRSTDEV, ARRSUM, CEIL, FRAC, FLOOR, INTEGER, ROUND, and TRUNC functions with 2 or 3 parameters if the first parameter used an index variable based on a dynamic range.
• Fixed a problem that caused series variables to use an incorrect resolution when the major interval of the simulation was explicitly set different to the series resolution of the project.
• Studio now sets all series variables involved in an unresolvable circularity to NAN.
• Fixed a problem that in some cases could cause Studio to terminate unexpectedly when trying to optimize with apply times outside the current simulation horizon.
• Fixed a problem that in some rare cases could cause Studio to terminate unexpectedly when trying to optimize with apply times set to "Stop".
• Fixed a problem that in some cases caused the text of axis labels to be clipped.
• Fixed a problem that prevented a paste of a variable shortcut from being properly cancelled. If the user chose to cancel the operation when asked to enable the features of Studio 8 Feature Pack 3, a variable would nevertheless be created.
• Fixed a problem that in some cases prevented changes to be reflected in the four new columns of the Connections Window that were introduced in Service Release 6.
• Fixed a problem that caused ampersands in project, component, and simulation names to be incorrectly displayed in the Project Explorer and the Project Information dialog.
