Added

• Namespacing phase 2 - styles. PR #2471

• Improved support for passing of array arguments to Excel function implementations to return array results (where appropriate). Issue #2551

  This is the first stage in an ongoing process of adding array support to all appropriate function implementations,

• Support for the Excel365 Math/Trig SEQUENCE() function PR #2536

• Support for the Excel365 Math/Trig RANDARRAY() function PR #2540

  Note that the Spill Operator is not yet supported in the Calculation Engine; but this can still be useful for defining array constants.

• Improved support for Conditional Formatting Rules PR #2491

  • Provide support for a wider range of Conditional Formatting Rules for Xlsx Reader/Writer:

    • Cells Containing (cellIs)
    • Specific Text (containing, notContaining, beginsWith, endsWith)
    • Dates Occurring (all supported timePeriods)
    • Blanks/NoBlanks
    • Errors/NoErrors
    • Duplicates/Unique
    • Expression

  • Provision of CF Wizards (for all the above listed rule types) to help create/modify CF Rules without having to manage all the combinations of types/operators, and the complexities of formula expressions, or the text/timePeriod attributes.

    See documentation for details

  • Full support of the above CF Rules for the Xlsx Reader and Writer; even when the file being loaded has CF rules listed in the <extLst><ext><ConditionalFormattings> element for the worksheet rather than the <ConditionalFormatting> element.

  • Provision of a CellMatcher to identify if rules are matched for a cell, and which matching style will be applied.

  • Improved documentation and examples, covering all supported CF rule types.

• Add support for one digit decimals (FORMAT_NUMBER_0, FORMAT_PERCENTAGE_0). PR #2525

• Initial work enabling Excel function implementations for handling arrays as arguments when used in "array formulae" #2562

• Enable most of the Date/Time functions to accept array arguments #2573

• Array ready functions - Text, Math/Trig, Statistical, Engineering and Logical #2580

• Improved code coverage for NumberFormat. PR #2556
• Extract some methods from the Calculation Engine into dedicated classes #2537
• Eliminate calls to flattenSingleValue() that are no longer required when we're checking for array values as arguments #2590
