Release Notes

v.1.3.1 Changes:
- Fixed issue with incorrect grand-total non-lazy calculation for PivotData cube with exactly one dimension
- Improved internal performance for PivotData lazy totals calculation (1.5x)
- Drastically increased performance for PivotTable row/column totals calculation (10x+)
- Added build for .NET Standards 1.5 (now PivotData can be used from .NET Core 1.0 apps)

v.1.3.0 Changes:
- bugfix: incorrect last column/row sorting with PivotTable.PreserveGroupOrder option.
- added ListAggregatorFactory (ListAggregator) for accumulating all values from an input source (works like LINQ GroupBy).
- added VarianceAggregatorFactory (VarianceAggregator) for calculating variance, standard deviation (stdev), sample variance and sample stadard deviation.
- added ObjectMember that simplifies processing of custom data models (typed collections).
- added PivotDataHelper that provides utility methods for any IPivotData object: GetDimensionKeys and GetDimensionType.
- improved ConvertHelper.ConvertToDecimal method (now it supports all primitive number types) and added ConvertHelper.ConvertToDouble method.

v.1.2.6 Changes:
- introduced IPivotTable interface for alternative implementations/wrappers.
- added PivotTable.GetValue(ValueKey row, ValueKey col) method for key-based access to pivot table values; this signature can be used for getting sub-total values.
- added PivotTable.SortColumnKeysByRowKey and PivotTable.SortRowKeysByColumnKey methods for key-based sorting (useful for ordering by sub-total values).
