    <releaseNotes>v.1.4.2 changes:
- PivotTable now skips Key.Empty keys when calculates ColumnKeys/RowKeys (github issue #11)

v.1.4.1 changes:
- AverageAggregator (and SumAggregator) now returns null instead of zero if count=0 (like SQL AVG/SUM)

v.1.4.0 changes:
- added netstandard2.1 build
- added PivotData.ProcessDataAsync methods (available only in netstandard2.1 build)

v.1.3.8 changes:
- removed builds for legacy targets (only netstandard20 and net45 are included)
- PivotTable class: fixed issue with sort-by-value for single-measure that is FormulaAggregator
- PivotTable class: fixed issue with sort-by-value when aggregator value is IList (ListAggregator, ListUniqueAggregator)
- PivotTable class: added ability to set custom IComparer for values (ValuesComparer property)
- PivotData class: fixed issue in ValueKey comparison for numeric dimension keys (cases like int vs long).

v.1.3.7 changes:
- fixed PivotDataState serialization issue with Key.Empty
- PivotData class: XOR-based hash function for keys replaced with sum-based to avoid collisions
- performance optimization: less array allocations in PivotData.ProcessData method and PivotTable class

v.1.3.6 changes:
- added ModeAggregator (calculates value that appears most often)
- fixed issue with slow sub-totals calculation in some cases
- always use InvariantCulture for numbers parsing</releaseNotes>
