Changed

• Breaking change: Changed API of many sheet-related methods to take sheetId instead of sheetName as an argument. #645
• Breaking change: Removed support for matrix formulas ({=FORMULA}) notation. Engine now supports formulas returning array of values (instead of only scalars). #652
• Breaking change: Removed numeric matrix detection along with matrixDetection and matrixDetectionThreshold config options. #669
• Breaking change: Changed API of the following methods to take SimpleCellRange type argument: copy, cut, getCellDependents, getCellPrecedents, getFillRangeData, getRangeFormulas, getRangeSerialized, getRangeValues, isItPossibleToMoveCells, isItPossibleToSetCellContents, moveCells. #687
• Breaking change: Changed the AGPLv3 license to GPLv3.
• Breaking change: Removed the free non-commercial license.
• Breaking change: Changed behaviour of setCellContents so that it is possible to override space occupied by spilled array. #708
• Breaking change: Changed behaviour of addRows/removeRows so that it is possible to add/remove rows across spilled array without changing array size. #708
• Breaking change: Changed behaviour of addColumns/removeColumns so that it is possible to add/remove columns across spilled array without changing array size. #732
• Breaking change: Changed config options #747:

• Breaking change: Changed CellType.MATRIX to CellType.ARRAY #747
• Breaking change: Changed API methods #747:

• Breaking change: Changed Exceptions #747:

• Changed SWITCH function, so it takes array as its first argument.
• Changed TRANSPOSE function, so it works with data of any type. #708
• Changed the way how we include gpu.js making it even more optional #753
