2.1.0

Added

• Added two new functions: MAXIFS and MINIFS. #1049

Changed

• Changed the rounding strategy of the default time-parsing function to be independent of the timeFormats configuration option. Now, time values are always rounded to the nearest millisecond (0.001 s). #953

Fixed

• Fixed a rounding issue that caused the TEXT function to incorrectly convert dates and times to strings. #1043
• Fixed an issue where functions SUMIF, SUMIFS, COUNTIF, COUNTIFS, and AVERAGEIF incorrectly handled complex numeric values. #951

Removed

• Removed all polyfills from the CommonJS build and the ES modules build. In the UMD build, kept only the polyfills required by the supported browsers. #1011

2.0.1

Changed

• Changed the following npm scripts (used internally): docs, docs:api, docs:dev, docs:build, coverage, typings:check. #977

Fixed

• Fixed an issue where it was impossible to add a custom function with no parameters. #968

2.0.0

• Breaking change: Removed the deprecated gpujs and gpuMode configuration options. #812

Fixed

• Fixed an issue where the RATE function didn't converge for some inputs. #905

1.3.1

Fixed

• Fixed an issue where warnings about deprecated configuration options were getting duplicated. (#882)

1.3.0

Added

• Added a new static property: defaultConfig. (#822)

1.1.0

Changed

• Deprecated the binarySearchThreshold configuration option, as every search of sorted data always uses binary search. (#791)

Added

• Added support for the array arithmetic mode in the calculateFormula() method. (#782)
• Added a new CellType returned by getCellType: CellType.ARRAYFORMULA. It's assigned to the top-left corner of an array, and is recognized by the isCellPartOfArray() and doesCellHaveFormula() methods. (#781)

Fixed

• Fixed an issue with searching sorted data. (#787)
• Fixed the destroy method to properly destroy HyperFormula instances. (#788)

1.0.0

Changed

• Breaking change: Changed API of many sheet-related methods to take sheetId instead of sheetName as an argument. #645

• 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:

before	after
matrixColumnSeparator	arrayColumnSeparator
matrixRowSeparator	arrayRowSeparator

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

before	after
matrixMapping	arrrayMapping
isCellPartOfMatrix	isCellPartOfArray

• Breaking change: Changed Exceptions #747:

before	after
SourceLocationHasMatrixError	SourceLocationHasArrayError
TargetLocationHasMatrixError	TargetLocationHasArrayError

• 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
