2.3.1

Fixed

• Fixed an issue where expression names were not allowed to start with a cell
  reference. #1058
• Fixed an issue where expression names were allowed to start with R1C1-notation
  references. For better compatibility with other spreadsheet software, strings
  such as R4C5, RC1000, R1C or RC can't be used in expression names
  anymore. #1058
• Fixed an issue where using reversed ranges with absolute addressing could
  cause the Incorrect array size error. #1106
• Fixed an issue where removing a sheet (removeSheet()) without clearing it
  (clearSheet()) could cause an error. #1121

2.3.0

Added

• Exported the ArraySize class as a public API. #843
• Renamed an internal interface from ArgumentTypes to FunctionArgumentType, and exported it as a public API. #1108
• Exported ImplementedFunctions and FunctionMetadata as public APIs. #1108

2.2.0

Added

• Added an American English (enUS) language pack. It's a convenience alias: it contains the same translations as the existing British English (enGB) language pack. #1025

Fixed

• Fixed functions VLOOKUP and HLOOKUP to handle duplicates in the way specified by the OpenDocument standard. #1072
• Fixed the MATCH function to handle descending ranges in the way specified by the OpenDocument standard. #1063

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

Added

• Added support for the array arithmetic mode in the calculateFormula() method. (#782)
