+## 1.17.1 - 2021-03-01
+
+### Added
+
+- Implementation of the Excel `AVERAGEIFS()` functions as part of a restructuring of Database functions and Conditional Statistical functions.
+- Support for date values and percentages in query parameters for Database functions, and the IF expressions in functions like COUNTIF() and AVERAGEIF(). [#1875](https://github.com/PHPOffice/PhpSpreadsheet/pull/1875)
+- Support for booleans, and for wildcard text search in query parameters for Database functions, and the IF expressions in functions like COUNTIF() and AVERAGEIF(). [#1876](https://github.com/PHPOffice/PhpSpreadsheet/pull/1876)
+- Implemented DataBar for conditional formatting in Xlsx, providing read/write and creation of (type, value, direction, fills, border, axis position, color settings) as DataBar options in Excel. [#1754](https://github.com/PHPOffice/PhpSpreadsheet/pull/1754)
+- Alignment for ODS Writer [#1796](https://github.com/PHPOffice/PhpSpreadsheet/issues/1796)
+- Basic implementation of the PERMUTATIONA() Statistical Function
+
+### Changed
+
+- Formula functions that previously called PHP functions directly are now processed through the Excel Functions classes; resolving issues with PHP8 stricter typing. [#1789](https://github.com/PHPOffice/PhpSpreadsheet/issues/1789)
+
+  The following MathTrig functions are affected:
+  `ABS()`, `ACOS()`, `ACOSH()`, `ASIN()`, `ASINH()`, `ATAN()`, `ATANH()`,
+  `COS()`, `COSH()`, `DEGREES()` (rad2deg), `EXP()`, `LN()` (log), `LOG10()`,
+  `RADIANS()` (deg2rad), `SIN()`, `SINH()`, `SQRT()`, `TAN()`, `TANH()`.
+
+  One TextData function is also affected: `REPT()` (str_repeat).
+- `formatAsDate` correctly matches language metadata, reverting c55272e
+- Formulae that previously crashed on sub function call returning excel error value now return said value.
+  The following functions are affected `CUMPRINC()`, `CUMIPMT()`, `AMORLINC()`,
+  `AMORDEGRC()`.
+- Adapt some function error return value to match excel's error.
+  The following functions are affected `PPMT()`, `IPMT()`.
+
+### Deprecated
+
+- Calling many of the Excel formula functions directly rather than through the Calculation Engine.
+
+  The logic for these Functions is now being moved out of the categorised `Database`, `DateTime`, `Engineering`, `Financial`, `Logical`, `LookupRef`, `MathTrig`, `Statistical`, `TextData` and `Web` classes into small, dedicated classes for individual functions or related groups of functions.
+
+  This makes the logic in these classes easier to maintain; and will reduce the memory footprint required to execute formulae when calling these functions.
+
+### Removed
+
+- Nothing.
+
+### Fixed
+
+- Avoid Duplicate Titles When Reading Multiple HTML Files.[Issue #1823](https://github.com/PHPOffice/PhpSpreadsheet/issues/1823) [PR #1829](https://github.com/PHPOffice/PhpSpreadsheet/pull/1829)
+- Fixed issue with Worksheet's `getCell()` method when trying to get a cell by defined name. [#1858](https://github.com/PHPOffice/PhpSpreadsheet/issues/1858)
+- Fix possible endless loop in NumberFormat Masks [#1792](https://github.com/PHPOffice/PhpSpreadsheet/issues/1792)
+- Fix problem resulting from  literal dot inside quotes in number format masks. [PR #1830](https://github.com/PHPOffice/PhpSpreadsheet/pull/1830)
+- Resolve Google Sheets Xlsx charts issue. Google Sheets uses oneCellAnchor positioning and does not include *Cache values in the exported Xlsx. [PR #1761](https://github.com/PHPOffice/PhpSpreadsheet/pull/1761)
+- Fix for Xlsx Chart axis titles mapping to correct X or Y axis label when only one is present. [PR #1760](https://github.com/PHPOffice/PhpSpreadsheet/pull/1760)
+- Fix For Null Exception on ODS Read of Page Settings. [#1772](https://github.com/PHPOffice/PhpSpreadsheet/issues/1772)
+- Fix Xlsx reader overriding manually set number format with builtin number format. [PR #1805](https://github.com/PHPOffice/PhpSpreadsheet/pull/1805)
+- Fix Xlsx reader cell alignment. [PR #1710](https://github.com/PHPOffice/PhpSpreadsheet/pull/1710)
+- Fix for not yet implemented data-types in Open Document writer [Issue #1674](https://github.com/PHPOffice/PhpSpreadsheet/issues/1674)
+- Fix XLSX reader when having a corrupt numeric cell data type [PR #1664](https://github.com/phpoffice/phpspreadsheet/pull/1664)
+- Fix on `CUMPRINC()`, `CUMIPMT()`, `AMORLINC()`, `AMORDEGRC()` usage. When those functions called one of `YEARFRAC()`, `PPMT()`, `IPMT()` and they would get back an error value (represented as a string), trying to use numeral operands (`+`, `/`, `-`, `*`) on said return value and a number (`float or `int`) would fail.
