@@ -10,6 +10,7 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
 ### Added
 
 - Added support for the new license key format. A proprietary key can now grant a subset of the library: a function your key does not include evaluates to a `#LIC!` error, and the matching parts of the API throw a `LicenseCapabilityMissingError`. `getAvailableFunctions()` and `getFunctionDetails()` describe only the functions your key includes. [#1728](https://github.com/handsontable/hyperformula/pull/1728)
+- Added new functions: RANK.EQ and its alias RANK. [#1786](https://github.com/handsontable/hyperformula/pull/1786)
