@@ -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: `TEXTBEFORE`, `TEXTAFTER`, `TEXTSPLIT`. [#1792](https://github.com/handsontable/hyperformula/pull/1792)

@@ -127,3 +127,5 @@ A few of the rows above share a root cause worth stating once:
 - **Rounding toward zero, not down.** `INT` discards the fractional part rather than rounding toward negative infinity, so it differs from Excel and Google Sheets for negative input only. `ROUNDDOWN`/`ROUNDUP` are unaffected — they are defined in terms of zero in all three.
 - **`ISEVEN`/`ISODD` do not truncate.** They test the remainder of the value as given, so a value with a fractional part returns `FALSE` from *both*. Excel and Google Sheets truncate to an integer first, so exactly one of the two is always `TRUE`.
 - **`CEILING.MATH`/`FLOOR.MATH` honour only `mode` = 1.** Excel and Google Sheets switch the negative-number rounding direction for any non-zero `mode`.
+- **`TEXTSPLIT` returns `#N/A` where Excel returns `#CALC!`** when `ignore_empty` is on and nothing is left after the split (`=TEXTSPLIT(",,", ",", , TRUE)`), because HyperFormula has no `#CALC!` error.
+- **`TEXTSPLIT` needs literal arguments to size its result.** The size of the spilled array depends on the text and the delimiters, and HyperFormula predicts it only when the text, the delimiters, `ignore_empty` and `match_mode` are literals (a number may carry a sign). With anything else, such as `=TEXTSPLIT(1+1, "")` or a cell reference, the formula is treated as returning one value and a longer result is `#VALUE!`, the same limitation as `SEQUENCE` with non-literal dimensions (`=SEQUENCE(1+1)`). Wrapped in another function, for example `=INDEX(TEXTSPLIT(A1, ","), 1, 2)`, it works for any argument.
