 # Changelog
 
+## 1.1.0
+
+### Added
+
+- `chunk($size, $preserveKeys = false)` splits the values into arrays of `$size`, like `array_chunk()`. The lazy one yields each chunk as soon as it is full, so a streamed source is never held whole; the eager one gives a list array for an array and a `Ds\Seq` for anything else. A size below 1 throws `InvalidArgumentException`.
