# Changelog for circular


## Unreleased changes


## 0.3.1

-   Change monadic folds so that commutativity is not anymore required.
-   Provide `foldKM`, a fold over the last k elements on the stack.


## 0.3.0

-   Bugfix `take`.
-   Make functions more consistent (`fromVector` and `toVector` now both work on
    mutable stacks).
-   Sort functions.
-   Improve documentation.


## 0.2.0

-   Complete rewrite using mutable vectors. A monadic interface is required now,
    but it is much cleaner in every other sense.


## 0.1.1

-   Remove `mean`.
-   Add benchmark.
-   Many small improvements.
