 - remove `trend` parameter in `text()` method
 - change `text` parameter to `label`  in `text()`

-- add `plotter()` function, to scatter and plot at the same time (under request)
+- add `plotter()` function, to scatter and plot at the same time
 - add `simple_hist()` function, just like `simple_bar()`
 - change `colorize()` to output a `matrix_class()` object such that it can be inserted in `text()`, `indicator()` or any `label` parameter and any two objects can be easily summed as strings would. 
 - allow simple plots and fast image rendering to fit in subplots 
 - add matrix plot side bar 
+- make simple bar plots handle negative values
 - allow user to decide plot legend position and frame

 - solved issue [Issue 142](https://github.com/piccolomo/plotext/issues/142) by removing side symbol (like ⅃) in legend for single data set
