-***Please do not use version 0.6.0. It does not support plotnine version 0.12.1.***

+#### 05162023: version 0.6.1 is released.
+- Patchworklib supported plotnine version 0.12.1. It may be the final support for plotnine due to the difficulty to trace the plotnine developments.
 - Bricks object gained the new methods `align_xlabels` and  `align_ylabels`, which help users align x/y labels of the given Brick object.
 - The new argument `equal_spacing` was added to the stack function. If this value is `True`, axes bounding-boxes should be placed with equal spacing between them. Otherwise, depending on the text values of x/y tick labels and x/y labels, they may not always be equally spaced.
 - Closed and maybe solved the issue ["Align labels of Bricks when subplot axes are aligned. #40"](https://github.com/ponnhide/patchworklib/issues/40)
