+## 1.2.0

+### Added
+- `dayContentRenderer` prop: You can control how each date cell is rendered be passing this function that excepts a date and returns what need to be rendered (#242, #384, #476)

However if you want to keep using date-fns versions older than 2.0.0, (minimum version is 2.0.0-alpha.1) you need to pass the following props to your component. ([See the reason here](https://blog.date-fns.org/post/unicode-tokens-in-date-fns-v2-sreatyki91jg/), also see [this table](https://date-fns.org/docs/format))
