😞 Well looks like I didn't test enough. When using 5.0.0 in my project I get...

Warning: ReactConfetti: getSnapshotBeforeUpdate() should be used with componentDidUpdate(). This component defines getSnapshotBeforeUpdate() only.

I can look in to fixing (probably just changing the functionality from getSnapshotBeforeUpdate to componentDidUpdate).

@alampros FYI. It's only a warning so probably not worth looking in to unpublishing 5.0.0. It could be asserted "it works but gives warnings that will be fixed in 5.0.1". The minor bummer might be that if the solution doesn't require 16.3 the 5.0.0 breaking change bump would have been unnecessary.
