Plunkr Case (Bug Reports)
I don't think it's necessary.

Current behavior
The callback function onChange doesn't receive the original event.

Expected behavior
The callback function onChange receive the original event.

Minimal reproduction of the problem with instructions
Add a p-checkbox, set the onChange function and check the parameters.

What is the motivation / use case for changing the behavior?

1. Access to originalEvent to call the special functions like: stopPropagation / eventPrevendDefault
2. To have the same behaviour on every input, like: https://github.com/primefaces/primeng/issues/1571 , https://github.com/primefaces/primeng/issues/1581

• Angular version: 8.X.X

• PrimeNG version: 8.X.X

@cagataycivici This was a breaking change and it was not mentioned as such...
You should not bump a minor version with breaking changes...
And the binary input now does nothing, we always receive an object instead of simple boolean now.
