What happened to arrays in this release:
void foo (Object[] a) {}
class Foo {}
void main ()
{
Foo[] b;
foo(b);
}
The above code fails with the following message:
main.d(54): Error: function main.foo (Object[] a) is not callable
using argument
types (Foo[])
main.d(54): Error: cannot implicitly convert expression (b) of type
Foo[] to
Object[]
Have I missed something, I can't find this in the changelog?
I don't remember if there was a bugzilla entry for it, but it's the
object slicing problem. The thing is, main() expects b to be an array of
Foo's. If foo() replaces one of the array elements with an Object, then
b is no longer an array of Foo's, and can crash.
I think it would be good if it's in the changelog, even if there is no
bugzilla entry for it.
It's the first dmd bug on the list:

I see, thanks. I was search for "array" on the changelog page.
