Mohammed,
The 2.0.5 version has fixed some bugs related to type checking.
It's possible that your code was not correct initially, but the
compiler now catches the problem, where in 2.0.3 and 2.0.4 it
let you do the wrong thing.
Would you mind sending an email with the 23 errors to this list?
Seeing the list of errors will let us determine which ones of
them fall in the above category, and which ones are indeed caused
by backward-incompatible changes.
