  * MRG random now raises an error with a clear message when the passed shape
    contains dimensions with bad value like 0. (Frédéric B. reported by Ian G.)
- * "CudaNdarray[*] = ndarray" work in more case (Frederic B.)
- * "CudaNdarray[*] += ndarray" work in more case (Frederic B.)
+ * "CudaNdarray[*] = ndarray" works in more cases (Frederic B.)
+ * "CudaNdarray[*] += ndarray" works in more cases (Frederic B.)
  * We add dimensions to CudaNdarray to automatically broadcast more frequently.
    (Frederic B.)
  * theano.tensor.argsort that wrap numpy.argsort (Hani Almousli).
