When something is broken we'll obviously fix the source code as soon as possible, however whether that triggers a binary release depends on the severity of the problem, and whether there's any workarounds/temporary fixes.

However once we've got official releases out, not every bug fix will result in an immediate release (unless we're doing a spectacularly bad job at testing!) as we will instead batch fixes for the next patch release, the frequency of which will be determined by the size of the fix list/severity of the bugs etc., but you shouldn't be kept waiting too long.
