For example, we found a bug in how IPP collections were handled in CUPS 1.4.3 and earlier that required a minor API change in 1.4.4: we added a reference count to the ipp_t structure. This potentially caused a memory leak for existing programs that did not "delete" the ipp_t structure added to a collection, but fortunately their use is rare in CUPS-based programs, even today.
