In that case the user notices (D). We can improve this doing (E), because now the user will experience (F), which is more desirable." Please fill in A-F accordingly. In particular your changelog is missing 'B' and 'D': what exactly is a 'resource_size_t overflow' and what does the user notice from it? Your changelog is also missing 'F'.
