It is not meant that every version of tools, application, software etc can come with complete error fixing. Because, whatever the latest versions may be, still they have some unknown errors at the beginning of applications.
In such a way, Wordpress is very keen on announcing its latest error fixed versions for users convenient. Nevertheless, after launching the every updated version, there were some errors, which cannot be fixed.
