The following text is taken from some company's press release (names removed to protect the innocent):

Application security has been strengthened by adjusting the minimum requirements for PINs and passwords within The <product name>® <Version>....

IMHO, when it comes to application security, adjusting the minimum requirements for PINs and passwords will not change the security of the application. It might make it more difficult to unauthorized individuals the gain access to the UI, but definitely it will not change the security state of the application.
