Inside some folders is an .htaccess file that lists certain *permitted* filetypes which may be accessed. (Anything else is blocked to prevent abuse on your site).
The side effect of this is that if you choose to use media types that are not already listed in the *permitted* list, then your visitors will not be able to see those resources.
Thus, if you are using product images that are not in the list of permitted types in your /images/.htaccess, you will need to add those types to the list.
Similarly, if you are using certain media types in music product previews, you will need to make sure those are in your /media/.htaccess.
And, if you are using filetypes for downloadable products that are not already listed in your /pub/.htaccess and /download/.htaccess you will need to add those as well.
For a listing of what is new in this release, please see the whatsnew_1.5.0.html file in the /docs folder.
