EDIT: It appears Defraggler has similar breakage as well, the portable build is listed but redirects to the home page. <a href="https://www.ccleaner.com/defraggler/builds" rel="external nofollow">https://www.ccleaner.com/defraggler/builds</a>
don't these questions regarding links on the Builds page, especially for the Portable build, crop up every time a new version is released? (certainly feels that way)
It's usually that the download just fails to work, but this time Portable isn't even available it's just the Standard build which is visibly available.
