Instead of rustc-1.0.0-beta-$triple.tar.gz, betas will be named rustc-beta-$triple.tar.gz. This will give betas a stable download URL, prevent old artifacts from accumulating in the dist server's root directory, and not require the website to be updated every beta. As a tradeoff, it will be harder to download previous betas because they will need to be located in the archives.
