Hugo 0.20 has been released, bringing a new set of features that can be easily utilized by users on Netlify, allowing them to install specific versions of Hugo without waiting for the company's update process. Previously, users had two options: wait for Netlify to install the version or manually add it to their repository. Now, users only need to set an environment variable `HUGO_VERSION` with the desired version number to use a new version on Netlify. This change also utilizes Deploy Contexts, which can be used to test with a specific version of Hugo without affecting production sites. Additionally, this update is part of Netlify's commitment to Open Source and showcases their Binrc program that automates downloading release files from GitHub.
