Netlify has released several updates in January 2021, including a new Next.js on Netlify one-click install feature, Rust support, and improved build plugins. The company also introduced new events called onSuccess and onEnd for Build Plugins, allowing users to automate more of their DevOps workflow. Additionally, Netlify has made improvements to its DNS management, forms, and documentation, as well as added features such as faster builds, better logs for failed deploys, and a Jamstack Explorers learning hub. The updates aim to make it easier for developers to build and deploy web applications with server-side rendering and live preview mode on Netlify.
