Netlify has released Build Plugins, which allow users to automate build tasks, customize their build process, and make development easier by adding additional code to the netlify.toml configuration file or clicking the 'Install' button on the Build Plugins page. These plugins can be used to cache files, check for broken links, trigger testing, and more. The community has created numerous resources, including documentation, tutorials, and examples of how to use and create Build Plugins. Available plugins include those that look for accessibility failures, add Instagram, check for misspelled brand words, and trigger testing during deployment outside set hours. Additionally, the Netlify dashboard now lists a 'Plugins' page at the top, making it easy to access and manage Build Plugins.
