Forma 36 v4 has been released by Contentful, offering a range of improvements and new features including enhanced accessibility, updated component structure, and improved developer experience. The main focus was on bringing critical accessibility improvements to the React components, achieving WCAG level AAA compliance in all components. This release also includes changes to how components are built, with separate packages for individual components, reducing bundle size and improving performance. Additionally, the developer experience has been enhanced through the introduction of Emotion, making it easier to work with Forma 36 components without additional CSS files. To facilitate a smooth migration, codemods are available for most components, and detailed guides have been provided for those that cannot be migrated automatically.
