Contentful has updated its Markdown editor, introducing features such as markup highlighting, full-screen mode, media embedding, and keyboard shortcuts to improve the writing experience and simplify content transfer. The update follows the GitHub-flavored Markdown specification and aims to provide a more accessible and user-friendly way for authors to format their text. Unlike Rich Text formatting, Markdown is a plain text formatting syntax that allows for simple and non-intrusive markup, making it easier to process and display content across different platforms. The update is part of Contentful's efforts to prioritize the writing experience and provide a flexible API and stable infrastructure, and it builds on the growing popularity of Markdown as a default markup language used by various CMS and websites.
