Jekyll 0.7.0 has been released and deployed to GitHub Pages, featuring support for SmartyPants through RDiscount for Markdown files. This update allows users to easily incorporate typographical elements such as curly quotation marks, em/en dashes, and ellipses by configuring their Jekyll repository's _config.yml file with specific settings. Once configured, users can push their repository to GitHub to automatically implement these enhancements. It's important to note that SmartyPants functionality is applicable only to pages composed in Markdown.
