5. Icarus now treats post thumbnails and cover images separately. For any posts/pages with an thumbnail image, change thumbnail: to cover: in the front-matter:

   1 2 3 4 5

   title: Getting Started with Icarus date: 2020-04-01 - thumbnail: /gallery/covers/vector_landscape_1.svg + cover: /gallery/covers/vector_landscape_1.svg

   You can still set thumbnail in the front-matter to show a smaller thumbnail image for your posts in the archive page and in the recent post widget.
