A screenshot of Mastodon's home timeline comparing the dark mode look in versions 4.2 and 4.3. The image is cut diagonally, revealing the new, dark mode with darker purple color on top and slightly lighter version on the bottom. The middle section with posts is also a bit wider. Not visible in the screenshot, but folks familiar with the design will notice a dark background inside the New Post input text field, which was previously white.
