+                    We’re excited to announce the release of Wave Terminal v0.8. This update introduces a brand-new
+                    layout engine, featuring drag-and-drop screen splitting with flexible block sizing and positioning.
+                    We've also integrated powerful tools like file previews, an editor, web integration, and AI, all
+                    designed to keep you focused and minimize context switching. And for the first time, Wave Terminal
+                    runs <b>natively on Windows</b>!
+                </div>
+                <div>
+                    Wave v0.8 is less opinionated, giving you the freedom to use your standard terminal prompt and
+                    command completions, while supporting all shells (not just bash/zsh). We've also improved
+                    compatibility with ohmyzsh packages, removing some of the friction users experienced. It’s faster,
+                    more performant, and provides a stronger foundation for you to build your own blocks and widgets in
+                    the future.

+                    settings, and configuration will <i>not</i> be carried over. If you'd like to continue to run the
+                    legacy version, you will need to download it separately.
