+You can now type `@` in any document to insert an inline date mention. Just like mentioning a teammate or linking to another document, type `@` and start typing a date to place it right in the flow of your text. Date mentions are a natural way to reference deadlines, meetings, or milestones without breaking into a separate calendar app.
+
+You can use natural language like `@Today`, `@Yesterday`, relative dates like `@2 days ago`, or more formal formats like `@25-12-26`.

+
+We've shipped a round of improvements to task lists and checkboxes in the editor so they're easier to use and more natural to interact with.
+
+- **Quick conversion** – type `[ ]` at the start of any bullet list item to instantly convert it into a task list. Converting via the menu will now act more predictably
+- **Completion animation** – a stroke animation plays when you check off a task, giving a satisfying sense of progress
+- **Better "Hide completed"** – the option to hide completed tasks now applies correctly to the current list, rather than affecting parent list items
