 ### Database nicknames
 
-[TODO]
+Users can now assign nicknames to their configured databases, making it easier to identify and organize connections. Instead of relying on technical database names, users can set meaningful labels that will be used througout Mathesar.
+
+![A screenshot of Mathesar's UI showing a list of grant proposal databases with clear nicknames.](../assets/releases/0.2.1/nickname-db-list.png)
+
+
+This is especially useful when managing multiple databases with identical names, or when connecting to external services where database names are automated.

 ### In-app feedback
 
-[TODO]
+Users can now provide direct feedback within the app using a built-in feedback form. This simple  input allows users to share thoughts, report issues, or suggest improvements without leaving the interface.

 ### Column widths are persisted
 
-[TODO]
+Column widths in table views are now automatically saved, ensuring a consistent layout across sessions. Users no longer need to manually adjust column sizes every time they revisit a table, improving usability and efficiency when working with columns of varied lengths.

 ### Drop schema contents when deleting
 
-[TODO]
-
+Mathesar now automatically drops all objects within a schema before deleting the schema itself, without relying on CASCADE. This ensures a safer and more controlled deletion process, preventing unintended removal of external dependencies while still allowing users to delete schemas that contain objects.
 
-It's new behavior for Mathesar.
-It's novel in the field, AFAIK. No other product (that I'm aware of) has the same combination of safety and convenience provided by this.
-It warrants a bit more description, since the difference between this and CASCADE may surprise or interest a knowledgeable user, and may make some more confident when letting their users use Mathesar to access the DB.
+![A screenshot of a table of grant allocations with customized column widths tailored to the data.](../assets/releases/0.2.1/schema-deletion.png)
 
+This strikes a unique balance between safety and convenience, making it easier to manage schemas while reducing the risk of accidental data loss. It also provides greater confidence when granting database access to users, as deletions remain contained and predictable.
