 #### Improvements 🧹
 
+- Dimensions can be set less than label dimensions [#1901](https://github.com/terrastruct/d2/pull/1901)
 - Boards no longer inherit `label` fields from parents [#1838](https://github.com/terrastruct/d2/pull/1838)
 - Prevents `near` targeting a child of a special object like grid cells, which wasn't doing anything [#1851](https://github.com/terrastruct/d2/pull/1851)
