- `style.font: mono` to use a monospaced font for the text/label. See [docs](https://d2lang.com/tour/style/#font). [#1010](https://github.com/terrastruct/d2/pull/1010)

#### Improvements 🧹

- `dagre` layouts that have a connection where one endpoint is a container is much improved. [#1011](https://github.com/terrastruct/d2/pull/1011)
- `elk` layouts have less bends in the routes. [#1033](https://github.com/terrastruct/d2/pull/1033)
- `elk` layouts center nodes better. [#1028](https://github.com/terrastruct/d2/pull/1028)
- `elk` layouts have nicer margins between node boundaries and edges. [#1028](https://github.com/terrastruct/d2/pull/1028)
- `elk` layouts container contents are centered within. [#1038](https://github.com/terrastruct/d2/pull/1038)
- `elk` layouts container dimensions fit label. [#1038](https://github.com/terrastruct/d2/pull/1038)
- `sketch` draws connections with less roughness, which especially improves look of corner bends in ELK. [#1014](https://github.com/terrastruct/d2/pull/1014)
- CSS in SVGs are diagram-specific, which means you can embed multiple D2 diagrams on a web page without fear of style conflicts. [#1016](https://github.com/terrastruct/d2/pull/1016)
