-## Development
+## 0.3.0.99 (dev version)
 
-Bugs:
+New features:
+
+- `tinyplot(..., file = "*.pdf")` will now default to using `cairo_pdf()` if
+  cairo graphics are supported on the user's machine. This should help to ensure
+  better fidelity of (non-standard) fonts in PDFs. (#311 @grantcdermott)
+
+Bugs fixes:
 
-* The `cex` argument should be respected when using `type="bg"`. Thanks to @rjknell for report #307.
+- The `cex` argument should be respected when using `type="bg"`. Thanks to
