 # quarto (development version)
 
+- Add several new wrapper function (thanks, @parmsam, #192): 
+  - `quarto_list_extensions()` to list installed extensions using `quarto list extensions`
+  - `quarto_remove_extension()` to remove an installed extension using `quarto remove extensions`
+  - `quarto_update_extension()` to update an installed extension using `quarto update extensions`
+
 - `quarto_create_project()` offers better user experience now (thanks, @jennybc, #206, #153).
 
 - `quarto_preview()` gains a `quiet` argument to suppress any output from R or Quarto CLI (thanks, @cwickham, #232.)
