+* Primary Quarto document detection only considers `.R`, `.Rmd`, and `.qmd` as
+  end-of-file extensions. Previously, a file with `.R` elsewhere in its name,
+  such as `.Rprofile`, was incorrectly considered. (#1106)

 * Use the public Connect server API endpoint `/v1/tasks/{id}` to poll task
   progress. (#1088)
