 - `quarto_path()` now correctly return `NULL` when no quarto is found in the PATH (thanks, @jeroen, #220, #221).
 
+- `.libPaths()` from the calling R session will now be passed by default to all call to quarto as a subprocess. This should solve issue with **pkgdown** or when building vignettes (thanks, )

 # quarto 1.4.4
 
 - `quarto_preview()` now looks at `quarto preview` log to browse to the correct url when inside RStudio viewer (thanks, @aronatkins, #167).
