(feature request https://github.com/adamlilith/fasterRaster/issues/137 -- thank you, @JacobusS!) \no Updated citation to peer-reviewed journal article \n\n### Bug fixes\no `app()` is more robust. Previously, short raster could have caused improper function. (issue https://github.com/adamlilith/fasterRaster/issues/138 -- thank you, @laurapoggio-sptools!) \no `bioclims()` properly calculates progress bar width so you know how long you have to go get a coffee. \no `resample()` correctly calculates number of rows in output raster.
