 # pkgdown (development version)
 
+* `init_site()` once again describes one copy per line, and now uses a better prefix when copying assets from pkgdown itself (#2445).
 * Very wide words are now automatically broken across lines and hyphenated (when possible) when they'd otherwise create a horizontal scrollbar on mobile (#1888).
 * The `repo.source.url` field no longer requires a trailing slash (#2017).
 * Anywhere you can use `_pkgdown.yml`, you can now use `_pkgdown.yaml` (#2244).
