:boom: add default init.el Doom is moving away from supporting direct modification of its source files, or private modules within Doom's source tree. Instead, customizations should be relegated to ~/.doom.d/ (or ~/.config/doom/, doom will respect XDG conventions if it sees this directory). As suchm a default init.el is now supplied, which will break your custom ~/.emacs.d/init.el! The quick fix: mkdir ~/.doom.d mv ~/.emacs.d/init.el ~/.doom.d/init.el ~/.doom.d/early-init.el is also available if you need to change crucial settings before Doom loads anything. init.el will still be loaded before any other module is.

(add-hook 'emacs-startup-hook #'doom|restore-startup-optimizations))
Move early-init.el to init.el (for now) Calling tool-bar-mode, menu-bar-mode or scroll-bar-mode from early-init.el seems to cause a 15-30% slowdown in startup time, possibly for loading the UI libraries early. Also, loading early-init.el eagerly from init.el causes a GC hit for Emacs 25/26 users. It's too early to use this optimization.
