: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.

:boom: revise hook/var fns naming convention (2/2) This is second of three big naming convention changes. In this commit, we change the naming conventions for hook functions and variable functions: 1. Replace the bar | to indicate a hook function with a -h suffix, e.g. doom|init-ui -> doom-init-ui-h doom|run-local-var-hooks -> doom-run-local-var-hooks-h 2. And add a -fn suffix for functions meant to be set on variables, e.g. (setq magit-display-buffer-function #'+magit-display-buffer-fn) See ccf327f8 for the reasoning behind these changes.

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.
