** New global minor mode 'etags-regen-mode'.
This minor mode generates the tags table automatically based on the
current project configuration, and later updates it as you edit the
files and save the changes.
+++
** New package Which-Key
The 'which-key' package from GNU ELPA is now included in Emacs. It
implements the global minor mode 'which-key-mode' that displays a table
of key bindings upon entering a partial key chord and waiting for a
moment. For example, after enabling the minor mode, if you enter 'C-x'
and wait for one second, the minibuffer will expand with all available
key bindings that follow 'C-x' (or as many as space allows).

** New minor mode 'completion-preview-mode'.

using an inline preview. New user options in the 'completion-preview'

This provides a new minor mode, 'window-tool-bar-mode'. When this minor
mode is enabled, a tool bar is displayed at the top of a window. To
conserve space, no tool bar is shown if 'tool-bar-map' is nil. The
