Vcomplete

• Support built-in completion enhancements introduced in Emacs 29.
  Built-in commands are now used when available. Completions are
  highlighted using built-in facilities when available.
  
• Function vcomplete-current-completion can now be called from anywhere and
  without any arguments (in which case point is used).
  
• Breaking changes
  
  • Macro vcomplete-with-completions-buffer has been replaced with
    Macro vcomplete-with-completions-window.
    This breaks the previously available Embark integration.
    
  • Option vcomplete-search-range is no longer used in Emacs 29+.
    
  • Function vcomplete-current-completion never throws a user error anymore.

• Now available on NonGNU ELPA.
  
• Remove Embark integration.
  Embark integration broke in a non-trivial way, so it has been
  removed due to a lack of interest in maintaining it. This
  integration is compatible with older versions of Embark (and will
  continue to be compatible with Vcomplete for versions before 2.0) so
  it is possible to install it manually from a previous release.

• Fix the completion list window still highlighting completions in
  some cases after vcomplete-mode is disabled.
  
• Improve Embark integration
  Fix Embark 'non-edit commands' not immediately exiting when
  vcomplete-auto-update is t. Add (auto loaded) vcomplete-embark-mode
  which enables Embark integration. It is no longer required to
  explicitly load vcomplete-embark.el to enable this integration.
  
• Add vcomplete-search-range.
  This custom variable is used to control in which frames the
  completion list buffer is searched for during completion.

• Add the vcomplete-highlight face.
  This face is used to highlight completions. By default, it is the
  same as the built-in highlight face.
  
• Add vcomplete-no-update-commands.
  This custom variable is used to control which commands shouldn't
  cause the completions list buffer to update.
  
• Embark support has been moved to a separate file.
  It must be loaded explicitly (using (require 'vcomplete-embark) or
  similar).

• Make auto updating the completion list buffer more responsive.
  
• Support commands which use completion-in-region in the minibuffer.
  
• Add basic Embark support.
  
• Highlight the completion at point in the completion list buffer even
  when using normal navigation commands.
  
• Remove vcomplete-kill-buffer.
  This was done as part of an effort to simplify the code base (since
  third party solutions to completion actions exist).
  
• Optionally automatically update the completion list buffer.
  See vcomplete-auto-update's documentation string for more
  information.
