Changes---1.5 RC1 (Preview Version)

     * Aquamacs now handles paragraphs better that are stored as  
single lines in the buffer: these very long ``lines'' are shown as  
paragraphs, with words wrapped were appropriate. The wrap functions in  
the Options menu will use the new technique. As a result, line numbers  
shown in Aquamacs correspond to line numbers in the file. Also, word  
wrap will work better now with variable-width fonts. Syntax  
highlighting is now correct in all situations, because it is based on  
the line separation in the underlying file and not on what's displayed  
(`longlines-mode' is not used any longer; a new variable `word-wrap'  
controls the display-time word wrapping.) Code by Kim F. Storm, Chong  
Yidong, David Reitter.

     * The end of file lines (newlines) or paragraph endings in soft  
word wrapping can be visualized via Option / Show/Hide / Show Newlines  
(`global-show-newlines-mode').

     * Symbols in the fringes have been adapted to look less  
conspicuous. (These are the indicators to the left and right of text  
lines.) Code by Kim F. Storm.

     * The ``small left fringe'' setting in the Show/Hide menu works  
again as intended.

     * Automatic wrapping detection (hard word wrap = auto-fill,  
vs.~soft word wrap) improved. A new customization option `auto-word- 
wrap-default-function' may be used to configure the default, which is  
hard word wrapping.

     * Navigation in buffers (up/down) optimized and improved. This is  
also a new buffer-local mode (`visual-line-mode'), which is enabled  
globally (`global-visual-line-mode'). That's also what the ``vl'' mode  
line indicator stands for.

     * Command-Backspace will remove the whole visual line now (`kill- 
whole-visual-line'), while Command-Shift-Backspace will remove the  
entire buffer line (which may be a paragraph, when soft wrap is on).

     * Environment variables are imported again in most situations  
despite bugs in OS X / Emacs. This issue could cause LaTeX calls to  
fail. The *Messages* buffer contains helpful notices. Reported by  
Thomas S. Dye and others.

     * An issue where pressing M-Backspace (especially in the  
minibuffer) could lead to an error message has been resolved.

     * The Help menu (in ``Diagnose and Report Bug'') provides a way  
to start another Aquamacs Emacs instance without any personal  
customizations. This should be used to reproduce any potential bugs  
before reporting them.

     * LaTeX configuration (standard paths) simplified.

     * Auto Frame Styles are turned on automatically when the user  
chooses to retain frame settings (colors, fonts) for a mode or as a  
default.

     * Searching for keywords in the Help menu now includes the Emacs  
Manual and the Emacs Lisp Reference.

     * Structure of Help menu revised.

     * in SLIME (Lisp mode), the Aquamacs tabs work again. (`slime- 
header-line-p' now defaults to nil; customize this variable to revert  
to the old behavior.)

     * Internal change: Full-screen editing is now handled via the  
frame parameter `fullscreen'.

     * Further minor bug fixes.
