ANN: Leo 4.3 final

[Edward K. Ream]

Leo 4.3 final is now available at http://sourceforge.net/projects/leo/

Leo 4.3 is here after almost five months of work.

The defining features of Leo 4.3:
---------------------------------
1. Leo now stores options in @settings trees, that is, outlines whose 
headline is '@settings'. When opening a .leo file, Leo looks for @settings 
trees not only in the outline being opened but also in various 
leoSettings.leo files. Users can create arbitrarily complex user options 
with @settings trees.

2. The Preferences command temporarily replaces the outline pane with an 
outline showing all the @settings trees in effect. The Preferences command 
also replaces the body pane with a "settings pane". This settings pane 
allows you to change the settings selected in the outline pane using 
standard gui widgets.

3. Leo now stores recent files information in .leoRecentFiles.txt files.

4. Leo's read/write code in leoAtFile.py has been rewritten to support 
user-defined tangling and untangling. This is a major cleanup of Leo's core.

5. Leo now contains an excellent Plugins Manager plugin. This plugin enables 
and disables plugins automatically and tells you everything you need to know 
about each plugin. This plugin also lets you download plugins from Leo's cvs 
site.

6. You can install third-party extensions in Leo's extensions directory. Leo 
will attempt to import such extensions from the extensions directory when 
normal imports fail. The distribution contains Python Mega Widgets in the 
extensions directory.

What people are saying about Leo
--------------------------------
"Another day, another breakthrough using Leo--now I realize Leo is the best 
URL bookmark manager there is. No more bookmarks menus or favorites lists 
inside the browser for me. With the @url directive I can just double click 
on the URL to open it in my browser. Leo lets me arrange the URLs in a 
hierarchy (or multiple hierarchies), attach notes to them, save clippings of 
things I read on the sites. It's sooo much better than anything the browsers 
have built in and it lets me easily use different browsers on different 
platforms and different machines (try that with the browsers' built-in 
bookmark managers)." -- Dan Winkler

"I am an amateur photographer. I use plain old 35mm. film for my pictures. 
Over the weekend, I used Leo to organize my lists of pictures. It is quite 
helpful--I can have separate nodes for pictures I have enlarged, as well as 
pictures I have submitted to our local camera club. Thanks!" -- Rich Reis

"Cloning is pure genius!... Leo's cloning facility, allows me to create 
several views on the CFA course material. My main view follows the 
prescribed study guide. Another view is organized like the textbooks. Yet 
another gives me a glossary of terms. And when I'm done, I'll have some nice 
libraries...I can re-use later in other projects." -- Michael Manti
