ANN: Leo 4.0 beta 3 outlining editor

Discussion in 'Python' started by Edward K. Ream, Oct 9, 2003.

  1. Leo 4.0 beta 3 is now available at: http://sourceforge.net/projects/leo/

    This is the third public release of Leo 4.0. There are no known serious bugs
    in
    this version of Leo. This will likely be the last beta release before 4.0
    final.

    N.B. 4.0 introduces new file formats. Please make full backups of important
    files.

    Highlights of 4.0 beta 3
    ------------------------
    - Fixed problems with setting Leo's window icons.
    - Plugins may now save their own information in <v> and <t> elements in .leo
    files.
    - The usual assortment of bug fixes and minor improvements.

    Quote of the month
    ------------------
    I've written documentation in WordPerfert, Ventura, Word, PageMaker, and
    FrameMaker and even though they create wonderfully looking and useful
    documents, they've never been able to do what I've been looking for. HTML,
    compiled help files, and later PDF came closer, but still not there. I think
    I've found it in Leo, a way to make a "living" document. A document built
    out
    of discrete parts that can be re-organized on the fly to meet the needs of a
    varying audience...Being a convert for less than a day I've still got a lot
    to
    learn, but just the possibility of keeping system maintenance scripts in the
    IT
    manual is mind boggling. -- David Nichols

    Highlights of 4.0 beta 2
    ------------------------
    * Fixed several bugs:
    - Fixed problems with reading and writing 4.0 derived files.
    - Fixed several Unicode-related bugs.
    - Fixed a crasher in the Go To Line Number command.
    - Fixed a problem with Importing Python files.
    * Important improvements:
    - Added allow_clone_drags setting that allows Leo to be used with Aqua.
    - When running Python 2.3 Leo can now create window icons without
    third-party packages.
    - The usual minor improvements and bug fixes.

    Highlights of 4.0 beta 1
    ------------------------
    * Improved and simplified format of derived files.
    - Eliminated child indices, extraneous blank lines and @body sentinels.
    - Eliminated @node sentinels that indicate outline structure.
    - New @nl and @nonl sentinels indicate where newlines are and aren't.
    - These changes largely eliminate unwanted cvs conflicts.
    * Greatly improved error handling.
    - Reading derived files _never_ alters outline structure or links.
    - Read errors leave the outline completely unchanged.
    - Broken clone links are gone forever.
    - As a result, using 4.0 is much safer than all previous versions.
    * Full compatibility will previous versions of Leo.
    - Leo reads all derived files properly, regardless of version.
    - Leo writes new-format derived files by default, and this default may be
    changed.
    * New commands:
    - Write 3.x Derived File and Write 4.x Derived File commands.
    - Import Derived File command.
    - Clear Recent Files command.
    * Several new plugins.
