Changes from Version 2.00 to Version 2.11:
------------------------------------------
Version 2.11 is a minor upgrade, intended mainly to provide 2.0
compatibility and support for various 2.0 features. It also fixes a couple
of bugs and inconsistences with some ARexx commands.
IMPORTANT: The preferences file format has changed.
'Liner had three bugs dealing with 2.0. Font support was poor (the
title bar would 'hang over' the text when using a large font, and fonts not
8 pixels wide would cause 'Liner to act weird when highlighting, moving the
cursor, etc.). The method by which the overscan screen size was determined
would cause problems if the user was using a large, scrollable Workbench
screen. Also, the file requestor, YAFR, had a problem determining what
devices were hooked up.
Version 2.11 has fixed the first two problems (overscan screen size is
now determined in a 2.0-friendly way, and _both_ vertical and horizontal
overscanning is supported), although a line will 'run off the end' if the
number of characters in that line is greater than the number of characters
that can be printed on one line in that font (e.g. if you're using a
640x200 screen and a font that can print 70 characters on that sized
screen, and try and have a line with more than 70 characters, problems will
occur). I've decided to let this go until the next version, when I plan to
incorporate word-wrapping into 'Liner and do away with "continuations"; it
will then be trivial to fix as opposed to now.
Version 2.11 incorporates several System 2.0 features. The 2.0 file
requestor is used (replacing YAFR, which takes care of the third bug),
along with 2.0 gadgets and menus. Not only does this give 'Liner that 2.0
(3D) look, it also reduces the size of 'Liner to 58K (version 2.00 was
74K).
There have been several changes regarding screen resolutions
supported. The "Screen Size" menu item is gone ('Liner just opens to the
Workbench screen size automatically), as is the "Interlaced" flag. There
is now a "Screen Type" menu item with six subitems: non-interlaced,
interlaced, productivity, productivity-interlaced, A2024 10Hz and A2024
15Hz (both 10Hz and 15Hz give the same screen resolution, but 15Hz has less
of the 'paneling' effect while scrolling than 10Hz, although it takes up
more bandwidth). There are three other subitems that let you choose the
display frequency: NTSC (60Hz, the default in North America), PAL (50Hz,
the default in most of the rest of the world), and Default (which uses
whatever the hardware default is for your machine). These two items only
have meaning when using non-interlaced or interlaced displays; the other
four by their nature default to your hardware defaults (this is taken care
of automatically when you switch to one of these modes). Also, the color
requestor will reflect the limited color choices available in the
productivity modes when 'Liner is in one of those modes.
That's about it. As always, any bug reports, etc. send to:
davids@ucscb.ucsc.edu or
davids@slugmail.ucsc.edu
or via regular mail (my address is in the normal documentation).
