Hi all,
All of my books except one are in LyX 1.4.2. The latest book is LyX 1.5.3. I'm
hoping to get a 64bit machine with 8GB of Ram, and use LyX 1.5.4.
I know that once you open and save a LyX 1.4.2 doc in 1.5.4, you can never go
back to 1.4.2. So my question is, do you think 1.5.4 will reformat my 1.4.2
documents in any way? Forewarned is forearmed.
If you get a new LyX, why not the more recent 1.5.5?
Anyway, it is possible to have several different LyX versions installed
on the same machine. This is how I test self-compiled unreleased v.1.6,
while having 1.5 as a backup. You may have to compile your own LyX
in order to do this. I recommend having the latest lyx installed as 'lyx',
while you also have a 'lyx-1.4' to be on the safe side.
A new LyX should not change your documents, only offer new stuff you
couldn't do before. Still, bugs can happen. For a book, keep an extra copy
that you never ever change. You can always open a copy of that in an old LyX
if you find you have to.
You can test; open a book in a new LyX, then produce postscript or pdf
and compare with your printed work. (Or with a stored pdf if you have that.)
Even if there is a change, the layout should still be acceptable. Unless
you have
layout tweaks like a manual page break. I guess you usually will find no
change at all.
Keep a PDF copy of any book you print. That way, you won't need LyX to
make more copies. Now, if you make changes you will have to use LyX,
but then you will probably have to check the layout again anyway so
software revisions shouldn't really matter.
