How do I upgrade my existing LyX system to version 1.3.0? --------------------------------------------------------- One of the perennial bug bears of LyX users in the past has been that they have had to run Edit->Reconfigure when starting their new version of the code for the first time. Strange and wonderful things would often result if they forgot to do this, so LyX 1.3.0 now runs Edit->Reconfigure automatically the first time the program is run. If you have your own layout files, you may need to update them a little: - floats are now defined in the layout file, using the "Float"..."End" construct. In most cases, adding "Input stdfloats.inc" to your layout file is enough. - counters are also defined in the layout files, using the "Counter"..."End" construct. As for floats, adding "Input stdfloats.inc" is probably a good idea. And of course, if you upgrade from LyX 1.1.x, remember that since 1.2.0, you have to do the following changes: - all layout files should have a "DefaultStyle" entry - the "Latex" font style does not exist anymore. If you really need its functionality, consider using the "PassThru" keyword instead. The new layout format keywords are described in the Customization manual. If you have your own binding files (especially math.bind), you will have to update them - math-insert now takes a latex macro name as argument, so that "math-insert sqrt" should now be "\math-insert \sqrt" - math-greek-toggle is now gone, and should be replaced by explicit bindings like \bind "M-m g a" "math-insert \alpha" Build requirements ------------------ LyX's graphics handling system has changed substantially. If you do not have the JPEG library installed, you may need to install it before you can use the graphics capabilities of LyX. If you do not have the ImageMagick command-line tools installed, you will need to modify the default set up of LyX, or install them, in order to get previews of your document's graphics. Document transfer ----------------- LyX 1.3.0 uses an external python script, lyx2lyx, to import documents written using previous versions of LyX. All versions of LyX as far back as 0.12 are supported, so any klyx users still holding out for an alternative to xforms will finally be able to put their dinosaur to rest ;-) Of course, this means that you must have python (at least version 1.5) installed in order to use LyX 1.3.0 with your old documents. lyx2lyx also has the framework in place to be able to convert documents to an earlier format. However, these converters have not yet been written so older versions of LyX will NOT be able to read documents saved with LyX 1.3.0. If you were previously (in LyX 1.1.x) using the floatflt paragraph option to wrap text around a figure, it was necessary to modify this for LyX 1.2.0 manually, as described in the manuals. The feature has been re-implemented as "Floting figure" inset in 1.3.0. Old files will be converted automatically, but you may want to convert the 1.2.x-style ERT constructs with the native solution (see section 3.8 of the Extended Features manual). Since LyX 1.2.0, the babel package is loaded after the user-defined preamble (because some packages really need to be loaded before babel). If you relied, on babel being loaded before your own definitions, you can add an extra "\usepackage{babel}" statement at the beginning of your preamble. http://bugzilla.lyx.org/show_bug.cgi?id=315
