+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"

+------------------
+
+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.
