-In general, you don't need to convert any documents saved with LyX
-1.1.5 or 1.1.6 to use them with LyX 1.2.0.
-
-Older versions of LyX cannot read documents saved with LyX 1.2.0.
-
-LyX 1.2.0 can read most documents saved with lyx 1.1.6 correctly.
-
-If you were previously using the floatflt paragraph option to
-wrap text around a figure, you will need to modify this for LyX 1.2.0
-manually, as described in the manuals. Please ask on the lyx-users
-list for assistance if you have trouble with this.
-
-Note that your document may rely on the floatflt package (for example,
-you may use \floatingfigure via LaTeX commands). If your document does
-not have "\usepackage{floatflt}" already in the user pre-amble, you will
-need to add it.

+LyX 1.4.x 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 1.5.2)
+installed in order to use LyX 1.4.x 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 only been written
+for the conversion from 1.4.x to 1.3.x, so versions of LyX older than
+1.3.0 will NOT be able to read documents saved with LyX 1.4.x.
+The conversion from 1.4.x to 1.3.x is lossless as long as no new features
+are used. lyx2lyx tries hard to find something equivalent for new
+features such as boxes, but this is known to fail sometimes.
+LyX 1.3.7 contains an updated lyx2lyx that can read documents in 1.4.x
+format. LyX 1.4.x can also export to 1.3.x format for document transfer to
+older 1.3.x releases.
+
+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
