+In most cases the dialogs have been designed to make it impossible to input

+Power LaTeX users can still input obtuse "glue lengths", but the widgets are

 ** Math editor
 
-Andre??
+There have been few visible and some not-so-visible changes. On the
+visible side we have better visual feedback regarding the structure of
+a formula by showing the nesting by small purple decorations in the
+formula itself and by revealing the names of the nesting levels in the
+minibuffer. There is now native support for symbols from the wasy
+package containing e.g. the zodiac symbols. New is also the internal
+structure of font changes which are now proper "insets" as anything
+else from a square root to an array. This does not only simplify the
+code greatly but also allows the same editing tricks as for the
+"regular" math. However, it was not possible to tweak the visible
+behaviour to mimic 1.2 in all cases, so this might take some time to
+get accustomed to. On the pro side, the new structure allowed
+implementing support for LaTeX's \mbox and \fbox and general
+"switching back to text mode within math", so a lot of "evil red text"
+trickery is not needed anymore.
+
+** Reading old files
+
+LyX now has a new script lyx2lyx which allows to read any old file
+produced by LyX versions as old as 0.12. 0.10 series is in the works
+for 0.10 (1.4 time line) and still older files are in the forge.
+Basically if lyx wrote it lyx will read it. :-)
+
+There is also a strong demand for being able to read files produced by
+_newer_ versions of LyX. While lyx2lyx has an infrastructure in place
+to do such things, the filters to `downgrade' LyX files (from 1.3.0 to
+1.2.x, for example) have not yet been written.
 
 ** Miscellaneous changes
 
 - LyX now automatically uses TeX fonts for screen rendering if they are
   available (it is not necessary anymore to configure your font server).
