----------------------------
As with the previous major version 1.2.0, many things make this new
-release an exciting one. This should not however hide the fact that
-the `under the hood' changes to the code have been (again) very
-important. One of these invisible changes that have been going on for
-a long time is the so-called GUI-independence project. We are glad to
-announce that version 1.3.0 shows the first results of this.
+release an exciting one. One of the major projects that has been going
+on behind the scenes is the so-called GUI-independence project. We are
+glad to announce that version 1.3.0 shows the first results of this.
+LyX now comes in two flavours: Qt-LyX and xforms-LyX!
+
+Although this is the most visible change in version 1.3, this should not
+hide the fact that the `under the hood' changes to the code have again
+been very important. A detailed list can be found below.
** Qt frontend
This is of course the most visible new feature. This frontend supports
-either Qt 2.x or 3.0.x and is mostly feature complete. The dialogs are
-not copies of those of xforms, but that some different design choices
-have been made.
-
-There are a few caveats though:
+either Qt 2.x or 3.x and is mostly feature complete. Note that some
+of the dialogs are slightly different in design, but are generally
+functionally equivalent.

+Note that if Qt is using Xft2/fontconfig, you may need to install the
+latex-ttf-fonts package on ftp://ftp.lyx.org/ to get maths symbols
+displayed properly.
** Xforms frontend
-The avent of the Qt frontend does not mean that the historical xforms
+The advent of the Qt frontend does not mean that the historical xforms
frontend is dead. Actually, it is still the one which is the best
-implemented, since we had much time to polish it. In this release,
+implemented, because we have had more time to polish it. In this release,
most of the dialogs have been redesigned to be tighter.
Note also that the xforms library has been very recently updated to
-version 1.0. This version has been released under the GPL, and the
-availability of the source means that many bugs that have been
-plaguing LyX have been fixed in xforms. You are advised to upgrade to
-xforms 1.0 to enjoy all these new fixes. As a matter of fact, LyX
-1.3.0 does not support anymore versions of xforms older than 0.89.5.

+In fact, LyX 1.3.0 no longer supports versions of xforms older than 0.89.5.
+
+In most cases the dialogs have been designed to make it impossible to input
+invalid parameters. The exception to this rule is the input of length data.
+Power LaTeX users can still input obtuse "glue lengths", but the widgets are
+highlighted in red if this input is invalid or incomplete. This visual
+feedback makes it easy to see why LyX won't allow you to Apply your changes.
** Gnome frontend
Unfortunately, the development of the Gnome frontend has mostly
-stopped recently and we have therefore disabled it. We strongly invite
-anyone willing to revive this port to volunteer on the developpers
-list.

** Math editor
-Andre??
+There have been a few visible and some not-so-visible changes. On the
+visible side we have better visual feedback regarding the structure of
+a formula, showing the nesting by small purple decorations in the
+formula itself and 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 also is the internal
+structure of font changes which are now proper "insets", just like
+anything else from a square root to an array. This not only simplifies
+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
+support for LaTeX's \mbox and \fbox to be implemented and general
+"switching back to text mode within math", so a lot of "evil red text"
+trickery is not needed anymore. The most visible changes are the following:
+
+- Pressing { and } will insert LaTeX's \{ and \} which show up as { }
+ in the printout. To get LaTeX's {} nesting, you need to type \{.
+
+- Fonts changes now really nest. Repeated application of a font change
+ will result in nested font changes! To remove a font change without
+ removing the "contents", it is now possible to "pull the argument"
+ like in other insets, i.e. put the cursor in the first position of
+ the inset and press 'backspace'.
+
+** Reading old files
+
+LyX now has a new script lyx2lyx which enables the reading of any file
+produced by LyX versions as old as 0.12. Work is in progress on files
+created with LyX 0.10 (LyX 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 to be able to read files produced by
+_newer_ versions of LyX. While lyx2lyx has the 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 font for screen rendering if they are
- available (it is not necessary anymore to configure your font server).
+- LyX now automatically uses TeX fonts for screen rendering of math
+ equations if they are available (it is not necessary anymore to
+ configure your font server).
+
+- The Insert>Short Title allows the addition of an optional text
+ for section headings and captions that is designed to be used in
+ tables of contents.
+
+- The Insert>Float>Floatflt Figure menu item restores the ability
+ to wrap text around an image which was present in 1.1.6 and
+ removed in 1.2.0
+
+- If you configure with --with-pspell (which uses the PSpell library for
+ spellchecking), you will be able to automatically spell-check
+ multi-language documents, assuming you have the right dictionaries
+ installed.
+
+
+What's new in version 1.2.3?
+----------------------------
+
+LyX 1.2.3 is a maintenance release. It mainly fixes a very bad bug
+where configuring LyX as root could lead to deleting the /dev/null
+special device (this does not impact users of prebuilt binaries).
+Also, a bug where LyX would create zombie processes has been fixed.
+
+** Updates
+
+- updated italian User Guide
+
+- updated french localization
