Public release of LyX version 1.5.0 (beta 1)
We are glad to announce the release of LyX 1.5.0 (beta 1).
It is the culmination of 1 year of hard work, and we sincerely hope
you will enjoy the results. The changes are too numerous to
summarize in a few words, with initial unicode support as the flagship
of new features. Jump directly to the end of this message if you want
to know the differences to the latest stable version (1.4.4).
As usual with major releases, a lot of work that is not directly
visible has taken place. The core of LyX has seen more cleanups and
some of the new features are the direct results of this work.
See the file RELEASE-NOTES for some known problems in that release.
In case you are wondering what LyX is, here is what
http://www.lyx.org/ has to say on the subject:
LyX is a document processor that encourages an approach to writing
based on the structure of your documents, not their appearance. It
is released under a Free Software / Open Source license.
LyX is for people that write and want their writing to look great,
right out of the box. No more endless tinkering with formatting
details, 'finger painting' font attributes or futzing around with page
boundaries. You just write. In the background, Prof. Knuth's legendary
TeX typesetting engine makes you look good.
On screen, LyX looks like any word processor; its printed output -- or
richly cross-referenced PDF, just as readily produced -- looks like
nothing else. Gone are the days of industrially bland .docs, all
looking similarly not-quite-right, yet coming out unpredictably
different on different printer drivers. Gone are the crashes 'eating'
your dissertation the evening before going to press.
LyX is stable and fully featured. It is a multi-platform, fully
internationalized application running natively on Unix/Linux and the
Macintosh and modern Windows platforms.
You can download LyX 1.5.0beta1 here (the .bz2 are compressed with
bzip2, which yields smaller files):
Note that due to the ammount of changes no patch is provided to upgrade
from version 1.4.4.
Prebuilt binaries (rpms for linux distributions, Mac OS X and Windows
installers) should soon be available at
If you find what you think is a bug in LyX 1.5.0beta1, you may either
e-mail the LyX developers' mailing list (lyx-devel @ lists.lyx.org), or open
a bug report at http://bugzilla.lyx.org
If you're having trouble using the new version of LyX, or have a question,
first check out http://www.lyx.org/help/. If you can't find the answer there,
e-mail the LyX users' list (lyx-users @ lists.lyx.org).
The LyX team.
What's new in version 1.5.0 (beta 1)?
LyX 1.5's big goal was to use unicode internally and so resolve a slew
of existing problems with special characters and non-alphabetic
languages. LyX 1.5 is able to output unicode (in addition to
encodings current available), so that you can use LaTeX's new utf8
encoding or such brand new typesetting systems as XeTeX.
Since the change to unicode touched much of the code base and some
areas still need a cleanup it is very likely that some bugs related to
the unicode transition still exist. Please have a look at the Known
bugs in LyX 1.5 page if you encounter a bug that seems to be related
to unicode. If it's not there, then please report it to the lyx-devel
* Multiple views of the same buffer
LyX can now display multiple views of the same buffer. I.e., you can
now open a single document in multiple windows and work on different
parts of it synchronously.
LyX has another long-awaited feature: a basic outliner mode, in which
you can move chapters and sections around in the Table of Contents
dialog. (The outliner has been backported and was released with LyX
* Session managment
LyX is now able to remember window size and position and it will
reopen the documents you worked on last time around. If you've
selected the feature in the Preferences dialog, it'll even move the
cursor to the place you were working on last! Furthermore, toolbars
can (finally!) be switched on/off in View->Toolbars and moved about in
the LyX window. The session managment will remember their state.
* Source code Viewer
As a kind of "anti-preview-latex", a dialog was implemented that lets
you view the source code of a given paragraph/selection or the whole
* New Font Selection Interface
LyX's font selection abilities have been one of its weakest and most
outdated components. A completely new interface was implemented that
provides access to the power of LaTeX's font selection scheme.
* Tabular extensions
LyX's table support is certainly less powerful than that of
LaTeX. support for the booktabs package was implemented, which
provides beautiful and elegant tabulars.
Native LyX support for the nomencl package was implemented. With this,
you can treat your document with all sorts of nomenclatures,
glossaries and fancy notations.
* Tabbed Widget
LyX now uses tabbed widgets to display multiple documents.
* Frontend News
LyX 1.5 will use the Qt4 toolkit. This is especially good news for
Windows users, since there's an official, GPL version of Qt4. They no
longer have to rely on an unofficial port of the Unix Qt3 library to
Windows. The good old XForms frontend went the way of the dodo. It
was both hated and loved, and certainly shaped the unique look of LyX
in the past. It was finally killed off, however, by the switch to
unicode. The Qt3 frontend was removed. The work on the GTK frontend
has been transfered to a branch because its development has
* Change tracking enhancements
Major parts of the change tracking code were rewrote addressing
several problems that existed in the existing implementation.
* Converter file cache
A cache for converted files, such as included figures, was
implemented. This can speed up LyX's performance considerably when
displaying documents with many included figures that need conversion
to a format that can be rendered on screen. The converter file cache
is disabled by default, and there is no GUI for configuring it yet. If
you want to use it, add the line
to your preferences file. The default maximum age of a cached file is
6 months. You can change that with the line
where xxx is the maximum age in seconds.
* Unified Windows installer
The two windows installers are being merged and bug reports regarding
both installers are welcome.
* Under the hood
As usual, one big task has been the ongoing code cleanup of the LyX
core. Performing this cleanup makes the code more understandable and
easier to maintain. It also leads inevitably to a more robust
application. Nonetheless, it's an unfortunate fact of life that ugly
code is sometimes faster than pretty code. We're well aware that LyX
1.4 is slower than LyX 1.3. One important goal of this 1.5 development
series has been to bring this speed back.
** Bug fixes
Lots of long-lasting bugs have been fixed, as documented in LyX
