After too long a wait, the LyX team are pleased to announce the new stable
release, 1.2.0.

This release has far too many bugfixes and new features to list
comprehensively, but some are listed below.

You can download LyX 1.2.0 here :

Prebuild binaries (mainly rpms for linux distributions) are available

Note that there is no patch, due to the amount of changes.
If you find what you think is a bug in LyX 1.2.0, you may either
e-mail the LyX user's mailing list (, or open
a bug report at

If you're having trouble using the new version of LyX, or have a question,
first check out, and e-mail the LyX user's list if you
can't find an answer there.  
New features

Major improvements have been made to the handling of "insets" such as
footnotes, margin notes, and figure floats. A new minipage facility has been
added to make minipage management easy and powerful. Float parameters can be
set on a per-float basis now. Notes insets can contain arbitrary objects.

A new ERT mode replaces the old LaTeX font and LaTeX environment method of
1.1.6.  This allows the user to fold LaTeX text away just like a float, and
supports both short and long sections of LaTeX commands in an intuitive manner. 

The speed and usability problems with tables that remained in 1.1.6 have almost
all been fixed.  
A powerful new graphics system has been included. This allows the user to set
up converters to allow previews of any input format (for example, LyX can
display inline previews of figures generated from Grace). Many other
improvements to the graphics code has been made.

Support for natbib citations has been added, and more facilities have been
added (such as the ability to search).

The math editor has been mostly rewritten, leading to many new features, such
as :

- possibility to display all standard latex and amsmath symbols (and
  also the \mathcal, \mathbb, and \mathfrak fonts) as long as the
  relevant fonts have been made available to the X server
- support for many amsmath features

- GUI support provided for many more features

- (Better) support for nested macros

Many dialogs and other LyX features have had major usability improvements.  
Other new features include document bookmarks, parsing LaTeX pre-ambles on
LaTeX import, ligature break support, an English thesaurus, and more.  

New document classes dtk, ltugboat, spie and svprobth. 
Bug fixes

A large number of math editor fixes have been made.

A number of obscure drawing errors and crash problems have been fixed, and
several problems with LaTeX output from LyX documents no longer occur.
The problems affecting figure previews, due to ghostscript and xforms,
no longer apply.
A work around for long tab names in dialogs has been included.
Various miscellaneous fixes.
Upgrading from earlier LyX versions

You should have no problems upgrading from LyX versions 1.1.5 and 1.1.6. It is
nevertheless recommended that you keep backups of important documents.  Most
documents will load in 1.2.0 without problems. Older versions of LyX cannot
read documents saved with LyX 1.2.0.

If you are having problems displaying figures in LyX, make sure you have a
recent version of the ImageMagick package installed.  
There are some (rare) problems with older documents, especially concerning
floating figures and the use of minipages. Please read the UPGRADING file for
more information on this.
