Texmaker

Texmaker is a Qt4/Qt5 LaTeX editor. Texmaker runs natively on Unix, macosx and win32 systems.
Texmaker includes unicode support, spell checking, auto-completion, code folding and a built-in pdf viewer with synctex support and continuous view mode.

Version 4.0.2 :
Mac OS X High-dpi support has been added to the pdf viewer, the symbols and almost all of the icons. The part/chapter/section... tags are now totally boldified in the editor for a better detection. On linux, the session file is now stored in the standard ./cache directory instead of the /tmp folder. New translations have been also added.

Version 4.0.1 :
A potential risk of crash when synctex is sending a bad page number has been fixed.
The -Pdownload35 option has been added to the default dvips command for MiKTeX users on windows.

Version 4.0 :
The code has been ported to Qt5 (but this version can also be compiled with Qt4).
From this version, Texmaker will be principally developed under QT5.
A keyboard shortcut has been added to toggle between the master and the current document.
A specific "quick build" command has been added for the .asy files : the asymptote figures can now be compiled and displayed with the F1 shortcut.

Version 3.5.2 :
The bug about the shortcut of the "quick build" command has been fixed.

Version 3.5.1 :
A wizard to export the current document to html or odt format has been added. The system PATH can now be completed in the configuration dialog and a "quick build" mode for XeLaTeX has been added. Some bugs about the keyboard shortcuts have been fixed.


Version 3.5 :
The internal pdf viewer has been widely improved. Users can now rotate pages, choose to display one (in continuous or non-continuous mode) or two pages at the same time. A presentation mode has also been added.
Capturing text is now supported for the regular expressions and a new option has been added to the command line which allows the insertion of a piece of code in the current document.


Version 3.4.1 :
A bug about the buttons in the configuration dialog has been fixed.
While using Texmaker on the gnome desktop, the icons for the standard actions are now issued from the gtk theme.


Version 3.4 :
With a new option, the "--output-directory=build" parameter is added automatically to the (pdf)latex command and the log and pdf files are reached by Texmaker in the "build" subdirectory . The commands "Open a terminal" and "Save a copy" have been added and regular expression can now be used in the find/replace dialogs. A words counter has also been added to the internal pdf viewer and the biblatex entries have been completed with the optional fields. Some minors bugs have been fixed and the MacOsX Lion full-screen mode is now supported.
