What´s New in version 4.0.2:
High-dpi screen support has been added on MacOsX Lion for the pdf viewer, the symbols and the toolbars icons (because of a Qt 5 limitation, icons are still pixelized in the 'push buttons' and in the menus for the moment)
structure tags (chapter, section, ...) are now totally boldified in the editor
the 'regular expression' option is no more checked by default in the 'replace' widget.
on linux, session file is no more stored in the temp/ directory (some linux distribution reset this directory at each reboot), but in the 'home/.cache' directory.
detection of acrobat reader 11 and ghostscript 9.07 has been added (for new users)
windows versions are now compiled with Qt 5.0.2 (the Qt bug about the save file dialog has been fixed in this Qt release)
ar and lv translations has been added (thanks to Koutheir ATTOUCHI and Sandris LACIS)
