Qt 3.3.6 is a bug-fix release. It maintains both forward and backward

Qt 3.3.2, Qt 3.3.1 and Qt 3.3.0.

****************************************************************************

Platforms
---------

- It is now possible to build Qt 3.3.6 on Intel Macs. A universal
  Qt build however requires manual work by 'lipo'-ing a PPC Qt
  and an Intel Qt together.

- Add support for Windows Vista.

Compilers
---------

- The build key when building Qt with GCC 4.x has changed. This means
  you will have to either recompile your plugins or change the
  configure script to not reduce the GCC version string to '4'.

Linguist
--------

Handle input of TAB in the translation textedit.
Import whitespace characters between a <source> and a <byte> child
element properly.

Translations
------------

Various Qt translations contributed by Novell.
