Raw Blame History

Qt 4.3.1 is a bug-fix release. It maintains both forward and backward
compatibility (source and binary) with Qt 4.3.0.
The Qt version 4.3 series is binary compatible with the 4.2.x, 4.1.x and
4.0.x series. Applications compiled for Qt 4.0, 4.1 or 4.2 will continue to
run with Qt 4.3.

General Improvements
--------------------
- Translations
* Updated the German translation to provide complete coverage of Qt.
- QDBusView
* Added icons for Mac OS X and Windows.
- Intel C++ Compiler for Linux
* Added support for version 10 of the compiler. See the Compiler
Notes documentation for known problems and work-arounds for this
compiler.
* Added linux-icc-32 mkspec, for building with the 32-bit compiler
on 64-bit hosts.
Third party components
----------------------
- FreeType
* Security fix (CVE-2007-2754): Integer overflow in the
TT_Load_Simple_Glyph function in freetype 2.3.4 and earlier allows
remote authenticated users to execute arbitrary code via crafted BDF
fonts.
- SQLite
* File descriptors are not inherited during spawn() anymore.
Build System
------------
* Fixed native builds on ARM architectures.
