- Configuration/Compilation
* Fixed OpenBSD and NetBSD build issues.
- Legal

* Added an Accessibility overview document.

- Translations
- Added support for the CP949 Korean Codec.
- [138140] The whole Qt source compiles with the QT_NO_CAST_FROM_ASCII
and QT_NO_CAST_TO_ASCII defines and therefore is more robust when
using codecs.
- Added support for HP-UX 11i (Itanium) with the aCC compiler
- Changed dialogs to respond much better to the LanguageChange event.
(i.e. run time translation now works much better.)
- Signals and slots
* [61295] Added Qt::BlockingQueuedConnection connection type, which
waits for all slots to be called before continuing.
* [128646] Ignore optional keywords specified in SIGNAL() and SLOT()
signatures (struct, class, and enum).

This is a bug-fix release. It maintains both forward and backward
compatibility (source and binary) with Qt 4.2.0.
- Configuration/Compilation
* Fixed architecture detection on UltraSPARC-T1 systems.
* Fixed compilation on embedded architectures when qreal is not double.
- Documentation
* Completed documentation for "Implementing Atomic Operations",
which is useful for people porting Qt to a new hardware architecture.

Correia.
- Qt Linguist
