1 Qt 4.3.2 is a bug-fix release. It maintains both forward and backward
2 compatibility (source and binary) with Qt 4.3.0 and Qt 4.3.1.
4 The Qt version 4.3 series is binary compatible with the 4.2.x, 4.1.x and
5 4.0.x series. Applications compiled for Qt 4.0, 4.1 or 4.2 will continue to
6 run with Qt 4.3.

318 However all display columns were always aliased - even when not
319 necessary. From now on, display column names will only be aliased when
320 there are name clashes, and only the conflicting columns will be

372 clickable.
373 * [174276] Fixed resizing performance in cases where wrapping is
374 disabled.

376 be lost when the text was copied and pasted.
378 - QTextLayout
379 * Fixed a regression in the line breaking algorithm that lead to wrong
380 results for justified text.
382 - QTextStream
383 * [174516] (Windows) Fixed a bug in readLine() when reading "\r\r\n"
384 from devices opened in QIODevice::Text mode.
386 - QToolBar
387 * [270967] Fixed the behavior of floating toolbars.
