Qt 5.0 Status
Status as at 2010-06-22
"Qt 5.0 Release Task":https://bugreports.qt.io/browse/QTBUG-25381
Linux - In Testing, mostly works
Mac - In Testing, mostly works
* Fonts rendered incorrectly, see https://bugreports.qt.io/browse/QTBUG-25555
Windows - Untested by me.
Todo:
* Complete removal of QAbstractPageSetupWidget
* Still time for removal of QAbstractPrintDialog?
* Clean-ups and bug fixes in Linux print dialog
* Write a feature matrix for print support on different platforms
* Rewrite tst_qprinter to correctly test platform options per feature matrix, currently very broken
* Write manual printing test plan for features that cannot be auto tested
* Develop auto tests that add/delete printers to test QPrinterInfo
* Review platform specific code still in core
Release criteria
The following criteria must be met on all 3 platforms for release:
- No blocker bugs open
- All unit tests not failing, i.e. passing or skipped for valid reasons
- Platform Plugin fully implemented for all required features
- Print to printer tested visually, no font or layout issues
- Print to PDF tested visually, no font or layout issues
- Print dialog tested, all options function as expected
The following tasks also performed:
* API reviewed for any last clean-ups
* Build system reviewed
* Includes reviewed
* Documentation reviewed
For testing painted output, use the example/richtext/textedit or Qt Assistant.

Mac OSX Differences
The Mac paint engine, print engine and print support plugin actually live in the Cocoa Platform Plugin in qtbase/src/plugins/platform/cocoa due to dependencies between the code. It is hoped to clean these up in a future release.
