 CHANGES

+
+4.6.3 (19-11-2010)
+
+  Improvements:
+
+  - general: Updated Qt codebase to version 4.6.3 (see the changes-4.6.3 file
+    for details). This version should be binary compatible with the previous
+    version of Qt for OS/2.
+
+  - general: qmake uses .NOTPARALLEL for some targets to support parallel
+    building of complex applications with the -jN GNU make option.
+
+  - corelib: Significantly improve the performance of directory iterators
+    walking through directories with thousands of files on slow file systems
+    with inefficient cache policies [based on patch by rudi].
+
+  - corelib: Don't report non-existent floppy drives in QDir::drives(). This
+    makes letter A: and B: disappear from standard file dialogs in case if the
+    computer doesn't have the floppy controller at all or it is disabled in BIOS
+    [patch by rudi].
+
+  - corelib: Implemented QSysInfo::os2Version(). Fixes the UserAgent string
+    in QWebKit-based browsers.
+
+  - corelib: Fixed: Hang when attempting to stop the file watcher thread after
+    reusing it for more than one directory (e.g. like in the standard file
+    dialog).
+
+  - network: Added OpenSSL support. This enables visiting web sites using the
+    secure HTTPS protocol in Qt based web-browser applications.
+
+  - network: Improved network disk cache performance by reducing the number of
+    stat() calls twice when expiring the cache items [based on patch by rudi].
+
+  - network: More verbose error messages from QLocalServer/QLocalSocket instead
+    of just "Unknown error".
+
+  - network: QNetworkInterface::hardwareAddress() returns a real MAC and
+    netmask() returns a correct value.
+
+  - plugins: Enabled the MySQL and PostgresSQL Qt plugins. Note that these
+    plugins require MySQL and PostgresSQL DLLs to be installed.
+
+  - gui: DIVE: Detection code of the Panorama video driver now detects the
+    driver presence in memory rather than what will be loaded on next reboot.
+    This also solves redraw problems in cases where Panorama is installed
+    together with some other video extension -- the old method could not
+    detect Panorama and would enable DIVE leading to screen corruption.
+
+  - gui: Send PDF data to a CUPS printer on by default if CUPS is version 1.4.4
+    or above (where printing PDF data was fixed).
+
+  - gui: QCommonStyle::standardIconImplementation(): Generate the stanrad small
+    and/or large icon size if it is missing from the stock icon to avoid icon
+    size differences in e.g. file dialogs.
+
+  - webkit: Try to allocate memory blocks in high memory on OS/2 first and fall
+    back to low memory on failure.
+
+  Fixes:
+
+  - general: Fixed: configure.cmd would not work in Object REXX bmode.
+
+  - corelib: Fixed a deadlock during alien thread termination (copy-paste bug)
+    [found by komh].
+
+  - corelib: Fixed: QProcess::startDetached() would fail with a certain set of
+    arguments [patch by rudi].
+
+  - network: Fixed: QLocalServer/QLocalSocket: Make sure the socket path name
+    always starts with "\socket\". This fixes applications that use local
+    sockets for single application instance detection [based on patch by rudi].
+
+  - network: Fixed: Filter out garbage entries returned by ioctl(SIOCGIFCONF) on
+    OS/2 so they don't appear in the QNetworkInteface::allInterfaces() list.
+
+  - network: Fixed: QLocalServer could hang forever in the destructor trying to
+    close the listen socket being watched by a socket notifier. This fixes the
+    Assistant application hang at startup.
+
+  - gui: Fixed: Doing Drag-n-Drop over a Qt target in DIVE mode would corrupt
+    the window contents.
+
+  - gui: Fixed: Children with real HWNDs (a.k.a native widgets) were painted
+    over by the parent widget causing annoying flicker (smplayer).
+
+  - gui: Fixed: In Dive mode, the screen would get corrupted if the application
+    created a child window with a real HWND (as e.g. smplayer does).
+
+  - gui: Fixed: Qt Assistant would corrupt screen at startup in DIVE FB mode
+    [based on patch by rudi].
+
+  - gui: Fixed: DIVE mode was unreasonably disabled in 24-bit color depth
+    display modes.
+
+  - gui: Fixed: Path separator was missing in the output file name when printing
+    to a PDF or PS file in the print dialog.
+
+  - gui: Fixed QFileDialog: Item height in the side bar was increased by
+    increasing icon size which caused ugly icon scaling. Now the item size hint
+    is used instead (based on the normal item height) [vendor bug].
+
+  - gui: Fixed: Possible crash and an endless PM event loop recursion when
+    re-parenting widgets in DIVE mode. This could be seen when dragging a
+    toolbar out of the dock widget, dragging it back then closing the
+    application (crash) or attempting to drag the toolbar out again (endless
+    recursion).
+
+  - gui: Fixed: Assertion shown when dragging the "Computer" item in the side
+    bar of the file dialog.
+
+  - gui: Fixed: QCups would try to unlink() a NULL path which crashed some
+    libc implementations [vendor bug].
+
+  - gui: Workaround: Set O_BINARY for temporary file descriptors we get from
+    CUPS when printing using the PDF engine to avoid file contents corruption.
+
+  - gui: Fixed: Starting the drag operation would take the Qt focus away and
+    close all popups which is unexpected.
+
+  - gui: Fixed: Repainting the widget during Drag-n-Drop outside the
+    drag*Event() callbacks would cause screen corruption under the mouse pointer
+    in DIVE mode.
+
+  - gui: Fixed: Pressing Shift[+Ctrl]]+<numpad_digit> generated digits in
+    NumLock ON mode instead of cursor movement events (which is necessary to
+    make it possible to select text using numpad keys with Shift pressed.
+
+  - gui: Fixed: Hiding the main application window programmatically with
+    QWidget::hide() and then showing it again with QWidget::show() would not
+    activate it from the Qt point of view which prevented the child widgets from
+    getting the keyboard focus (and input).
+
+  - gui: Fixed a crash that could happen at program termination in DIVE mode if
+    a top-level window had a native HWND window embedded in it.
+
+  - gui: Fixed SIGSEGV on SSE2 processors due to misaligned m128i variables
+    on stack (an OS/2-specific GCC 4.x compiler bug).
+
+  - webkit: Fixed: Symbols typed with AltGr as a shift modifier could not be
+    entered in line entry fields in WebKit-based applications.
+
+  - webkit: Fixed: posix_memalign() broken in kLIBC 0.6.3/4 whould crash in
+    QWebKit under heavy memory consumption conditions.
