This document contains a brief list of the most important OS/2-specific changes
in the Qt library from release to release.


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.
