There's still a few months left before KDE Software Compilation 4.5 will be released, but for the interim there are the usual monthly point releases of the current stable branch. As such, with the start of a new month, KDE Software Compilation 4.4.3 was released this morning.
KDE SC 4.4.3 improvements, according to the release announcement
, are many fixes in Konsole, enhanced Flash plug-in support for KHTML to work with the newest YouTube skins, case-sensitivity in renaming fixes in KIO (KDE's network-transparent I/O library), and hiding the mouse cursor in certain scenarios has been fixed.
