Just a few months after the release of MediaPortal 1.3, the MP team forges ahead by providing the MediaPortal 1.4 Pre-release version.
On this new version, developers have focused their efforts on optimization, but also on the elimination of bugs, like the problem of image resizing when connecting a PC to a TV or an amplifier via HDMI. From the optimizations size, a faster software boot is noted, support for WASAPI (finally!), the improvement of Blu-ray reading even if the Java is still not supported, or the Audio Renderer optimization. The complete list of new features is available here.
Finally, note that the developers have specified that MP 1.4 would be the last version to support Windows XP.
