Earlier this month we reported on the Lightspark Flash Player continuing to advance, while today version 0.4.2 has been officially released. Lightspark is written entirely from open Adobe Flash/SWF documentation and hooks into Gnash, another free software Flash player in certain areas for now.

The main features of the Lightspark 0.4.2 release are using fontconfig for font selection, greater compatibility with YouTube videos, sound synchronization support, Google Chrome/Chromium plug-in support, and Mozilla Firefox Out-Of-Process Plug-In support.

The release announcement and download links for Lightspark 0.4.2 can be found in the developer's blog post. Packages are already available for Ubuntu and Fedora users.
