ReactOS 0.4.2 has been released, as part of the project's new, faster release cycle. Beyond the usual updates to external dependencies such as Wine and UniATA, much work has gone into refining the experience of using ReactOS, especially with respect to the graphical shell and the file explorer. Perhaps the most user visible change however is the ability now to read from and write to several Unix filesystems, namely ext family, ReiserFS, and UFS. Native built-in support for these filesystems should make for considerably easier interoperability than the current out-of-box experience provided by Windows, and there is more to come in the future.
