ReactOS 0.4.12 is here more than six months after version 0.4.11 to introduce window snapping, a feature that lets users snap windows to be aligned to sides, along with the necessary keyboard shortcuts, more robust and correct font rendering for buttons in various apps, two new themes, namely Lunar and Mizu, and support for Intel e1000 NIC. Under the hood of ReactOS 0.4.12, there are several kernel improvements to make the file system drivers and device power management more reliable, improve the CDFS driver, and fix support for PXE booting. The write-protection functionality has also been rewritten and beefed up with execution protection for better overall security of the operating system.
