The ReactOS project has released version 0.3.5 of their ambitious operating system. ReactOS aims to be a “ground-up implementation of a Microsoft Windows XP compatible operating system. ReactOS aims to achieve complete binary compatibility with both applications and device drivers meant for NT and XP operating systems, by using a similar architecture and providing a complete and equivalent public interface.” This new version comes packed with improvements.
The most important changes are summed up as follows:
- Updated bootloader (FreeLdr), with some parts rewritten for better compatibility and better code maintenance
- Memory (heap and pools) corruptions fixes throughout the whole system
- Kernel: a number of critical bugs fixed over the whole kernel, and rewrite of an early initialization part of the Memory Manager
- Win32 subsystem: overall improvements in the subsystem, involving both user and kernel mode components
- Base CRT library had key parts reworked in favor of better compatibility
- Command shell (cmd.exe) improvements, especially in interpreting batch scripts
- Font changes for better metrics compatibility
- Internationalization support improvements with a keyboard layout switcher, working Regional Settings Control Panel Applet, 1st stage setup localization into quite a few languages, and more keyboard layouts added
- Almost all kernel mode drivers and user mode applications, control panel applets, DLLs were worked on, resulting in improvements, bugfixes and more functionality
