After three months in beta testing, WinRAR 4.00 is fully-baked and ready for consumption. It is now available to download for Windows, Mac OS X and Linux. The biggest improvement over the previous WinRAR versions is the decompression, which is now 30-percent faster depending on the file format used.

Additional features include a password manager for regular compression jobs, although passwords are not encrypted. When extracting multiple archives you are now able to set WinRAR to use the same password for all of them. Something worth knowing is that WinRAR 4.00 does not work on older Windows OS's such as 98, ME and NT. The Minimum requirement for WinRAR 4.00 is now Windows 2000.
