Version 0.8 added support for jailbreaking the iPhone 3GS.

Version 0.9b3 was released for Windows and Mac OS X, and it allows iOS 3.0 through 3.1.2 to be jailbroken. It includes support for all devices except the iPod touch (3rd generation), and supports a tethered jailbreak on iPhone 3GS units and iPod touch (2nd generation) units with new bootroms. In addition, this version supports custom boot and recovery mode logos, as well as verbose mode on bootup.

Version 0.9.2 supports jailbreaking of all iDevices (at the time) with iOS 3.0 through 3.1.2 on Windows and Mac OS X, as well as 3.1.3 on S5L8900 devices. Version 0.9.3 adds support of internet tethering IPCC hack on those devices and 0.9.4 allows jailbreaking of early iPod touch (2nd generation) with iOS 3.1.3.

Version 0.9.5b5-5 supports jailbreaking the iPhone 3G and iPod touch (2nd generation) (old bootrom) with iOS 4.0 on Windows and Mac OS X.

Version 0.9.10b1 adds support for iOS 4.2.6 through 5.0.1 (though iOS 4.2.9, 4.2.10, 4.3.4, 4.3.5, and 5.0 are tethered on devices invulnerable to the 0x24000 Segment Overflow). This build of redsn0w is not capable of jailbreaking S5L8940 or newer devices.
