What is the most recent version of RedSn0w?

The most recent official version of RedSn0w is version 0.9.15b3. This release was provided by the iPhone Dev-Team to support iOS 6 and added features such as the ability to restore A4 and earlier devices to older firmware versions using saved SHSH blobs. While RedSn0w is no longer updated for modern versions of iOS, it remains a vital tool for the legacy jailbreak community and owners of older hardware like the iPhone 3GS, iPhone 4, and older iPod touch models.
