Redsn0w for latest iOS Versions
If anyone wants jailbreak earlier versions such as iOS 10 ,iOS 9, iOS 8 or iOS 7, it should bypass the Redsn0w jailbreak. Because, it is not available Redsn0w versions for these jailbreaks.
It should try Goblin Jailbreak for iOS 10.3.3 to iOS 10.3 versions and Meridian,C0F3  and H3lix Jailbreak  for iOS 10.3.3 to iOS 10. Also, Houdini semi jailbreak can be used as another jailbreak alternative. Saigon jailbreak for iOS 10.2.1, Yalu jailbreak for iOS 10-10.2, Pheonix jailbreak for iOS 9.3.5,  Pangu jailbreak for iOS 9.2 - iOS 9.3.3,PP Jailbreak for iOS 9.2 -iOS 9.3.3/ iOS 8 - iOS 8.4, TaiG Jailbreak for iOS 8.0 - iOS 8.4 tools, those who wants latest Cydia supports.
LiberiOS jailbreak,To. Panga Jailbreak,C0F3 and Electra Jailbreak are the newly released jailbreak tools for iOS 11 & higher versions up to iOS 11.1.2. Houdini semi jailbreak compatibility also increased to iOS 11 to iOS 11.1.2 versions.  Also Panadora Jailbreak for iOS 11.2/iOS 11.2.1 jailbreak. Further, Keen team proved the possibility of iOS 11.1.1 jailbreak at PoC 2017 recently and previously iOS 11 Jailbreak at MOSEC 2017.
Even Redsn0w not compatible with all the latest devices as following.
iPhones
iPhone 7 & 7 Plus, iPhone 6S & 6S Plus, iPhone 6 & 6 Plus, iPhone 5S, 5C & 5

iPod Touches
iPod Touch 6G & 5G
But we can not reject this tool entirely. It will have some of the 32-bit devices supports of Redsn0w. Lots of latest and leading jailbreak team developers have rejected older device support.
According to all these reasons, we cannot entirely reject Redsn0w tool’s renewing. However, it has doubt having Redsn0w tool for neither 64-bit nor 32-bit devices too. Not having tool version of this possibility is 99%.
However new jailbreak tool called as Phoenix jailbreak released for iOS 9.3.5 running 32-bit devices recently.

Specialty of Redsn0w

It worked for both Windows and Mac surfaces, when compared with same era releases just like Sn0wbreeze & other tools.
Before start the jailbreak process, it never asks getting back up of your device. Cause, it did not erase current data on your device while running the jb process.

Just Boot - Help to reboot the device.
Pwned DFU - To put the device into DFU mode.
Recovery Fix - To fix recovery mode loop error.
SHSH blobs - To downgrade iOS version, when Apple disable doing it.
Select IPSW - While processing jailbreak, it will detect the IPSW automatically. No need to do it manually.
Custom IPSW - When it needs to unlock iDevices, this will really help to create custom firmware upgrade.
Even More - It has Restore, Identify, Backup, Tickets, DFU IPSW and Preferences options under the Even More.
Under the Preferences option it has ECIDs, Boot Args, Boot logos.
