All version info has been gathered from the official changelog, gigaleaks, and online dumps. Updaters in green have been released, while updaters in red remain undumped.
Note 01-U02 in SDK release info mentions adding a SystemUpdater to update SNAKE units for 0.22.1 (SDK 9.6.0). I am assuming this is the first release of any SNAKE SystemUpdater, so I will not be expanding the table below that version until new information pops up.
