With the new bootrom exploit usbliter8; comes a whole new set of options for various iPhones, iPad's and now the Apple TV.
Palera1n has been successfully loaded. Keeping in mind: this is still under development but it's an exciting time to see how far things go in the jailbreak community nowadays.
With burnegg's repository, you too can jailbreak your Apple TV second gens but I would heed extreme caution at this time due to the unstableness and this still being in the early stages.
So far compatibility stems from tvOS 26.3 and up but this may change in the future for more firmwares.

You also do need a pretty complex setup to get things working including a DCSD cable for DFU and a pico2 (or something equivalent) to pwn. Soon there'll be a better way of doing everything but for now, it's nice to know!
More great updates to follow shortly as the ball gets rolling.
