Eaglercraft 121 10
In a move that surprised few legal experts but devastated the player base, Mojang AB issued against the primary repositories.
However, there is an important distinction. The “1.21” label is aspirational rather than literal. The underlying client is actually still , modified with plugins and server‑side patches to emulate newer content. This is why the GitHub README contains two separate headings: one for “Eaglercraft 1.21 javascript runtime” and another that still says “Eaglercraft 1.8.8 javascript runtime.” The developer is transparent about this: the client itself is based on the stable 1.8.8 core, but the multiplayer server can simulate blocks, items, and mobs from later updates. eaglercraft 121 10
