I am thinking before 1.19.1 when chat reporting was added. 1.7 to 1.12 seem to have less requirements to run for lower end pcs. Its just some chill fun and not pvp focused so being newer than 1.9 shouldn't matter. I am thinking 1.15 maybe since it added bees. I guess its a compromise between how well the game runs on lower hardware and what features we want.
