i got horse breeding going on at my base, can there be a shop for selling horse and can my base be used as a warp point for that shop?

i know, i did that, it just weird how version 1.11 was not revealed on the minecraft screen after you start it up and before you press the play button

looking at my server list on minecraft and i am seeing Waterfall 1.8.x, 1.9.x, and 1.10. every time i try to get in, it said the server is outdated
