How does this relate to https://github.com/lettuce-io/lettuce-core ?

[kutzi]

It's kind of obvious that https://github.com/lettuce-io/lettuce-core superceded this repository. However it's not immediately clear on the 1st look if it's so - we can even see rather new issue report in this repo.

Maybe you want to add a prominent disclaimer pointing to the new repo and put this repo into something like maintenance mode if possible?
