It would seem that neovim 0.10.* is causing a few issues with zk-nvim currently.
So, this release is the final release to support neovim 0.9.5.
This will help with bug triaging and will still give people on neovim 0.9.5 a solid amount of time to upgrade to 0.10 without missing out on any major features / changes to zk-nvim in the meantime (as features / changes don't happen so often here).
Hopefully the new ZkGrep feature will come to fruition soon too.
It will help that this feature gets built fresh for 0.10.* as there's still a few creases to iron out.
