Hello 👋

I am trying to use the zig nightly build, and I want to use zls with it, but I can't figure out how to get a zls version that's supposed to work with it.

I tried just building zls myself using the nightly zig compiler, but seems like it's currently broken. I get:

zls$ zig build -Doptimize=ReleaseSafe
[... snip ...]
pub const Pool = @compileError("deprecated; consider using 'std.Io.Group' with 'std.Io.Threaded'");

Is there a zls commit that can be used with the latest zig nightly build (zig-x86_64-linux-0.16.0-dev.1657+985a3565c), or simply not at the moment?

thanks
