The release info for example at https://github.com/bazel-contrib/toolchains_llvm/releases/tag/v1.6.0 gives an example use of llvm version 16.0.0:

bazel_dep(name = "toolchains_llvm", version = "1.6.0")

# Configure and register the toolchain.
llvm = use_extension("@toolchains_llvm//toolchain/extensions:llvm.bzl", "llvm")
llvm.toolchain(
   llvm_version = "16.0.0",
)

use_repo(llvm, "llvm_toolchain")
# use_repo(llvm, "llvm_toolchain_llvm") # if you depend on specific tools in scripts

register_toolchains("@llvm_toolchain//:all")

However, if I try it on my machine, the build process fails as follows:

[7 / 10] [Prepa] Expanding template external/toolchains_llvm++llvm+llvm_toolchain/module-x86_64-linux.modu

Now, I know that this is easily solved. But perhaps, move past the v 16.0.0 to avoid this one more papercut to have a more out-of-the-box experience?
