+# To update the Clang compiler:
+# - Change the versions below, and the MSYS2 version in libcxx.mk
+# - Run the script ./contrib/devtools/update-clang-hashes.sh
+# - Manually fix the versions for packages that don't exist (the LLVM project
+#   doesn't uniformly cut binaries across releases).
+# The Clang compiler should use the same LLVM version as the Rust compiler.
