+          * 🤖This modern version of i686-elf-tools has automatically been built by GitHub Actions
+          * ⚠️It is completely untested, and merely provided for your convenience in the event that you would prefer to use a modern version of the toolchain
+          * 🚀Having said all this, the [original release](https://github.com/lordmilko/i686-elf-tools/releases/tag/7.1.0) of the toolchain has been thoroughly tested, and is generally recommended unless you specifically know that you need to use a newer version
