  * **linux-x64-glibc-217**: Linux x64, compiled with glibc 2.17 to support [older Linux distros](https://en.wikipedia.org/wiki/Glibc#Version_history), QNAP QTS 4.x and 5.x, and Synology DSM 7, and other environments where a newer glibc is unavailable.
  * **linux-x86**: Linux x86 (32-bit) binaries compiled against libc 2.17, similar to the way the official [linux-x64 binaries are produced](https://github.com/nodejs/node/blob/main/BUILDING.md#official-binary-platforms-and-toolchains). 32-bit Linux binaries were dropped for Node.js 10 and 32-bit support is now considered "Experimental".
  * **linux-armv6l**: Linux ARMv6 binaries, cross-compiled on Ubuntu 16.04 with a [custom GCC 6 toolchain](https://github.com/rvagg/rpi-newer-crosstools) (for Node.js versions earlier than 16) or Ubuntu 18.04 with a [custom GCC 8 toolchain](https://github.com/rvagg/rpi-newer-crosstools) (for Node.js 16 and later) in a similar manner to the official linux-armv7l binaries. Binaries are optimized for `armv6zk` which is suitable for Raspberry Pi devices (1, 1+ and Zero in particular). ARMv6 binaries were dropped from Node.js 12 and ARMv6 support is now considered "Experimental".
- * **riscv64**: Linux riscv64 (RISC-V), cross compiled on Ubuntu 20.04 with the toolchain which the Adoptium project uses (for  now...). Built with --openssl-no-asm (Should be with --with-intl=none but that gets overriden)
+ * **riscv64**: Linux riscv64 (RISC-V), cross compiled on Ubuntu 22.04 with the ubuntu toolchain. Built with --openssl-no-asm (Should be with --with-intl=none but that gets overriden)
  * **loong64**: Linux loong64 (LoongArch64), cross compiled on Ubuntu 20.04 with the toolchain.
 
 "Experimental" status for Node.js is defined as:
