- Apr 2013 Added private derivation for i >= 0x80000000 (less risk of parent private key leakage)
- Apr 2013 Switched from multiplication by IL to addition of IL (faster, easier implementation)
- May 2013 Added test vectors
- Jan 2014 Rename keys with index ≥ 0x8000000 to hardened keys, and add explicit conversion functions.
