As i can see there isn't any update on your library for years.
Yes, the signature algorithm has not changed in years and the ECDSA mathematics will not change either.
Signatures are a mathematical algorithm that is always the same. Have you ever received an update for your calculator?
But if you want I can change the version number. :-)
If you want software with many updates, the best thing to do is buy Windows.
A little tip from me: You can recognize good software by the fact that there are few updates and not many!
