更新日志

版本	说明
8.5.0	Now throws a ValueError when the hostname length is equal to or greater than 128 bytes, when the port is negative or greater than 65535, or when the timeout or retries values are lower than -1 or too large.
8.1.0	The `auth_protocol` now accepts `"SHA256"` and `"SHA512"` when supported by libnetsnmp.
