++ The ParseIP and ParseCIDR ++ functions now reject IPv4 addresses which contain decimal components with leading zeros. ++ These components were always interpreted as decimal, but some operating systems treat them as octal. ++ This mismatch could hypothetically lead to security issues if a Go application was used to validate IP addresses ++ which were then used in their original form with non-Go applications which interpreted components as octal. Generally, ++ it is advisable to always re-encoded values after validation, which avoids this class of parser misalignment issues. ++
