according to the following rule,

^1.2.3  is >=1.2.3 <2.0.0    
^0.2.3  is >=0.2.3 <0.3.0   (0.x.x is special)
^0.0.1  is =0.0.1   (0.0.x is special)
^1.2    is >=1.2.0 <2.0.0   (like ^1.2.0)

I am wondering why there is the difference as below between Semver ^12.1.0 and ^12.1.1 in my yarn.lock file? ^12.1.0 is resolved to 12.1.1, meanwhile ^12.1.1 is resolved to 12.3.0 (the latest version).

any help would be appreciated, thanks.
