[semver] semver.mwl.be doesn't interpret the caret (^) operator same way as composer

[phansys]

Current documentation about Caret Version Range states that ^1.2.3 is equivalent to >=1.2.3 <2.0.0, but semver.mwl.be interprets ^1.2.3 as >=1.2.3 <1.3.0, and ^1.2 as >=1.2.0 <1.3.0.

See these examples:

semver.mwl.be is not maintained by the composer team. Report this to their maintainers.

your bug report is wrong. You are reporting about ^1.2.3, but your tests are using ^0.1.1.

The tool is perfectly right in this case. A 0.x major version behaves in a special way in semver, as it means that any increment of the next number can be a BC breaking release too (and so ^ rejects them).

See https://semver.mwl.be/#?package=symfony%2Fsymfony&version=%5E3.2.1&minimum-stability=stable for the proof.

@alcohol this issue should be closed, as there is no issue at all

and here is a quote from the composer doc (the last sentence in the paragraph you referenced in the original issue):

For pre-1.0 versions it also acts with safety in mind and treats ^0.3 as >=0.3.0 <0.4.0.

Sorry for the misunderstanding, I didn't noticed the special behavior for pre-1.0 versions. Thank you.
