Can anyone explain me why composer is selecting the wrong version for pre-1.0 version selector ?

[Matteo Orefice]

Hi

We have two composer packages name A and B

• We develop a package B on which depends a package A
  
• the package B has a dev-master and a v0.1.0 release tag
• the package A requires B at version ^0.1@dev : composer require B:^0.1@dev
• composer install selects the v0.1.0 instead of dev-master

I cannot understand why ...

But if I composer require B:^0@dev omitting the .1 dev-master is selected....

Thanks
