PHP compatibility version

[kabeocho]

This package is setted as PHP 5.3+.

One of it's dependencies Doctrine ~2.3, installs Doctrine 2.5 that is 5.4+

I suggest to change the Doctrine version to 2.4.* to remain 5.3+ compatible.

Or raise the php version required and tag it, why should this stay compatible with a EOL php version

I agree that new versions can be 5.4+ compatible, but the problem is that none of the available tags are 5.3+ compatible.
