Pretty sure this won't pass with PHP 7.1

[davidbyoung]

@meinemitternacht If I understand Composer version constraints correctly, ^7.0 means >=7.0.0,<8.0.0. I'm not sure @TomasVotruba's change will prevent Opulence from working with PHP 7.1. Or, have I missed something?

[meinemitternacht]

Disregard, I should not have assumed similarity between their syntax and Regex.

[TomasVotruba]

@opulencephp That is exactly right. ^7.0 allow all 7.x versions, but not above.
Thus, 7.1 will work.

@TomasVotruba

~7.0 and ^7.0 are equals right?

By official documentation.

~1.2 is equivalent to >=1.2 <2.0.0
^1.2.3 is equivalent to >=1.2.3 <2.0.0

Am I right?

PS: I have always thought that caret (^) has the main purpose for for 3 digits, I mean patch version.
Like for example ^7.0.8. It means I want to obtain higher then 7.0.8 and lower then 8.0.0.

Thanks for explanation.

They are not equal: http://stackoverflow.com/questions/22343224/difference-between-tilde-and-caret-in-package-json

@f3l1x For php version check they are the same.
