Compatibility with Symfony 3.0

[mkrauser]

currently omnipay requires

"symfony/http-foundation": "~2.1"

which makes it currently unusable in Symfony 3.0 projects.
Symfony 3.0 was released yesterday.

Thank you for looking into this.

Also, guzzle 3.9, which is also required by omnipay-common required the symfony event-dispatcher 2.x which results in the same problem

And I would recommend to change the current dependency into "symfony/http-foundation": "~2.7.0". With http foundation 2.8.0 you receive symfony/polyfill-php54 for free and as PHP 5.6 user I do not like to see such a dependency entering my project suite.

Hi Barry,
Could you please tell me the overall state of OmniPay version 3.
I see that you've been replacing Guzzle with PHP-HTTP.
Is there a reason you chose not to use Guzzle 6?
What is left to be done in omnipay-common?
What's the difference between branch 3.0 and 3.0-simple? Do they have different purposes? I see one uses Guzzle, and the other one does not.
I see you require PHP 5.6, or 7: "php": "^5.6|^7". I use php 5.5.29, would it be ok with 5.5?
Thanks,

Php 5.5 is not supported anymore.
Guzzle will be de default adapter for Php http, just not tied to it.
Overall state is that this should be able to release not to far from now, while 3.0 branch can be pushed back as 4.0

3.0 is simpler. Both use psr7 and both can support guzzle.

[barryvdh]

Sorry, 3.0-simple is simpler. It's an intermediate version for easier upgrading.

Barry,
Will version 3 continue with Guzzle or PHP-HTTP?
Thanks
