Hello,

thank you for creating this pull request. However did not open it on the "master"
branch. Our Git workflow requires all pull requests to go through "master" branch
and the release masters then merge them back into stable branches, if they are
bug fixes.

Please open the pull request again for the "master" branch and close
this one.

Nevertheless I have opened a Jira ticket for this Pull Request to track this
issue:

http://www.doctrine-project.org/jira/browse/DDC-3978

We use Jira to track the state of pull requests and the versions they got
included in.

@nicolas-grekas should travis also to be changed for testing with 3.0 components?

[nicolas-grekas]

Not sure it's worth it, symfony/console didn't change that much in 3.0, and since 2.8 is tested, any change should already be reported with deprecation notices. Here, tests tell us than none applies, thus it will work in 3.0.

I thought I had merged this last week! =(

[nicolas-grekas]

you merged it on master, this 2.5 now :) thanks!

@guilhermeblanco can this please be included in a new 2.5 release, so we can finish 3.0 support for the DoctrineBundle? (doctrine/DoctrineBundle#486)

Can probably do a release over the weekend

@Ocramius you meant the last weekend, right? :-P would be great if you can find a moment to release a 2.5 so we can move on with DoctrineBundle.
