Composer can't find package symfony/polyfill-intl-icu ~1.0

Your requirements could not be resolved to an installable set of packages.

Problem 1
- symfony/symfony 2.8.x-dev requires symfony/polyfill-intl-icu ~1.0 -> no matching package found.

Shouldn't it be 1.0.x-dev ?

We have minimum-stability set to dev in the composer.json files of the polyfill packages. If you already like to use them (or the not released Symfony 2.8) in your project, you will need to decrease the minimum stability in your project's composer.json file or explicitly require unstable dependencies.

Ok I can wait a month until Symfony 2.8 will get stable release, thanks
