New release to fix PHP7 requirements

[davidromani]

Hi.

It is possible to release a new minor version to fix PHP7 requirements? I'm using this bundle in my project, only with stable versions, and I can't upgrade.

I want to keep my composer.json requirement without introducing a dev branch.

    "require": {
        "ali/datatable": "^2.1",
...

Thx.

@AliHichem, could you create a minor version release for the latest version?
