I am going to remove 2.1 alias, 3.0 branch and related tags from Yii2 repository this month. What’s going to be affected:

• Release 3.0.0-alpha1 · yiisoft/yii2 · GitHub
• yiisoft/yii2 - Packagist
• yiisoft/yii2 - Packagist
• GitHub - yiisoft/yii2 at 3.0

If you use any of these, please prepare. Thanks.
