Yii2 released a quick patch for the ViewAction class. You can read the release here.
I had problems when I tried to run composer update and apparently they are aware of an issue on the composer side. So if you are following along with the book and already have installed the framework, I don’t recommend upgrading until the problem is solved.
If you are doing a fresh install, then you should be fine with Yii 2.0.5. I will follow up when the problem is solved.
I will also try to carve out time to build my app from scratch with Yii 2.0.5, so that I can have a current build handy for any issues that might arise. I anticipate this will take a couple of weeks as I’m in the process of completing another book, which I will be talking about on this blog.
Also, thanks so much for the great reviews I’ve received on GoodReads.com. Right now we are 4.68 out of 5 stars average with 25 ratings and 7 reviews. I really appreciate all the support I got with this book, so thanks again.
