Is Google changine their algorithm again?

There's been a lot of indexing issue lately. Although Google has reportedly said that the latest bug has been fixed. But I am not sure how much it has effected the SERP's. If its fixed then everything should get back to normal, right?

But its not. Many sites which uses mobile page redirects have been facing a hard time indexing. And not to mention if your site uses a lot of 301 redirects then you might have got effected too.
