WordPress just released version 4.7.1 which is a Security and Maintenance release. This means that they have found and fixed various security vulnerabilities.
In order to take full advantage of this release, it’s suggested that you update your WordPress core to 4.7.1. There are some situations where you may not want to update, such as if your theme doesn’t support 4.7.x. I highly suggest looking into this and updating as soon as you are able.
