Note!
I will no longer be maintaining this answer, because Google is doing a very good job at doing the releases now. With a post on their Android Developers Blog, official release notes and often also a video on their YouTube channel with a short overview of what's new.
I'll leave the last two (as of writing) updates and the original answer. Please find the previous updates here

Original answer
They have just been released (see the highlights). You can find more information on how to use the granular dependencies here.
You will need to update your local Google Play Services repository using the SDK Manager provided by the SDK or use a plugin like Jake Whartons sdk-manager-plugin for Gradle which will automatically update it for you. It would look like this when building with Gradle:
Google Play Services repository outdated. Downloading update...

As of writing, the second link seem to be corrupt, as in, even though Using Android Studio is selected in the drop down menu, it doesn't show the information, at least for me. In order to see the information for Android Studio, select Using something else, then select Using Android Studio again.

Google just made a blog post about Google Play Services 6.5 and the 65k method limit. It contains the information of my post and more. I'll just quote one paragraph for anyone who comes across this information via SO instead of the blog post:
Note: At the time of writing, the correct version to use is 6.5.87. As this is a very granular number, it will get updated quite quickly, so be sure the check the latest version when you are coding. Often people will use a ‘+’ to denote versions, such as 6.5.+ to use the latest 6.5 build. However, it’s typically discouraged to use a ‘+’ as it can lead to inconsistencies.
