Google Admin has recently received its first update of the year. If you aren't the administrator for a Google for Work account, then there's nothing here for you to sink your teeth into. But there are a few new features here for people on the management side of things.
Administrators can now implement a 4-digit PIN that works on numerous devices. This way you could have all of the spare tablets in a college IT department, for example, secured with the same code that gets changed every week or so.
