This new poster is required of all employers.
With all the changes going on in the government it should be no surprise that new posters have been produced.
Minimum wage
This has nothing to do with the new regulations going into effect on December 1, 2016 this year. This is actually the $7.25 minimum wage poster. It is new, and required, because the government is trying to be technologically more current and thus they have put a QR code on the poster to facilitate your employee finding out information or reporting you to the USDOL. You can download it here. 
Other posters
Along these lines there is also a new Polygraph poster, which can be downloaded here.
There is also a new Family and Medical Leave Poster, required of all companies that have more than 50 employees. It can be downloaded here.
The good thing is that if you have an “All-in-one poster” you can take these posters above that you downloaded and tape them over the comprehensive poster and you are good to go, at least until you decide to purchase a new snazzy plastic poster.
At some point every poster will probably include the QR technology so you may want to wait for those.
