The CU8 for AX2012 R3 has been released. You can read the announcement over here.
It’s worth reviewing the list of fixes and if you are working on a new implementation of AX2012 R3 then you should plan to include this before your next testing cycle so you have all the latest hotfixes before you go-live.
The list of features improvement is great around retail, updates to the WMS/TMS modules, trade allowance updates, procurement RFQ updates.
As you can see in the link above, you can leverage Lifecycle Services to do the update.
