The 3GPP press release mentioned the following:LTE-Advanced Pro will allow mobile standards users to associate various new features – from the Release’s freeze in March 2016 – with a distinctive marker that evolves the LTE and LTE-Advanced technology series.
The new term is intended to mark the point in time where the LTE platform has been dramatically enhanced to address new markets as well as adding functionality to improve efficiency.
The major advances achieved with the completion of Release 13 include: MTC enhancements, public safety features – such as D2D and ProSe - small cell dual-connectivity and architecture, carrier aggregation enhancements, interworking with Wi-Fi, licensed assisted access (at 5 GHz), 3D/FD-MIMO, indoor positioning, single cell-point to multi-point and work on latency reduction. Many of these features were started in previous Releases, but will become mature in Release 13.

Some vendors have been exploring ways of differentiating the advanced features of Release-13 and have been using the term 4.5G. While 3GPP does not officially support 4.5G (or even 4G) terminology, a new term has been welcomed by operators and vendors alike.
I blogged about Release-13 before, here, which includes a 3GPP presentation and 4G Americas whitepaper. Recently Nokia (Networks) released a short and sweet video and a whitepaper. Both are embedded below:
