In April 2019, ahead of NAB, NewTek announced the addition of Multi-TCP mode to NDI 4.0 which uses hardware [[TCP offload engine]] present in silicon, assisting lower-spec processors with NDI transport.<ref name="nab2019plans">{{Cite web | url=https://www.tvtechnology.com/news/newteks-andrew-cross-talks-about-the-acquisition-discusses-nab-show-plans |title = NewTek's Andrew Cross Discusses Acquisition, NAB Show Plans|first=Phil|last=Kurz|date=April 3, 2019}}</ref> NDI 4.0 shipped in September 2019 to coincide with the IBC exhibition.

In July 2021, NDI 5 was released adding reliable UDP transmission, redundant discovery server support, and NDI 5 Tools (NDI Bridge, NDI Remote, NDI Audio Direct, FCP-X output)<ref>{{Cite web | url=https://www.ndi.tv/tools/ | title=NDI Tools &#124; NDI.tv }}</ref><!--[[User:Kvng/RTH]]-->
