DisplayPort 1.4, released March 2016, kept the same 32.4 Gbps HBR3 link rate as 1.3 but added Display Stream Compression (DSC) 1.2 -- a visually lossless compression scheme that extends the same bandwidth to resolutions like 8K at 30Hz that wouldn't otherwise fit.

HDMI 1.4, released in 2009, added the HDMI Ethernet Channel, Audio Return Channel (ARC), and stereoscopic 3D video support, plus a 4K mode -- but capped at 24-30Hz, since bandwidth stayed at 10.2 Gbps. The even smaller Type D Micro connector was also introduced.
