'''Version 4.2''', published on February 12, 2020, extends NV-DDR3 I/O speeds to 1333MT/s, 1466MT/s and 1600MT/s. The BGA-252b four channel package is introduced which has a smaller footprint than the existing BGA-272b four channel package. To enable higher IOPS multi-plane operations, addressing restrictions related to multi-plane operations are relaxed.<ref>{{Cite web|date=2020-02-12|title=Open NAND Flash Interface Specification Revision 4.2|url=https://media-www.micron.com/-/media/client/onfi/specs/onfi_4_2-gold.pdf}}</ref>
'''Version 5.0''', Published in May of 2021, ONFI5.0 extends NV-DDR3 I/O speeds up to 2400MT/s. A new NV-LPDDR4 lower power interface is introduced with speeds up to 2400MT/s. With the NV-LPDDR4 interface, an optional Data Bus Inversion (DBI) feature is defined. New smaller footprint BGA-178b, BGA-154b and BGA-146b packages are added. ONFI5.0 also includes other errata related to the ONFI4.2 specification. <ref>{{Cite web|last=|first=|date=25 May 2021|title=Open NAND Flash Interface Specification Revision 5.0|url=https://media-www.micron.com/-/media/client/onfi/specs/onfi_5_0_gold.pdf
