On May 31, 2021 we will be moving the v4.4 release of the On-Prem/SDK platform to be officially an unsupported version. This means we will no longer address bugs identified on that version, therefore halting Service Packs from being released against that version.
As with all SDK releases, we publish a planned sunset date on our site, typically years ahead of the official sunset date: https://webhelp.episerver.com/latest/en/b2b-commerce-sdk/productlifecycle/productversions/supportedversions.htm.
If you have any questions or concerns, please contact your Customer Success Manager.
