However, on April 12, 2017 iXsystems announced that FreeNAS Corral would instead be relegated to being a 'Technology Preview', citing issues such as "general instability, lack of feature parity with 9.10 (Jails, iSCSI, etc), and some users experiencing lower performance than expected" and the departure of the project lead. Instead, the decision was made to revert to the existing 9.10 code and bring Corral features to 9.10.3 and further.
In May 2017, iXsystems announced that FreeNAS 11 would be imminently released, which was based on 9.10 but included features such as an update of the FreeBSD operating system,

In March 2020, iXsystems announced that the 12.0 release will merge the FreeNAS code base with that of their commercial TrueNAS offering. FreeNAS will become TrueNAS CORE while TrueNAS will be renamed TrueNAS Enterprise. This change was made official with the release of TrueNAS 12.0 on October 20, 2020.
In October 2020, iXsystems announced a new product, TrueNAS SCALE would be developed. TrueNAS SCALE would still utilize ZFS, but be based on Debian Linux.
In February 2022, iX announced that TrueNAS SCALE has reached General Availability quality for their 22.02 release.
In May 2022, iX announced that TrueNAS CORE, their FreeBSD Based version of TrueNAS, has reached General Availabilty and is suitable for large deployments.
