OmniOS Release Schedule
Even-numbered releases of OmniOS are stable and odd-numbered releases are unstable (bloody). See stable vs. bloody for more information on the difference between them.
Stable releases come out approximately every six months; around the first week in May and the first week in November. Stable releases are supported for a year after release.
Every fourth stable release is a long-term support (LTS) release. LTS releases are supported for three years and therefore overlap for a year to allow time for validation and upgrade even in complex environments. Regular stable releases overlap for six months.
In the table below, currently supported releases are emboldened.
