Lifetime Support Policy for Database Feature Releases
Most feature releases are supported for 2 years after the succeeding release becomes available on on-prem (non-Engineered System) platforms. Periodically, a release is designated as an “Extended Support Release” and is supported for 8 years. The support life of each release is documented in the Lifetime Support Policy document.
Release Version Numbering Changes
Beginning in 2018, a new numbering schema for the database software is implemented. Instead of a legacy nomenclature such as 220.127.116.11, a three (3) field format consisting of: Year.Update.Revision is used, such as 18.1.0. This allows clear indication of:
- the feature release designation of the database software (the first field)
- the quarterly Update (the second field)
- the quarterly Revision (the third field)
