EdgeX Foundry plans to produce and release a new named version (like Delhi, Edinburgh, Fuji, etc.) of EdgeX every six (6) months. Named versions will also have a version number in the form of X.Y (example 1.0 or 2.1). Depending on the features and compatibility with the prior release, the named release may be a major or minor release (see releases, versions and patches), but the semi-annual release schedule gives you, our user community, assurance that new EdgeX features and capability capabilities are delivered at least every six months.
EdgeX Foundry offers a new long-term support (LTS) release every two (2) years. The TSC will select the release (major , or minor , etc.- see Releases, Versions & Patches for definition of releases) for the LTS release.

No new functionality will be added to an LTS release. Only significant security and bug fixes will be added to the LTS. LTS bug fixes (and any new LTS release or patch) must be approved by the EdgeX TSC. An LTS release is meant to be a stable release for which organizations typically base products and for which the EdgeX community offers “support” as defined below.
