LTS is an abbreviation for “Long Term Support”.


Unless otherwise determined by the EdgeX TSC, any EdgeX LTS release will reach end of its maintenance commitment ("end of life") after two and a half (2.5) years.  Note:  the intention of the 1/2 year allows some overlap between the 2 year LTS cycle.

Support is defined as:

  • Community members best effort and development priority to fix a security or system bug or major flaw (as determined by the project’s appropriate working group chairperson(s) in consultation with the release manager) as soon as possible.
  • Availability of the source code, test code and artifacts, and program artifacts such as micro service executables, shared libraries, container images (Docker), packages (snaps), etc. through the support period that were created and made available at the time of the release.
  • Availability of the platform documentation through the support period that were created to explain and operate the release and all associated artifacts that were made available at the time of the release.Subject to legal restrictions, make available any supporting 3rd party component used by EdgeX as part of the release.  Examples include MongoDB, Consul, Kong, Vault, any 3rd party library, etc.  Where possible, EdgeX will provide archived binaries of the 3rd party components (MongoDB, Redis, Consul, Kong, Vault, etc.) used with LTS versions of EdgeX.  Where possible, EdgeX will also keep an archive snapshot of 3rd party source code used in the creation of LTS versions of EdgeX (ex:  code in the vendor directory of Go Lang repositories).

EdgeX will not offer support around 3rd party products.  For example, EdgeX will not fix bugs or address issues directly associated to the 3rd party code like Kong, Vault, Consul, etc.

Additional professional support (LTS or STS) may be provided by other members of the EdgeX Foundry community.  The EdgeX Foundry project and Linux Foundation can provide connections to providers as necessary.
