Lettuce Versions

Open Source Commitment

Lettuce is open source and will stay open source under the Apache License 2.0.

Open Source Support

Lettuce is developed and supported by individuals as open-source project that is not part of their primary occupations. If you need support when planning to use or while using Lettuce, then the open source eco-system is your best primary option to get support. Get in touch with us if you require options beyond regular open-source support.

Maintenance Phases

Software is subject to change during its whole lifetime. Lettuce ships upgrades as it makes sense to push out a release. Each released version has a maintenance phase attached to it which are explained in the table below.

Phase Definition	Services Terms and Conditions
General Support	General Support means maintenance updates and upgrades, bug and security fixes, and active technical assistance within the community General Support also includes security vulnerability resolutions and critical bug fixes in all supported Minor versions, while other maintenance is applied only to the latest supported Minor Release. General Support begins on the date a Major Release enters General Availability for at least 12 months after the initial release.
Technical Guidance	Technical Guidance is available when General Support ends, typically after reaching end of life of a release line. Users may continue to access self-service such as Stack Overflow or [GitHub Discussions](https://github.com/lettuce-io/lettuce-core/discussions).

Maintenance phase transition between releases:

• A Major release begins a new General Support phase for the newly released major version line

• A Minor release and a patch release transition the current versions of the line into Technical Guidance phase so the newly released version is now in General Support.
