########## contribute/release-policy.md: ########## @@ -0,0 +1,94 @@ +--- +id: release-policy +title: Release policy +--- + +## Release semantics + +The Pulsar project follows a variant of [Semantic Versioning](http://semver.org/spec/v2.0.0.html). Existing releases can expect patches for bugs and security vulnerabilities. New features will target minor releases. The difference is that a major version bump will not carry any special meaning in terms of "big features" included in the release or breaking API changes. Instead, it would simply signal a new long-term support (LTS) release. + +For example, + +* 2.10.0 is a feature release; +* 2.10.1 is a patch release; +* 2.11.0 is a feature release; +* 3.0.0 is the first LTS release; +* 3.1.0 is a feature release; +* 3.2.0 is a feature release; +* 3.2.1 is a patch release; +* 4.0.0 is a LTS release. + +## Compatibility between releases + +When upgrading an existing cluster, it is important to upgrade components linearly. + +Before 3.0, upgrade should be done linearly through each minor version. For example, when upgrading from 2.8 to 2.10, it is important to upgrade to 2.9 before going to 2.10.
