| ## Long Term Support | |
| `<a id="lts"></a>` | |
| Fastify's Long Term Support (LTS) is provided according to the schedule laid out | |
| in this document: | |
| 1. Major releases, "X" release of [semantic versioning][semver] X.Y.Z release | |
| versions, are supported for a minimum period of six months from their release | |
| date. The release date of any specific version can be found at | |
| [https://github.com/fastify/fastify/releases](https://github.com/fastify/fastify/releases). | |
| 2. Major releases will receive security updates for an additional six months | |
| from the release of the next major release. After this period we will still | |
| review and release security fixes as long as they are provided by the | |
| community and they do not violate other constraints, e.g. minimum supported | |
| Node.js version. | |
| 3. Major releases will be tested and verified against all Node.js release lines | |
| that are supported by the [Node.js LTS | |
| policy](https://github.com/nodejs/Release) within the LTS period of that | |
| given Fastify release line. This implies that only the latest Node.js release | |
| of a given line is supported. | |
| 4. In addition to Node.js runtime, major releases of Fastify will also be tested | |
| and verified against alternative runtimes that are compatible with Node.js. | |
| The maintenance teams of these alternative runtimes are responsible for ensuring | |
| and guaranteeing these tests work properly. | |
| 1. [N|Solid](https://docs.nodesource.com/nsolid), maintained by NodeSource, | |
| commits to testing and verifying each Fastify major release against the N|Solid | |
| LTS versions that are current at the time of the Fastify release. | |
| NodeSource guarantees that Fastify will be compatible and function correctly | |
| with N|Solid, aligning with the support and compatibility scope of the N|Solid | |
| LTS versions available at the time of the Fastify release. | |
| This ensures users of N|Solid can confidently use Fastify. | |
| A "month" is defined as 30 consecutive days. | |
| > ## Security Releases and Semver | |
| > | |
| > As a consequence of providing long-term support for major releases, there are | |
| > occasions where we need to release breaking changes as a _minor_ version | |
| > release. Such changes will _always_ be noted in the [release | |
| > notes](https://github.com/fastify/fastify/releases). | |
| > | |
| > To avoid automatically receiving breaking security updates it is possible to | |
| > use the tilde (`~`) range qualifier. For example, to get patches for the 3.15 | |
| > release, and avoid automatically updating to the 3.16 release, specify the | |
| > dependency as `"fastify": "~3.15.x"`. This will leave your application | |
| > vulnerable, so please use with caution. | |
| ### Security Support Beyond LTS | |
| Fastify's partner, HeroDevs, provides commercial security support through the | |
| OpenJS Ecosystem Sustainability Program for versions of Fastify that are EOL. | |
| For more information, see their [Never Ending Support][hd-link] service. | |
