# Versioning policy
|
||
|
||
Starting with vLLM 0.7.x, the vLLM Ascend Plugin ([vllm-project/vllm-ascend](https://github.com/vllm-project/vllm-ascend)) project follows the [PEP 440](https://peps.python.org/pep-0440/) to publish matching with vLLM ([vllm-project/vllm](https://github.com/vllm-project/vllm)).
|
||
|
||
## vLLM Ascend Plugin versions
|
||
|
||
Each vllm-ascend release will be versioned: `v[major].[minor].[micro][rcN][.postN]` (such as
|
||
`v0.7.1rc1`, `v0.7.1`, `v0.7.1.post1`)
|
||
|
||
- **Final releases**: will typically be released every **3 months**, will take the vLLM upstream release plan and Ascend software product release plan into comprehensive consideration.
|
||
- **Pre releases**: will typically be released **on demand**, ending with rcN, represents the Nth release candidate version, to support early testing by our users prior to a final release.
|
||
- **Post releases**: will typically be released **on demand** to support to address minor errors in a final release. It's different from [PEP-440 post release note](https://peps.python.org/pep-0440/#post-releases) suggestion, it will contain actual bug fixes considering that the final release version should be matched strictly with the vLLM final release version (`v[major].[minor].[micro]`). The post version has to be published as a patch version of the final release.
|
||
|
||
For example:
|
||
- `v0.7.x`: it's the first final release to match the vLLM `v0.7.x` version.
|
||
- `v0.7.1rc1`: will be the first pre version of vllm-ascend.
|
||
- `v0.7.1.post1`: will be the post release if the `v0.7.1` release has some minor errors.
|
||
|
||
## Branch policy
|
||
|
||
vllm-ascend has main branch and dev branch.
|
||
|
||
- **main**: main branch，corresponds to the vLLM main branch, and is continuously monitored for quality through Ascend CI.
|
||
- **vX.Y.Z-dev**: development branch, created with part of new releases of vLLM. For example, `v0.7.1-dev` is the dev branch for vLLM `v0.7.1` version.
|
||
|
||
Usually, a commit should be ONLY first merged in the main branch, and then backported to the dev branch to reduce maintenance costs as much as possible.
|
||
|
||
### Maintenance branch and EOL:
|
||
The branch status will be in one of the following states:
|
||
|
||
| Branch | Time frame | Summary |
|
||
|-------------------|----------------------------------|----------------------------------------------------------------------|
|
||
| Maintained | Approximately 2-3 minor versions | All bugfixes are appropriate. Releases produced, CI commitment. |
|
||
| Unmaintained | Community interest driven | All bugfixes are appropriate. No Releases produced, No CI commitment |
|
||
| End of Life (EOL) | N/A | Branch no longer accepting changes |
|
||
|
||
### Branch state
|
||
|
||
Note that vllm-ascend will only be released for a certain vLLM release version rather than all versions. Hence, You might see only part of versions have dev branches (such as only `0.7.1-dev` / `0.7.3-dev` but no `0.7.2-dev`), this is as expected.
|
||
|
||
Usually, each minor version of vLLM (such as 0.7) will correspond to a vllm-ascend version branch and support its latest version (for example, we plan to support version 0.7.3) as following shown:
|
||
|
||
| Branch | Status | Note |
|
||
|------------|--------------|--------------------------------------|
|
||
| main | Maintained | CI commitment for vLLM main branch |
|
||
| v0.7.3-dev | Maintained | CI commitment for vLLM 0.7.3 version |
|
||
| v0.7.1-dev | Unmaintained | Replaced by v0.7.3-dev |
|
||
