We adopt the Semantic Versioning of the format as v<major>.<minor>.<build>, e.g. v3.10.7.
Branchs
We are maintaining three minor version branchs at any time:
- Stable: The maintenance branch. We only fix bugs, but do not add any new features. It is currently v3.9.
- Mainline: The currently released branch. we will add minor incremental features and fix BUGs, but do not add new major features or architectural changes. It is currently v3.10.
- Development: The current main development branch. The major new features or architectural changes are developed in the branch. The development branch is always master branch.

The minor versions of each branches will be periodically built and released in the format of docker images. The release cycle is as follow:
- Stable: released in the middle of each month
