## Versioning

- We use [Semantic Versioning](https://semver.org) for releases.
- A new Leon module creation increases the MINOR version number of its relevant Leon package.
- Each time a MAJOR or MINOR version number of a Leon package is increased, then the MINOR version number of the project should also be increased.
- Each time a PATCH version number of a Leon package is increased, then the PATCH version number of the projet should also be increased.

## Sponsor

You can also contribute by [sponsoring Leon](http://sponsor.getleon.ai).

Please note that I dedicate most of my free time to Leon.

By sponsoring the project you make the project sustainable and faster to develop features.

The focus is not only limited to the activity you see on GitHub but also a lot of thinking about the direction of the project. Which is naturally related to the overall design, architecture, vision, learning process and so on...
