Is the project still alive?

[f4iey]

Background

Not so long ago, I discovered Ludosport and the customization potential for Polaris OPENCORE EVO Sabers.
By digging up a little more, I found this very promising project and as a Arch Linux user btw very curious EE nerd, I wanted to see how it works "under the hood".
However, I cannot understand why there have been no recent commits to the project for more than two years.

Observations

Upon further resource checking, I found that there is a release R10 on the Sabersmithy page, which suggests that the project may still be active.
Despite that, the latest commit on the repo indicates release R7 was the last one.

Concerns

Given that the project is released under GPL3 license, the lack of recent commits raises concerns about its maintenance and compliance with the open-source license. The GPL3 license requires that the source code of any modified or derived work be made available under the same license terms.

That is why I'd like to know what is the current state of the project. Specifically whether it is still maintained, and if not, whether the source code has been made proprietary, which I would be disappointed...

Question: Is the Send-to-Saber project still maintained, or has it been decided to make the source code proprietary, which would be a loss for the open-source community?

Conclusion

It is important that open-source projects like Send-to-Saber are maintained and developed actively to ensure the community can continue to contribute and benefit from them.
One of the main reason I'm asking all this is because I wanted to compile the latest version to make it available on Linux.

I am just trying to understand what happened.
