Looks like this https://github.com/kitabisa/teler-v3 is the planned version. There's a v2 listed in their GitHub as well they mention us current.
At the very beginning of the Readme file, you can see the state of the project.
"The development of teler IDS is currently on hold. However, we're thrilled to inform you that we've decided to take a bold step by embarking on a complete refactor, starting from scratch to enhance the overall development process."
Starting from scratch is the exact opposite of “refactor”. What they may have meant is “redesign”.
