This branch was a child fork of JamieMagee teams-for-linux repo, that was itself a fork of Ivelkov teams-for-linux.
Jamie did express his desire to refactor this project in Typescript and to support it, but he has archive the project and I suspect that means he doesn't have the time to support it.
I have tried to contact Ivelkov for a few months but haven't receive any answers.
For that reason, decided to refork it and fix a few things that where not working. The list has grown since then to support many features and to fix most of the bugs.
To be able to use a few github functionalities, it was decided to unfork the project #87.
The original idea was to let the project die when Microsoft would implement a desktop client for linux, as requested on the Microsoft Suggestions Forum. Microsoft released a linux client on February 13, 2020 (Download, Instructions). However, the development of this project continued, as it is suprior on some aspects (screen share able to share single windows, normal window border #281, command-line interface, and, of course, open-source).
Currently, the project is in a stable condition, and should continue as long as needed. Non stable versions are released as pre-release. IsmaelMartinez is not "implementing new features, only fixing issues, but happy to help and accept new PRs" (351).
