We are glad to see that you're interested in knowing further about our news update. But equally, we understand that you have worries regarding a possible change to our Open Source model. TaigaNext will be a big leap in comparison to our current version of Taiga, however the core will remain Open Source.
Taiga is currently developed by a professional team of designers and developers who are all part of Kaleidos Open Source. At Kaleidos, open source is at the core of our values and it will not change. Luckily, we have been funded with a big seed round of 2,2M€ to boost and continue the development of Taiga (as well as our other sister product, Penpot https://penpot.app/). You can read further on our Kaleido's blog post. https://blog.kaleidos.net/Taiga-and-Penpot-lead-our-new-chapter-at-Kaleidos/
In the near future we will further elaborate and communicate what our exact plans are. In the meantime you can deploy Taiga with no risks of discontinuity of any functionality.
Hope we've answered your queries and worries, but feel free to ask anything you need.
Have a great day!
