Hello Maria! Hello everyone!

Thank you all for your efforts!
As far as possible, I will conduct practical tests within the scenarios
where I use BIRD.

I was reviewing the roadmap file in docs:
https://gitlab.nic.cz/labs/bird/-/blob/v3.2.1/doc/roadmap.md
https://gitlab.nic.cz/labs/bird/-/blob/v3.1.6/doc/roadmap.md
https://gitlab.nic.cz/labs/bird/-/blob/v2.18.1/doc/roadmap.md
https://gitlab.nic.cz/labs/bird/-/blob/v2.17.4/doc/roadmap.md

And I believe that roadmap.md is feeling a bit lonely.
At least, the "Planned for 2025" is looking at me with sad eyes. Rsrsrs

I'm not sure if my line of reasoning is correct:
But I imagine support for new features isn't a priority in version 2.X.X.
It only comes into play under specific demands or when the code for tha
feature in 3.X.X fits almost perfectly into 2.X.X.
Does that make sense?

Considering the large number of recent RFCs that are somehow covered for
the scope of the BIRD, would you consider providing a more detailed
overview of the annual or semi-annual plan?


And to finish...
I'm still eagerly awaiting the continuation of those stories about how the
transition process from Bird 2 to Bird 3 was and is going.
