@pedrominatel In the page that you updated, there is also a section called Previous edition which includes DevCon24.

Why only one previous edition? Why not mention all previous editions there?

Added the links for the 23 and 22 editions.

I see that in the past event, the announcements remained.
Shall we update also the other events (e.g. Embedded world 2025)?

If we have content to show, such as videos or any other type of material, we need to update it. Otherwise, there is no need to make any updates.
