Well, simple_rss is removed from core (I believe yesterday).
Plugin autobot no longer builds.
Is someone interested in picking up the plugin and modify it to work again now that it gets unsupported all of a sudden. Well, not very suddenly, as we had, what, weeks of warning. But IMHO it is still bad form to terminate an official plugin suddenly and render it not working without caring for a smooth transition.
How can we trust other official plugins now?
autobot was never official; only plugins under https://github.com/discourse/ are official.

It should not be difficult to fix, though, if anyone from the community wants to adopt it.
I standard corrected. 
I know it should be easy to fix for somebody with Ruby knowledge, but I don’t know how to add the simple_rss gem back on the plugin.
Perhaps some other Ruby gurus can shed a light here?
I can pick this up, my Ruby/Rails skills is practically non-existent.
Check out this post / topic; should be a simple fix I believe:
I’ll be waiting for someone to fix 
Todavía esperando… esperando…
Estoy seguro de que un post de #mercado pondría las cosas en marcha…
Puedo echar un vistazo a esto cuando tenga un momento. No será este fin de semana, pero posiblemente alguna vez la próxima semana.
Como bien dices, parece una solución sencilla.
¿Que tenga oportunidad? 
Yo no uso este plugin personalmente, así que lo revisaré cuando tenga algo de tiempo libre. Sin embargo, es poco probable que sea dentro de las próximas dos semanas, ya que tengo compromisos previos.
Si necesitas que se haga antes de entonces, te sugiero publicar en Marketplace.
Es algo ‘agradable de tener’, pero no crucial. Creo que podemos esperar…
