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.
I don’t use this plugin myself so I’ll get to it when I have some free time. Unlikely to be within the next two weeks though as I have prior engagements.
If you need it done before then then I’d suggest posting in marketplace
