In the highschool we're working with Minecraft for Raspberry Pi (also known as MCRP) to learn ruby.
I searched a little bit around the web, and I found the official page of it (pi.minecraft.net) and I discovered the last post was over 3 years ago.
No post on Mojang's blog about MCRP has been posted since its announcement. The developer of MCRP is the same of MC:PE.
Is Minecraft for Raspberry PI discontinued?
