Simon Long představil na blogu Raspberry Pi novou verzi 2017-06-21 linuxové distribuce Raspbian určené především pro jednodeskové miniaturní počítače Raspberry Pi. Společně s Raspbianem byl aktualizován také instalační nástroj NOOBS (New Out Of the Box Software). Z novinek lze zdůraznit IDE Thonny pro vývoj v programovacím jazyce Python a především offline verzi Scratche 2.0. Ten bylo dosud možné používat pouze online. Offline bylo možné používat pouze Scratch ve verzi 1.4. Z nového Scratchu lze ovládat také GPIO piny. Scratch 2.0 vyžaduje Flash.
