Arduino core for the tinyAVR 0/1/2-series - Ones's digit 2,4,5,7 (pincount, 8,14,20,24), tens digit 0, 1, or 2 (featureset), preceded by flash in kb. Library maintainers: porting help available!
2-series parts will need optiboot compiled with appropriate options. I believe the only differences should be the support for second UART.
Board manager entries will be slightly different:
TCD0 removed
TCB1 note about applicable parts removed
UPDI/Reset pin menu adjusted for 20/24-pin parts, alternate reset will be the first/default option now, making these the first modern tinyAVR parts where Optiboot's UX won't be utter crap or a high-stakes game (well, the cost of a chip and board to mount it on, which is only high stakes in relative terms) for those who don't have a HV UPDI programmer.
