No, I was thinking of the height in coinbase change. At any rate, p2sh was supported by the consensus code in bitcoinj for a long time already, since it was first written.

Support for sending to such addresses in the wallet appeared once an app that wanted that support also appeared, which seems OK - the market for wallets is very competitive so there will always be some skew in what features are worked on in what order. V3 transactions are a consensus change that wallets will pick up at different times like any other feature.

You mean P2SH... which your implementation has only picked up support
for in the last month or so?
