### RPC and REST
Asm script outputs now contain OP_CHECKLOCKTIMEVERIFY in place of OP_NOP2
-------------------------------------------------------------------------
OP_NOP2 has been renamed to OP_CHECKLOCKTIMEVERIFY by [BIP
65](https://github.com/bitcoin/bips/blob/master/bip-0065.mediawiki)
The following outputs are affected by this change:
- RPC `getrawtransaction` (in verbose mode)
- RPC `decoderawtransaction`
- RPC `decodescript`
- REST `/rest/tx/` (JSON format)
- REST `/rest/block/` (JSON format when including extended tx details)
- `bitcoin-tx -json`
### Configuration and command-line options
### Block and transaction handling
