This is goooood news..
As of the release of Core 0.11.2 OP_CHECKLOCKTIMEVERIFY is now becoming a reality.
This has major implications, as it means that REFUND TXNs now work. Without having to worry about TXN malleability.
So that lots and lots of clever smart contracts can be written and used, that were more like fantasy stories a mere couple of months ago..
For me, the BIG ONE, is Atomic Cross Chain Transfers.
We can now finally see the light at the end of the 'Trust-Free 100%-Secure Crypto-Exchange' tunnel. (Crypto, not FIAT, as FIAT
always requires trust)
Lots of other uses too. (Lightning Network is another..)

Just wanted to pass that info on..
