oday Bitcoin Cash activated a hard fork that will increase the BCH block size from 8MB to 32MB and add new OP codes to the codebase.

Bigger Blocks
Initially announced November 2017, the upgrade began at 12:00:00 UTC when the hard fork was initialized.

As CCN reported back in April, the fork includes the addition of OP codes, which allow smart contract capabilities.
However, the whopping increase in block size has drawn the most attention. Blog updates about the Bitcoin Cash hard fork remain optimistic that the upgrade will reduce transaction fees, but critics allege that there are potential downsides to quadrupling the block size, as concerns over the security of large block sizes still loom.
