Bitcoin ABC will be upgraded to version 0.20.0 with two new features added

On October 7, the Bitcoin ABC team announced that the agreement version will be upgraded in November 2019. BitcoinABC 0.20.0 is now available, and this upgrade will add two new features to the blockchain. The first component added will be Schnorr's support for OP_Checkmultisig, which will allow for more sophisticated mechanisms to handle multi-signature transactions, and all signature check operations will support Schnorr signatures. In addition, the upgrade will ultimately determine the BIP62 ductility vector by enforcing Minimaldata (also known as the "Minimaldata" rule) in the script. This enhancement is designed to make most transactions on the BCH network (including all P2PKH transactions) non-malicious.
