This release is a major release which is compatible with the Bitcoin Cash compatible with the Bitcoin Cash specifications you could find here:

• https://github.com/bitcoincashorg/bitcoincash.org/blob/master/spec/uahf-technical-spec.md (Aug 1st '17 Protocol Upgrade)
• https://github.com/bitcoincashorg/bitcoincash.org/blob/master/spec/nov-13-hardfork-spec.md (Nov 13th '17 Protocol Upgrade)
• https://github.com/bitcoincashorg/bitcoincash.org/blob/master/spec/may-2018-hardfork.md (May 15th '18 Protocol Upgrade)
• https://github.com/bitcoincashorg/bitcoincash.org/blob/master/spec/2018-nov-upgrade.md (Nov 15th '18 Protocol Upgrade)

This release will also implement a set of consensus changes proposed by an alternative implementation, Bitcoin SV, see SV release notes for ver 0.1.0 for more details. Such set of features is disabled by default, the default policy is to activate the set of changes as defined by the bitcoincash.org specification.

To configure your BUcash client so that it will activate the protocol upgrade proposed by SV you need to add consensus.forkNov2018Time=0 and consensus.svForkNov2018Time=1 in your bitcoin.conf file. Trying to activate both protocol upgrades at the same time will lead to the client to exit with this error message: Both the SV and ABC forks are enabled. You must choose one.

List of notable changes and fixes to the code base:

• Implementation of Bitcoin SV November 2018 features (see the SV upgrade specifications), disable by default
  • OP_MUL, OP_INVERT, OP_LSHIFT, OP_RSHIFT
  • Increase max number of op_codes per script to 500
  • Increase max block size to 128MB
• Turn graphene on by default
