python-bitcoinlib (0.9.0-1) unstable; urgency=medium
  From upstream changelog:
   Now supports segwit, which breaks the API in minor ways from v0.8.0. This
   version introduces lots of new API functionality related to this, such as the
   new `CScriptWitness`, `CTxInWitness`, `CTxWitness`, new sigwit-specific logic
   in `SignatureHash()` etc.
  Now the RPC interface, bitcoin.rpc, is designed to work with
  Bitcoin Core v0.15.0

python-bitcoinlib (0.8.0-1) unstable; urgency=medium

  Major breaking API change:
  Method CTransaction/CMutableTransaction GetHash() has been renamed to GetTxid
  to prepare for a future segwit-enabled release. Calls to GetHash() function
  will raise AttributeError.
  Since this release doesn't yet include segwit support, you will need to set
  the Bitcoin Core -rpcserialversion=0 option, either as a command line argument
  or in your bitcoin.conf file. Otherwise the RPC interface will return
  segwit-serialized transactions that this release's RPC support doesn't
  understand.
