Release Announcement Bitcoin Classic 1.3.3

August 3st, 2017.

Bitcoin Classic updates the 1.3 version to add the ability to switch a datadir from BTC to the BCC chain.

As the latest in the crazy week of Classic releases in relation to the successful Bitcoin Cash creation, here is a brief overview of what the 1.3 version of Bitcoin Classic adds.

  • Full Bitcoin Cash support, using the UAHF name. A special download is available.
  • Ability to automatically migrate and separate out the Bitcoin Cash data from the traditional chain. This allows users to run two nodes, each following a different chain.
  • Faster re-connecting to Bitcoin Cash capable nodes by remembering which nodes support it.
  • Full zero-fee transaction support. From relay for others as well as creation in the wallet and mining.
  • Much improved log-file support. Including runtime reloading of config-file using SIGHUP.
  • Won't crash on asserts because we restored sanity, asserts are not part of release builds.

This client is fully compatible with the Bitcoin Cash spin-off from Bitcoin, but using the default settings we ignore it. You can change the config-file, or we point you to the specialized UAHF version of Classic.
