This is Release Candidate 1 for v0.17.1
There are major new features, significant changes, and numerous bug fixes. Those running the BTG Core Wallet as a personal wallet or as a stand-alone node can simply shut down their current node and install v0.17.1RC1 in place after backing up their wallet files. Remember, this is still a Release Candidate and there may still be bugs to be discovered.
Those using their node for more complex services, including for mining pools, need to be aware of changes to APIs and how the configuration files are parsed. See the v0.17.1 Announcement blog post for a summary and the release notes for details.
