This release of Hammer contains a major refactoring of the code for publishing to PyPI (#675). Compatibility is broken with pre-v1.0.0 Hammer plugins and flows as a result--for backwards compatibility, please use the v0.1.0 tag, but note that features will not be backported.
Please refer to the new setup guide for how to use this new version of Hammer. There is also a simple migration guide for how to update your Hammer IR and tech/tool plugins.
Going forward, please use Github's Discussions feature for general support. Please file an issue if you believe there is a bug.
