Grin (node) v4.1.0 has been released.
Release notes - https://github.com/mimblewimble/grin/issues/3445
This is a minor release. No significant new features to call out.
Lots of cleanup and code quality improvements.
This release bumps the supported protocol version of the node, indicating support for “commit only” inputs in blocks and transactions. Nodes continue to be backward compatible with prior protocol versions.
As always, please reach out here or in keybase if you experience any issues or unexpected behavior.
