The GRIN hard fork was successfully completed on 2019-7-17. The GRIN wallet has been upgraded to version 2.0.0 and the C29 algorithm upgrade has also completed.
GRIN miners on the C29 algorithm need to update their mining software, as the previous versions of the ming software are no longer supported. The following GRIN software is supported: NBMiner 24.1, Bminer 15.7.1, GMiner1.51 and MinerOS.

Note: GRIN mining with the C31 algorithm is not impacted by this hard fork.
