According to ChainCatcher news, the Solana-based mining project ORE officially announced the upgrade to Steel v2. According to the GitHub documentation, Steel is a new Solana smart contract framework that provides utility functions, macros, and code pattern libraries for building secure and maintainable smart contracts on the Solana blockchain.
Additionally, the upgrade window from v1 to v2 has now closed, with over 75% of eligible tokens choosing to upgrade, which the official considers a sign of a successful hard fork.
