someone235 then announced the v2.0.0 release containing Toccata hardfork activation logic. The activation is scheduled for DAA score 474,165,565, expected around June 30, 2026 at 16:15 UTC, and the announcement told node operators, miners, pools, exchanges, indexers, wallets, and infrastructure providers to upgrade before activation.

The announcement framed Toccata as a major L1 expansion: native covenant support through transaction introspection, covenant IDs for continuity across UTXO transitions, L1 ZK proof verification through OpZkPrecompile, and partitioned sequencing commitments for based ZK applications. (source)
coderofstuff captured the human side of the release after v2.0.0 went out: "At last, the v2.0.0 is out, Toccata is set to activate. Just for a little bit, we can all stop to catch our breaths." (source)
