All
v3.16.0
Transaction builds can be pinned to a block, so a preview matches a simulation at the same block.

Vaults on Base can borrow from the Compound V3 USDC market and value the position through the price oracle.
v3.14.0 – v3.14.1
Event history can be read from an indexer, and revert errors from newer node software are recognised.
v9 on Ethereum
New vaults on Ethereum get an emergency pauser and can batch their rewards flow into one transaction.
v3.13.0
New tool: vault_validate checks a vault's configuration, the MCP twin of fusion vault validate.
v3.11.1 – v3.13.0
New fusion vault validate command, and public JSON APIs for vault information and Morpho markets.
