 ## Mithril Distribution [2517.0] - 2025-05-05
 
 - **BREAKING** changes in Mithril client CLI and library:
+
   - To fast bootstrap a Cardano node, the new `--include-ancillary` option has been added to the _Cardano node database_ command in the Mithril client CLI.
   - Without this option, only final immutable files are downloaded, and the ledger state must be computed from the genesis block when the Cardano node starts.
   - The `--include-ancillary` option requires the usage of an **ancillary verification key** (`--ancillary-verification-key` or `ANCILLARY_VERIFICATION_KEY`) which is specified in the [Networks configuration](https://mithril.network/doc/manual/getting-started/network-configurations) page.
