 - `--cardano-node-version`: version used to download the `snapshot-converter` binary (specific version, eg, `10.1.4`, `latest`, or `prerelease`)

+### Distribution `2537` is now available
+
+The [`2537.0`](https://github.com/input-output-hk/mithril/releases/tag/2537.0) distribution has been released, introducing the following changes:
+
+- Added support for Cardano node `v.10.5.1` in the signer and aggregator
+- Added support for the stable `cardano_database_v2` backend in the `mithril-client` library
+- Added support for the stable `v2` backend of the `cardano-db` command, with the decommissioning of the `cardano-db-v2` command in the client CLI
+- Added support for the stable `verify` command to validate an existing Cardano database in the client CLI
+- Added support for the stable UTXO-HD snapshot converter via the tools `utxo-hd snapshot-converter` command in the client CLI
+- Provided pre-built Linux ARM binaries for the signer, client CLI, and aggregator
+- Migrated to the Rust `2024` edition (from the `2021` edition)
+- General bug fixes and performance improvements.
+
+This new distribution has been deployed to the **Mithril aggregator** on the `release-mainnet` and `release-preprod` networks.
+
+For those running a **Mithril signer**:
+
+- **pre-release-preview** network: no action is required at this time
+- **release-preprod** network: upgrade the signer node binary to version `0.2.268` – no configuration changes are required
+- **release-mainnet** network: upgrade the signer node binary to version `0.2.268`– no configuration changes are required.
+
+You can update the Mithril signer using the one-line command below. By default, it downloads to the current directory, but you can specify a custom folder with the -p option:
+
+```bash
+curl --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/input-output-hk/mithril/refs/heads/main/mithril-install.sh | sh -s -- -c mithril-signer -d 2537.0 -p $(pwd)
