| Component     | Network-compatible release                                                   | Used by                                          |
| ------------- | ---------------------------------------------------------------------------- | ------------------------------------------------ |
| celestia-app  | [v10.5.0](https://github.com/celestiaorg/celestia-app/releases/tag/v10.5.0)  | Consensus and validator nodes                    |
| Fibre         | [v10.5.0](https://github.com/celestiaorg/celestia-app/releases/tag/v10.5.0)  | Bonded validators; matching celestia-app release |
| celestia-node | [v0.34.3](https://github.com/celestiaorg/celestia-node/releases/tag/v0.34.3) | Light and bridge nodes                           |

The celestia-app and Fibre targets follow the [v10.5.0 release](https://github.com/celestiaorg/celestia-app/releases/tag/v10.5.0). The celestia-node entry is separate from this app release. These are documentation targets, not a measurement of the versions running on BlockPro servers.

## What changes in v10.5.0

Upgrade celestia-app and Fibre together using the matching network tag. Fibre adds a `[health]` table and gRPC readiness checks. Configured object-storage endpoints must use HTTPS, and the bucket must be accessible with the service credentials at startup. See [Fibre](/mainnet/celestia/validator-node/fibre.md) for configuration and checks.

## Check your installation

Print the installed consensus binary version.

```bash
celestia-appd version
```

Print the installed Fibre version on the Fibre host.

```bash
fibre version
```

Print the installed DA binary version.

```bash
celestia version
```

Read the active application version from your running node.

```bash
curl -fsS http://127.0.0.1:26657/abci_info | jq -r '.result.response.app_version'
```

Mainnet app v10 is live. Confirm that your synchronized node reports active app version 10 or later before starting [Fibre](/mainnet/celestia/validator-node/fibre.md) and registering its host. The installed binary and active chain version are different checks. Retain the multiplexer for supported historical replay; do not use a standalone build or Cosmovisor for the v9-to-v10 transition.

Use the matching v10.5.0 Fibre binary for remote-signing mTLS and object-storage support. For local plaintext signing, use `127.0.0.1:26669` or `[::1]:26669`; `localhost` is not accepted as a loopback exemption.

The install guide and compatibility table can update at different times. Use the network compatibility table and the release notes together before changing a production node.
