Celestia validators asked to run celestia-app v10.6.0; celestia-node v0.35.0 follows on mainnet

Celestia asked mainnet operators on 9 November 2026 to upgrade consensus nodes and Fibre to v10.6.0 as soon as possible. The release carries consensus, p2p, proof and Fibre fixes. celestia-node v0.35.0 reached mainnet on 12 November.

On 9 November 2026 at 09:39 UTC, Celestia's status page asked Mainnet Beta operators to upgrade their consensus nodes and Fibre to celestia-app v10.6.0 "as soon as possible". The notice sets no deadline and does not call the upgrade mandatory. It is not a network upgrade with an activation height: each operator installs it on their own schedule. It is the mainnet counterpart of v10.6.0-mocha, which went to the Mocha testnet on 5 November (earlier post).

What changes in v10.6.0

  • celestia-core goes from v0.42.5 to v0.42.8. That brings fixes to consensus block propagation, the CAT mempool, p2p peer identity validation and the JSON-RPC server. tx_search and block_search now apply the result limit to the whole query.
  • Proofs: ShareProof and RowProof verification now checks each proof's position in the data square. Celestia says clients that verify proofs, such as celestia-node, should use this release's packages.
  • Fibre: MsgDepositToEscrow transactions with a non-canonical signer address, or a denom other than utia, are now kept out of the mempool and new proposals. Blocks that already contain them stay valid. The Fibre client also no longer crashes on incomplete state node responses.
  • Hyperlane and IBC: hyperlane-cosmos moves to v1.3.3 with stricter ECDSA signature and ISM routing checks, and the IBC capability module moves to a fork that is safe for concurrent use.

celestia-node v0.35.0

celestia-node v0.35.0 followed on Mainnet Beta on 12 November 2026, in a window from 10:30 to 10:45 UTC, a day after v0.35.0-mocha reached the Mocha testnet. It replaces Bitswap with shrex, adds JWT token revocation and includes security and stability fixes. No coordinated upgrade is required. Source builds need Go 1.26.10 or later, and the release notes describe a recommended config update.

What it means

Validators: v10.6.0 is a maintenance release, but it touches consensus networking, the mempool and p2p identity checks, so it is worth installing soon. Fibre servers need the upgrade too: 77 of 98 active validators have one registered on chain.

Bridge, full and light node operators: plan the move to v0.35.0 and its config change.

Delegators: nothing to do. This is separate from the coming v11 upgrade, which will cap gas from non-blob transactions and has no date yet.

Network health is on BitBasic's Celestia dashboard.
