CELESTIA-APP v8.0.1-mocha — Mocha upgrade

Dear partners and node operators,

We are pleased to announce a new version of celestia-app today. Please upgrade as soon as possible to benefit from the latest features and fixes.

Celestia-app:

This release is intended for Mocha. If you are upgrading from v6 or v7, please read through the release notes carefully

Important changes:

• minimum OS version required for v8 is Ubuntu 24.04 or later

• forwarding address derivation: v8 binds the token identity to forwarding address derivation in `x/forwarding`. Frontends and relayers select the token route off-chain and the module verifies it matches the derived address. Each unique (`destDomain`, `destRecipient`, `tokenId`) tuple now derives its own forwarding address. Any assets sent to a forwarding address with a mismatched denomination are irrecoverable by design. Existing forwarding addresses derived without the token identifier will no longer be valid.

For more information, please check the release notes.

If you are an active validator:

Please signal to upgrade to v8:

• `celestia-appd tx signal signal 8 --from (validatorwallet) --chain-id mocha-4 --fees 210000utia`

• You can track the tally of signaling by validators using the following query `celestia-appd query signal tally 8`

• Once 5/6+ of the voting power have signaled, the upgrade will be ready.

• There is a hard coded delay between confirmation of the upgrade and execution to the new state machine.

• To view the upcoming upgrade height use the following query: `celestia-appd query signal upgrade`

• The upgrade delay is `2 days` after 5/6+ voting power has signaled and the upgrade tx is submitted
