Arabica upgrade: CELESTIA-APP v9.0.2-arabica and CELESTIA-NODE v0.31.1-arabica

Dear partners and node operators,

We are pleased to announce new versions of celestia-app and celestia-node today. Please upgrade as soon as possible to benefit from the latest fixes and improvements.

Celestia-app:

This release is intended for Arabica. If you are upgrading from v8, please read through the release notes carefully.

This release mainly reduces the block times to 3s.

Setting min-retain-blocks to a non-zero value enables pruning and may increase syncing time while existing data is pruned.

Celestia-node:

This release adds support for celestia-app v9 and reduces network block time to 3s. Once the v9 activation height takes place, upgrading to this version is required.

⚠️ Action Required: run config-update!

This release adds new config fields. After upgrading the binary and before starting your node, run:

celestia bridge config-update --p2p.network arabica

or

celestia light config-update --p2p.network arabica

Please read release notes carefully for other key highlights and changes. ⚠️
