CELESTIA-NODE v0.32.1-mocha — Mocha upgrade, mocha-5 DA network is live

Dear partners and node operators,

The mocha-5 DA network is live. We are pleased to announce a new version of celestia-node for Mocha today. Bridge, full, and light node operators should upgrade to v0.32.1-mocha and re-initialize against mocha-5. Please upgrade as soon as possible to benefit from the latest fixes and improvements.

Celestia-node:

This release contains breaking changes.

• The deprecated da Go package and da.* JSON-RPC namespace have been removed. Integrations still calling da.* methods must be updated before upgrading.

• The Arabica network has been removed from celestia-node. Arabica operators should remain on v0.31.x.

• The mocha network now resolves to mocha-5. Mocha-5 is a new chain starting at height 1 — mocha-4 stores cannot be reused, and the default store path changes with the network, so a fresh init is required.

• Bridge nodes must set --core.ip to a mocha-5 consensus node. Mocha-4 endpoints will not work.

New in this release:

• Bridge nodes can ingest blocks from multiple core endpoints and keep operating as long as one stays healthy. Additional endpoints are configured in config.toml under [[Core.AdditionalCoreEndpoints]].

• Reduced memory usage in the shrex client, and new metrics for observability.
  Blobs posted to mocha-4 are not retrievable on mocha-5.
