celestia-node v0.4.0

v0.4.0 | 2022-10-17

This release includes large refactorings, breaking changes and improvements related to four primary work-streams: building out the public API, hardening HeaderExchange, refactoring blocksync architecture and increasing metrics coverage.

Most notably, this release contains:

• 2 breaking changes, in addition to other improvements, to HeaderExchange as part of our work to harden and optimise it
• A large-scale refactoring to the structure of the new nodebuilder package (formerly node) as well as the way components are constructed/managed, in an effort to clarify the boundaries between components and create a cleaner foundation for building out the node's API
• Upgrade to the latest breakingcelestia-app dependency, including using instance of app instead of kvstore in our integration tests (located in nodebuilder/tests)
• Metrics coverage for das and fraud packages, in addition to increased coverage for other key celestia-node behaviours
• Consolidation of ipld and share packages into a cleaner, better defined structure, as well as general improvements to ipld to remove redundant/unnecessary behaviours
