- Remaining items for production v3.0 release

• Previously deprecated features that have already been removed in v3 main branch
  • system channel
  • solo ordering (instead, utilize single node Raft)
  • kafka ordering (instead, utilize Raft)
  • configtxgen flag --outputAnchorPeersUpdate  flag (instead, utilize channel config updates)
  • fabric-tools image (instead, utilize client connections into Fabric networks)

• Need to finish
  • Finish SmartBFT
    • Finish tests
    • Fix frequent test failures in SmartBFT unit tests and integration test
    • Allow the peer delivery client to select between Deliverer or BFTDeliverer - PR #4856
  • Finish v1 chaincode lifecycle removal - keep external APIs but just return an error message - Tatsuya can help Artem
  • Remove ability to specify orderer endpoints in channel configuration at global level Specifying orderer endpoints ( 'Orderer.Addresses' ) at the global level in channel configuration as deprecated in v2 (instead, utilize v2 'OrdererEndpoints' in org config) - PR #4800
  • Change peer property blockGossipEnabled default to false - Block dissemination via gossip already deprecated in v2 (recommendation is to configure all peers as org leaders to receive blocks from ordering service).

• #3663 Fabric v3 epic misc items 
  • #3306 new channel config MaxWriteSize enforced with application capability V3_0, prevents large writes that potentially exceeds CouchDB max_document_size
  • #3343 ed25519 support
  • #3650 fabric-protos Go bindings based on protocol buffer APIv2 (v1 protobuf is deprecated) - potential deferral
  • #3704 older v3 ideas from Jira - e.g. Remove support for remaining Go plugins (endorsement and validation plugins) - potential deferral

  • kafka ordering (instead, utilize Raft)

  • Finish v1 chaincode lifecycle removal - keep external APIs but just return an error message - Tatsuya can help Artem

    • Legacy lifecycle has been removed from integration test and peer cli, meaning no one could use it.

    • Updated tests and removed logic that relied on legacy LCC.

    • What is still to be done?

      • Need to remove the initialization of the LSCC code as a chaincode (in progress)

      • Need to ensure peers won't crash in case we get connected to the legacy system, meaning the system is probably being upgraded. We need to ensure newly joined peers won't crash on instantiate transactions; the validation part should still be aware of these updates.

      • The last thing is mostly cosmetics to refactor the code to move or fuse legacy validation logic with new _lifecycle.

      • Ensure all documentation is updated
  • Change peer property blockGossipEnabled default to false - Block dissemination via gossip already deprecated in v2 (recommendation is to configure all peers as org leaders to receive blocks from ordering service).
