Releases: hashgraph/hedera-mirror-node
v0.7.0
0.7.0 focuses on refactoring the record file parsing to decouple the parsing from the persisting of data. This refactoring is laying the groundwork for additional performance improvements and allowing additional downstream components to register for notification of the transactions.

v0.6.0
This release was mainly focused on enhancing the stability and performance of the mirror node. We improved the transaction ingestion speed from 600 to about 4000 transactions per second. At the same time, we greatly improved the resiliency and performance of the GRPC module. We also added acceptance tests to test out HCS end to end.
Breaking Change
Please note that one potentially breaking change in this release is to reject subscriptions to topics that don't exist. This avoids the server having to poll repeatedly until it is created and taking up resources for a topic that may never exist. It is expected that clients or the SDK will poll periodically after creating a topic until that topic makes its way to the mirror node. This functionality is hidden behind a feature flag but will slowly be rolled out over the next month.
Enhancements

v0.5.3
Another bug fix release on our march to the public release of HCS. This release contains a number of stability improvements. We've also added health check and info endpoints to the GRPC and importer modules to aid in day two operations. The GRPC module also adds a new type of topic listener with the introduction of the shared poller. This is disabled by default for now, but should scale better as more users start using the service.
Enhancements
- Release v0.5.3 #517
- Add a shared poller #515
- Add /health and /info endpoints to grpc and importer #514
- Shared polling topic listener #496
- GRPC health check #476
Bug Fixes
- Improve handling of HCS missing messages #508
- Fix S3 not connecting to specific region endpoint #507
- Unable to download from new bucket temporarily #506
- Subscribe topic queries for invalid missing message sequence #505
- Fix monitor API returning invalid JSON when REST API down #503
- Monitor returns invalid response when REST API down #499
- gRPC Consensus Service Repository Query Stuck in Idle State #491

- Implemented perf module utilizing jmeter to run multi thread GRPC load test #477

v0.5.1
This release includes further bug fixes and polishing around HCS. In the near future, this release will make its way to testnet where people can try out all the new HCS functionality.
One enhancement in this release worth calling out is the change to how the mirror node verifies mainnet consensus. Previously it would wait for greater than two thirds of all signatures to be downloaded and verified using the node's public keys before storing transactions. With the change in #415, it now only needs to wait for at least one third of all signatures. Additionally, we've changed the address book to include the three additional nodes (for a total of 13) that have been participating in consensus, but whose IPs have not been made public to the world yet. Both of these changes ensure that the mirror node accurately verifies consensus.
Next release will be another bug fix release for HCS.
Enhancements
- Release v0.5.1 #494
- Final protobuf & bump to v0.5.1-rc1 #492
- Final HCS protobuf #490
- Change to at least 1/3 consensus and 13 node address book #489
- Elasticsearch Metrics #488
- HCS proto changes #482
- Update handling for CreateTopic/UpdatedTopic for HCS-0.2 #440
- Download and validate signatures for at least 1/3 of nodes rather than greater than 2/3. #415

v0.5.0
This release is the first to support the Hedera Consensus Service (HCS)! HCS provides decentralized consensus on the validity and order of messages submitted to a topic on the network and transparency into the history of these events over time. Since the Hedera mainnet does not store history, the persistence and retrieval of these messages needs to be handled by the mirror node.
As part of this effort, we've added a new component that provides a streaming GRPC API for topic message subscription. For additional information, see the design document and the protobuf definition. The Hedera Java SDK can be used to submit and subscribe to messages.
We've added a number of options to make it easier for users to run the mirror node. We've setup a demo bucket that is in use by default to allow users to get up and running with zero configuration. The real buckets are still private but we're looking at ways to open it up in the future. A community member (@carlcherry) added optional support for storing the raw transaction bytes in the database. We also added a property to filter transactions by entity or type so users running their own node can reduce their storage requirements.
Finally, there was a lot of effort in this release to restructure the code to ease future development. We
switched from a single Maven module to a multi-module project with six sub-modules. We also
reworked package names to reflect the new modules and upgraded to Spring Boot 2.2.
Expect the next release to be a maintenance release focused on stabilizing and optimizing HCS support.
