v0.45.0

[steven-sheehy]

The mirror node now captures the full history of changes that occur to accounts and contracts over time. Prior to this, the mirror node would only maintain the current state of a Hedera entity. With this change, all create, update and delete transaction that occur for an entity will cause a snapshot to be created to represent how it appeared at each of those points in time. This information can be used to query the API for an entity at a particular consensus timestamp in the past.

Currently, this historical lookup option is only supported on the contracts REST API. For example, you can now search for /api/v1/contracts/0.0.1000?timestamp=lte:1609480800 to see the state of the contract 0.0.1000 on January 1st, 2021. Related to contracts, we added new acceptance tests for contract related APIs. The design document was updated to detail new APIs that we are proposing to implement. Those changes are also detailed in Hedera Improvement Proposals (HIPs) for contract results and contract execution logs REST APIs. Please take a look and let us know if you have any feedback.

On the CitusDB front, we continue to make progress. All of our reference tables are now removed in favor of database or application enums. This should help improve performance and streamline the database migration. We've updated our test harness to use the latest version of CitusDB that uses PostgreSQL 14. Finally, we now create distributed tables with entity IDs used as distribution columns for partitioning and co-locate them with other tables as appropriate.

The Rosetta API also saw some improvements including the ability to create accounts online in /construction/submit. An issue with token balance reconciliation was also addressed.
