This release adds a highly requested feature: the mirror node now tracks the current account balance. Previously, the mirror node would store balance information whose source was a balance file that consensus nodes generate and upload every 15 minutes. As a result, balance information was always behind by up to 15 minutes for active accounts. We were able to figure out a way to track this information at scale with SQL in this release. The next release will actually expose this up to date account balance information on both /api/v1/accounts or /api/v1/accounts/{id}. In future releases, will look at adding live balances to /api/v1/balances when no timestamp parameter is provided and track up to date token balances.
Work continues on HIP-513 Contract Traceability, with this release adding a few important items. Consensus nodes will, when first activating the sidecar mechanism, send migration records that includes all smart contract runtime bytecode and current storage values. The mirror node now supports receiving these special migration sidecars and updating its database with the migrated data. This paves the way for the mirror node to have the necessary information to execute smart contracts without modifying state in a future release. Also in this release we now show the contract initcode that was used to unsuccessfully create a smart contract in a new failed_initcode field in the contract result REST API.
The network supply REST API saw an update to adjust the unreleased supply accounts used to calculate the unreleased supply. This change was necessary as Hedera adjusts the treasury accounts for use with staking.
