This release verifies support for PostgreSQL 17 and 18 and upgrades our managed databases from PostgreSQL 16 to PostgreSQL 18. This also required upgrading Citus from 12.1.5 to 14.0.0 and Stackgres from 1.18.3 to 1.18.6. Testing shows a significant performance gain of 10-20% from the database version bumps. Note that at this time we are not requiring a change to the minimum version of PostgreSQL that we support. We still support PostgreSQL 14 for the foreseeable future, but it is recommended that operators look to upgrade their database to 17 or 18 to stay ahead of any changes.
The /api/v1/contracts/call REST API now supports the ability for client calls to change contract state in memory and persist those changes across calls. This feature is controlled via a new property hiero.mirror.web3.evm.sharedWritableState and is disabled by default. Developers can use this feature to run a Hedera EVM locally to debug their calls. The changes are not stored in the database and will be lost upon application restart.
Breaking Changes
The REST API now returns access list as an object array instead of as a hex encoded string. While a breaking change, this field is empty in all environments since consensus nodes do not yet support them. After the consensus nodes gain Pectra support, they will add support for access lists so we took the opportunity to improve our field to be similar to the JSON-RPC specification. Below is an example of the new format:
"access_list": [
{
"address": "0xa02457e5dfd32bda5fc7e1f1b008aa5979568150",
"storage_keys": [
"0x0000000000000000000000000000000000000000000000000000000000000081",
]
}
