As the crucial underlying infrastructure of a public chain ecosystem, the mainnet’s performance determines its development. Since the mainnet launch, the IOST development team has maintained an innovative attitude and has released frequent updates and optimizations. Today, we are releasing version 3.9.2 of Olympus.
Please note that if you have not completed the Olympus v3.8.4 incompatible upgrade, you shall complete both upgrades before September 14, 2022, at 23:59 SGT, or before the block height reaches 220,000,000
Changelog:
- Upgraded Ubuntu to 20.04 and golang to 1.19;
- Upgraded the libp2p module and removed secio as mentioned in the previous upgrade notes;
- Improved statedb. To reduce disk space usage, now it does not store historical block headers;
- Added an optional field “stop” to the config file for nodes to exit after syncing blocs.
Notes:
- All nodes shall complete the upgrade before September 14, 2022, at 23:59 SGT, or before the block height reaches 220,000,000. Otherwise, the network connection may worsen until it becomes unavailable.
