Description

v1.1.5 is a hard fork release.

v1.1.5 brings Bruno hard fork which introduces a real-time burning mechanism into the economic model of BSC. Please refer to BEP95 for more details. The Bruno hard fork is expected to happen at block height xxx. The current block generation speed forecasts this to occur around November 30th at 08:00 AM (UTC). All clients are recommended to upgrade by November 30th.

We improved the diffsync protocol in this release and rolled it out as a stable feature. Diff sync improves the syncing speed by 60%～70% approximately according to the test. All full nodes are suggested to enable it by adding --diffsync in the starting command. Refer to BEP93 for more details.
